4 1 Overview This document describes how to install and configure the MySQL 5.6 database in 64-bit Red Hat Enterprise Linux 6.4 before you install IMC. The installation procedures for MySQL databases of other versions might vary. For information about installing database of other versions, see their respective installation and configuration guides. Perform all operations in this document as a Linux root user, unless otherwise specified. This document uses MySQL-server el6.x86_64.rpm and MySQL-client el6.x86_64.rpm installation programs as examples. The installation procedures for the MySQL server of other versions might vary. For information about installing the MySQL server of other versions, see their respective installation and configuration guides. 4 Overview

5 2 Prerequisites Before installing the MySQL 5.6 database, install required software packages and remove the built-in MySQL database. Installing required software packages Install the following software packages in the Red Hat Enterprise Linux 6.4 environment: glibc el6.i686.rpm libaio el6.i686.rpm libgcc el6.i686.rpm libstdc el6.i686.rpm To make sure these 32-bit software packages can be successfully installed in the 64-bit Linux system, run the following commands as a root user: rpm -i --nodeps glibc el6.i686.rpm rpm -i --nodeps libaio el6.i686.rpm rpm -i --nodeps libgcc el6.i686.rpm rpm -i --nodeps libstdc el6.i686.rpm Figure 1 Installing required software packages Removing the built-in MySQL database To correctly install the MySQL 5.6 database, you must first remove the MySQL database built in the Red Hat Enterprise Linux Query the installed MySQL database and related programs. rpm qa grep mysql 2. Remove the software package. rpm e mysql-devel el6_0.1.x86_64 rpm e mysql el6_0.1.x86_64 rpm e mysql-libs el6_0.1.x86_64 Installing required software packages 5

6 3. Remove the dependent package if you receive a mysql-libs el6_0.1.x86_64 package dependency message. rpm e - nodeps mysql-libs el6_0.1.x86_64 Figure 2 Removing the built-in MySQL database Copying the installation programs to the Linux server Before installing the MySQL database, copy the installation programs to the Linux server. This document uses MySQL-server el6.x86_64.rpm and MySQL-client el6.x86_64.rpm installation programs. Figure 3 MySQL installation programs on Linux If the database and IMC are installed on the same server, install both MySQL-server el6.x86_64.rpm and MySQL-client el6.x86_64.rpm on the IMC server. If IMC is installed on a server other than the database server, install MySQL-client el6.x86_64.rpm on the IMC server and install MySQL-server el6.x86_64.rpm on the database server. You must select other server for the database location and enter the server IP address during IMC installation. 6 Prerequisites

7 3 Installation The root user in this section and the following sections refers to the MySQL database root user rather than the Linux root user, unless otherwise specified. Installing the MySQL server 1. Enter the directory where the MySQL installation programs are located and install the MySQL server. rpm -ivh MySQL-server el6.x86_64.rpm Figure 4 Installing the MySQL server 2. Start the MySQL service after the installation is complete. service mysql start 3. Verify that the MySQL service is started (3306 in the command is the default port). netstat nat grep 3306 Figure 5 Checking the MySQL service status Figure 5 shows that the MySQL service is started. Installing the MySQL client The MySQL client provides tools for MySQL management and user interaction, for example, mysqladmin and mysql. You must install the MySQL client on the IMC server to communicate with the MySQL server, local or remote. Enter the directory where the MySQL installation programs are located and install the MySQL client. rpm -ivh MySQL-client el6.x86_64.rpm Installing the MySQL server 7

8 Figure 6 Installing the MySQL client Querying the current password After the MySQL client is installed, verify whether or not it can connect to the MySQL server. The initial password of default user root can be found in the.mysql_secret file in the /root directory. Figure 7 Password storage path Query the current password in the.mysql_secret file in the /root directory. vi /root/.mysql_secret Figure 8 Opening the.mysql_secret file 8 Installation

9 Figure 9 Querying the password assigned by the MySQL server IMC with a local database The MySQL server is installed on the IMC server. After the MySQL client is installed, run the following command and enter the root user password found in the.mysql_secret file at the prompt Enter password. mysql u root p If the MySQL command line interface is displayed, then the MySQL client is installed successfully. Figure 10 Verifying the MySQL client installation IMC with a remote database The IMC server is installed with the MySQL client only. Run the following command and enter the new root user password at the prompt Enter password. mysql -h u root -p Before verifying the MySQL client installation, make sure a remote root user account has been created on the MySQL server. For information about how to create a remote root user account, see "Creating a remote root user account." Installing the MySQL client 9

10 Figure 11 Verifying the connection between the MySQL client and server In the output, is the IP address of the MySQL server and root is the remote root user account. The prompt mysql shows that the client has successfully connected to the MySQL server. Customizing MySQL file directories After the MySQL server and client are installed, the database files, configuration files, and command files are saved in different directories. Table 1 Default MySQL file directories Directory /usr/bin /usr/sbin /var/lib/mysql /usr/share/mysql /etc/init.d/ /etc Contents Client programs and scripts. MySQL service program named mysqld. Logs and database files. Configuration files, error messages, and character set files. The mysql file used to start scripts. Configuration file for MySQL startup. The file is named my.cnf, includes instances, and determines the MySQL performance. To customize the directories, modify the datadir parameter in the my.cnf file in the /etc directory. For example: datadir=/root/mysql_data For more information about changing the directories of MySQL database files, see "(Optional) Changing the log and database file directory." 10 Installation

11 4 Startup and stop Starting and stopping the MySQL service MySQL is automatically configured as the system service after the MySQL server is installed. You can start or stop the MySQL service as a common system service. Figure 12 Start and stop commands You can also use the following command to stop the MySQL service. /usr/bin/mysqladmin u root p shutdown Figure 13 Stopping the MySQL service The /usr/bin directory stores the MySQL client programs and scripts. Enter the new root user password at the prompt Enter password. Automatic startup The MySQL service automatically starts when the system boots up. Figure 14 shows how to check whether the MySQL service is on the automatic startup list. Figure 14 Checking whether the MySQL service is on the automatic startup list The output shows that the MySQL service automatically starts in Linux run levels 2 through 5. For more information about run level, see Table 2. Table 2 Run level Run level 0 1 Name Halt Single-user Mode Description Shuts Down the System. Mode for administrative tasks. Starting and stopping the MySQL service 11

12 Table 2 Run level (continued) Run level Name Multi-user Mode Multi-user Mode with Networking Not used/user-definable Start the system normally with appropriate display manager (with GUI) Reboot Description Does not configure network interfaces and does not export network services. Starts the system normally. For special purposes. Starts the system normally with display manager. Reboots the system. 12 Startup and stop

13 5 Configuring the MySQL server Setting security options 1. Run the mysql_secure_installation program. perl /usr/bin/mysql_secure_installation Figure 15 Setting the root user password 2. Enter the root user password to set security options, such as setting a root user password, removing anonymous users, and removing test database. 3. Enter n when the system asks you to change the root password. Figure 16 Choosing not to change the root user password Setting security options 13

14 4. Remove anonymous users and database test, as shown in Figure 17. If you want to use IMC with a local database, remote root user accounts must be disabled. Figure 17 Removing anonymous users, disabling remote root user accounts, and removing test database 5. When installing IMC to use a remote database, you must create a remote root user account. For information about how to create a remote root user account, see "Creating a remote root user account." 14 Configuring the MySQL server

15 6. Reload the privilege tables to make the changes effective. Figure 18 Reloading the privilege tables Changing the database password 1. Log in to the database with the password. mysql u root p 2. Enter the password at the prompt Enter password. The prompt mysql is displayed. Figure 19 Entering MySQL command line interface Changing the database password 15

16 3. Change the root user password. This example uses TLoTR123 as the new password. SET PASSWORD = PASSWORD( TLoTR123 ); Figure 20 Changing the root user password Figure 20 shows that the password has been changed successfully. Make sure the password of the root user does not include spaces, tabs (\t), or any characters in Table 3. Otherwise, the password cannot be recognized during IMC installation. For information about creating a database user account, see "Creating a local user account." Table 3 Special characters Character name Symbol Character name Symbol Back quote ` Apostrophe ' Quotation marks " Exclamation point! Left parenthesis ( Right parenthesis ) Ampersand sign & Vertical bar Back slash \ Dollar sign $ Semi-colon ; At Left angle bracket < Right angle bracket > Slash / Caret ^ Creating a database user account Creating a remote root user account MySQL server only has a local root user account by default. If you want to use IMC with a remote database, install MySQL client and configure a remote root user account on the database server. Create a remote root user account on the MySQL server. grant all privileges on *.* to root@ % identified by TLoTR123 with grant option; 16 Configuring the MySQL server

17 Figure 21 Creating a remote root user account This example uses TLoTR123 as the remote root user password. IMPORTANT: Make sure the password of the root user does not include spaces, tabs (\t), or any characters in Table 3. Otherwise, the password cannot be recognized during IMC installation. Creating a local user account Create a database user account and grant the user privileges to manage and operate the database. grant all privileges on *.* to Gandalf@ localhost identified by Sauron with grant option; Figure 22 Creating a database user account Creating a local user account 17

18 This example uses Gandalf as the user name and Sauron as the password. IMPORTANT: Make sure the password of the root user does not include spaces, tabs (\t), or any characters in Table 3. Otherwise, the password cannot be recognized during IMC installation. Creating MySQL configuration files The default configuration file /etc/my.cnf determines the performance and behavior of the MySQL server. The file is not automatically generated by the installation program, but you must copy the my-default.cnf file from the /usr/share/mysql directory to the /etc directory and rename it my.cnf. cp /usr/share/mysql/my-default.cnf /etc/my.cnf Figure 23 Copying the default configuration file Configuring parameters in the my.cnf file 1. Stop the MySQL service. 2. Open the my.cnf file. vi /etc/my.cnf Figure 24 Opening the my.cnf file 3. Press i to enter the edit mode 18 Configuring the MySQL server

19 Figure 25 Entering the edit mode 4. Add parameters under [mysqld]. Table 4 describes the parameters that can be configured in the my.cnf file. [mysqld] character-set-server = latin1 default-storage-engine = INNODB innodb_buffer_pool_size = 512M innodb_additional_mem_pool_size = 16M max_allowed_packet = 200M max_connections = 400 lower_case_table_names = 1 The latin1 is used as an example here. To prevent garbled characters appearing in imc, please choose a character set according to your operating system language. If you change the character set of MySQL after IMC has been deployed, you have to reinstall IMC. Configuring parameters in the my.cnf file 19

20 Figure 26 Adding parameters under [mysqld] Table 4 Parameters in the my.cnf file Parameters max_connections character-set-server default-storage-engine innodb_buffer_pool_size innodb_additional_mem_pool_size lower_case_table_names max_allowed_packet Description Maximum number of connections permitted by the MySQL server. You can modify this maximum number based on the number of deployed IMC components. For the maximum number allowed for each component or subcomponent, see IMC Getting Started Guide. Character sets required by the MySQL database. For example, the character sets for English, Chinese, Russian, and Japanese are latin1, gbk, cp866, and sjis, respectively. Type of the MySQL database engine: MyISAM InnoDB MEMORY MERGE Size of the InnoDB buffer pool. Size of the InnoDB additional memory pool. Indicates whether a table name is case sensitive or not. 0 Yes 1 No Size of the allowed maximum packet. 5. Search for the log-bin parameter under [mysqld] in the my.cnf file and comment out this parameter. This parameter is commented out by default. [mysqld] # log-bin 20 Configuring the MySQL server

21 Figure 27 Commenting out the log-bin parameter 6. Press Esc to return to the common mode, and enter :wq to save the my.cnf file and quit the vi editor. (Optional) Changing the log and database file directory The log and database file directory can be changed by the following steps: 1. Stop the MySQL service. service mysql stop 2. Create a path for storing logs and database files. The directory is /data/mysql_data in this example. mkdir p /data/mysql_data 3. Copy all files from the default directory to the new directory and change ownership of the files. cp R /var/lib/mysql/* /data/mysql_data/ chown R mysql:mysql /data/mysql_data 4. Add the new directory to the [mysqld] section in the my.cnf file of the MySQL database. vi /etc/my.cnf datadir=/data/mysql_data 5. Save and quit the vi editor. 6. Start the MySQL service. service mysql start (Optional) Changing the log and database file directory 21

22 6 Uninstallation IMC with a local database 1. Stop the MySQL service. service mysql stop 2. Uninstall the MySQL database. rpm e MySQL-client el6.x86_64 rpm e MySQL-server el6.x86_64 The following command can be used to query the component name. rpm -qa grep MySQL Figure 28 Uninstalling the MySQL database 3. Manually remove database files in the default /var/lib/mysql directory after uninstallation. rm -rf /var/lib/mysql After the directory is removed, the MySQL database is removed successfully. IMC with a remote database Uninstall the MySQL database. rpm -qa grep MySQL rpm e MySQL-client el6.x86_64 Figure 29 Searching for the MySQL component 22 Uninstallation

23 7 FAQ Why do garbled characters appear in the database table? Configure the correct character set when you install the MySQL server and client. Otherwise, garbled characters can appear in the database table. For more information, see Table 4. How do I update the database password for the IMC server? The user names and passwords used by IMC components are stored in ciphertext in the /common/conf/server-addr.xml file in the IMC installation directory. You can use the./pwdmgr command to obtain passwords in plain text or save the new passwords in ciphertext to the file You can use the database management tool to change the database password of an IMC component. After the change, you must use the./pwdmgr command to update the corresponding password in the server-addr.xml file to make sure IMC can communicate with the database. If IMC is deployed in distributed mode, you must update the database password on every IMC server. [root@daemon8829 ~]# cd /opt/imc/deploy/ [root@daemon8829 deploy]#./pwdmgr.sh modify config_db imc_config dbpasswd Change password successfully The dbpasswd string indicates the new database password of the imc_config user. The config_db string indicates the database name. The string indicates the database IP address. To obtain the IP address and name of a MySQL database, view information about the corresponding user in the $IMCROOT/common/conf/server-addr.xml file. 23
