6 1. Image environment 1.1. Image version Operating system: Centos bit Software details of image: Nginx PHP MySQL Joomla! Image installation root/joomla.tar.gz is the script we used to install the image. you can use it for the image environment installation in Centos 7.2 by yourself, the manually installed environment is the same as the initialized image environment. Note that if you use this script to install the image environment, you need to run chmod 777 -R /root/joomla to grant 777 installation privileges. /root/joomla is the main directory for installing the environment, in which the image environment is compiled and installed

7 2. Password for mysql and ftp 2.1. Password file /alidata/account.log 2.2. View Password Logon your server, in any directory, you can execute the following command to view the password: cat /alidata/account.log 2.3. Change ftp password Logon mongodb server with root accoutn, then execute below commands: passwd www Then enter new password for ftp Change mysql password mysqladmin -uroot p Old password password new password Note: There is no space between -p and old password, and there is a space between password and new password

8 3. Software directory and configuration list software main directory: /alidata web root directory: /alidata/www Ftp home directory: /alidata/www Nginx directory: /alidata/server/nginx Nginx configuration file home directory: / alidata / server / nginx / conf Php home directory: / alidata / server / php Php configuration file: / alidata / server / php / etc Mysql directory: /alidata/server/mysql Mysql configuration file: /etc/my.cnf Joomla Chinese support package: / alidata / res Log directory: /alidata/log/nginx /alidata/log/php /alidata/log/mysql Init directory: /alidata/init When a user creates a system with this image, the ftp and mysql passwords (random passwords) will be initialized with this script when and only if the user starts the system for the first time

9 4. Software operation command summary systemctl start stop restart mysqld.service systemctl start stop restart vsftpd.service systemctl start stop restart nginx.service 5. Uninstallation Execute below commands for uninstallation: cd /root/joomla./uninstall.sh Note: 1: This operation will clean up /alidata directory. Before uninstallation, please back up the necessary data. 2: If / root / joomla directory is mistakenly deleted, you can extract /root/mariadb.zip to get this directory again. you can refer to the following commands: cd tar zvf joomla.tar.gz chmod 777 -R joomla cd joomla./uninstall.sh

10 6. Appendix Tutorial 1: configure remote connection For security reason, joomla default setting only allows local access. there is a script called joomla_opennet.sh under /root/joomla directory, executing it will enable joomla remote access. Tutorial 2: configure joomla At the first time you login server system that is installed by the image, run /root/joomla/joomla_opennet.sh, then type in browser, click Enter, you will see the initialized page of joomla. 1) Select language, fill out the other configurations, then click "Next"

11 2) select the mysql database, enter the account and the password, click "Next". 3) Double check the configurations, then click "install"

12 4) After the installation done, go to /alidata/www/default directory, type below commands to delete the installation directory

13 cd /alidata/www/default rm -rf installation/ now,the installation is completely finished. Visit the front-end site: http: // ip Visit the background management interface: http: //ip/administrator. Tutorial 3: Migrate the site to the data disk The site data of the image is stored in system disk. Considering that the system disk space may not be sufficient, if the amount of application data is too large, you may need to move it to the data disk. The specific steps are as follows: 1) Firstly, partition and format the data disk. If you have already formatted the

14 data disk, ignore this step. 2)Take Appendix tutorial 1: deploy joomla as an example, execute the following commands to migrate joomla to the data disk: /etc/init.d/nginx stop rm -rf installation/ /etc/init.d/php-fpm stop cd / #stop the nginx service first # stop php service # switch to the root directory mount /dev/xvdb1 /mnt/ # Mount the first data disk under the mnt directory. The mount point depends on your needs, here we just use mnt directory as an example. Mounting /dev/xvdb1 /alidata/www directly to the /alidata/ www directory seems more convenient. mkdir -p /mnt/www /mnt/log cp -a /alidata/www/default /mnt/www # migrate data to the data disk 3)vim / alidata/server/nginx/conf.d/vhost/default.conf Change "/root/alidata/www/default;" "Access_log / alidata/log/nginx/access/default.log;" to "/mnt/www/default;"

15 "access_log /mnt/log/default.log;" 4) start php nginx, then the migration done. /etc/init.d/php-fpm start /etc/init.d/nginx start Tutorial 4: Migrate mysql to the data disk The installation directory and data directory of image are both installed in system disk. Considering that the system disk space may not be sufficient, if the amount of mysql data is too large, you may need to move mysql to the data disk, which usually means migrating the data directory of mysql to the data disk. The specific steps are as follows: 1) First, format the data disk and mount it under /mnt directory (the mount point depends on your requirement, here we just take /mnt as an example) mkdir -p /mnt/data 2) Use mysqldump command to export all data of your project. mysqldump -p --all-databases > all.sql 3) Stop mysql /etc/init.d/mysqld stop 4) edit /etc/init.d/mysqld file

16 Change datadir=/alidata/server/mysql/data To datadir=/mnt/data 5) Then initialize the database environment with below command: /alidata/server/mysql/scripts/mysql_install_db --basedir=/alidata/server/mysql --datadir=/mnt/data --user=mysql Note: here the datadir is the new directory you will migrate mysql to 6) Start mysql, then restore the data to the new data disk /etc/init.d/mysqld start mysql < all.sql /etc/init.d/mysqld restart Tutorial 5: configure mysql remote connection A lot of users feedback, after generating system with the image, the cloud host itself can connect mysql, but the remote connections from other machine fail. It is because the default installation of mysql, for security reasons, can only be connected locally. If you want remote access, you need to set the mysql permission table. The specific steps are as follows:

17 1) Connect mysql on your cloud host. 2) Execute twi command: use mysql #open the mysql database 3) Setting the host to % means any ip can connect mysql. Of course, you can also specify the host as a fixed ip: update user set host='%' where user='root' and host='localhost'; flush privileges; #Refresh the permissions table to make the configuration take effect Then we can connect mysql remotely with root user Note: You can also add a user named yuancheng with the password , the authority is % (that means it can be connected by any ip): Grant all on *. * To '%' identified by '123456'; Flush privileges; 4) If you want to turn off remote connections, restore mysql to the default settings (only local connection permitted), you can do the followings: use mysql #open the mysql database update user set host='localhost' where user='root'; #Setting host to the localhost means you can only connect mysql locally

18 flush privileges; #Refresh the permission table to make the configurations take effect
