Adding the mster host to resource pool Complete this procedure to dd the Control Center mster host to the defult resource pool or to new resource pool nmed mster. 1 Gin ccess to the Control Center host, through the console interfce of your hypervisor, or through remote shell utility such s PuTTY. 2 Strt commnd-line session s root s follows: In the Applince Administrtion menu, select Root Shell. Select Run, nd then press Enter. The menu is replced y commnd prompt similr to the following exmple: [root@hostnme ~]# 3 Optionl: Crete new resource pool, if necessry. For single-host deployments, skip this step. For multi-host deployments, perform the following susteps. Crete new pool nmed mster. serviced pool dd mster Assign dministrtive nd distriuted file system (DFS) permissions to the new resource pool. serviced pool set-permission --dmin --dfs mster 4 Add the mster host to resource pool. For single-host deployments, dd the mster host to the defult resource pool. Replce Hostnme-Or-IP with the hostnme or IP ddress of the Control Center mster host: serviced host dd Hostnme-Or-IP:4979 defult If you enter hostnme, ll hosts in your Control Center cluster must e le to resolve the nme, either through n entry in /etc/hosts, or through nmeserver on your network. For multi-host deployments, dd the mster host to the mster resource pool nd register its uthentiction token. Replce Hostnme-Or-IP with the hostnme or IP ddress of the Control Center mster host: serviced host dd --register Hostnme-Or-IP:4979 mster If you enter hostnme, ll hosts in your Control Center cluster must e le to resolve the nme, either through n entry in /etc/hosts, or through nmeserver on your network. 5 To exit the commnd-line session, t the commnd prompt, enter exit. Deploying Cisco UCS Performnce Mnger You cn use the rowser interfce or the commnd-line interfce to deploy Cisco UCS Performnce Mnger. Choose one of the procedures in this section. 14

15 Instlling Control Center mster host Using the CLI to deploy This procedure dds the Cisco UCS Performnce Mnger ppliction to the list of pplictions tht Control Center mnges. 1 Gin ccess to the Control Center host, through the console interfce of your hypervisor, or through remote shell utility such s PuTTY. 2 Strt commnd-line session s root s follows: In the Applince Administrtion menu, select Root Shell.

27 Configuring multi-host Control Center cluster Configuring multi-host Control Center 3 cluster This chpter descries how to configure multi-host Control Center cluster. A multi-host Cisco UCS Performnce Mnger deployment includes one Control Center mster host nd three Control Center delegte hosts. If you re creting Cisco UCS Performnce Mnger deployment on vsphere system, skip hed to Adding hosts to the defult resource pool on pge 31. Otherwise, complete ll of the procedures in this chpter. Enling NTP on Microsoft Hyper-V guests Note The procedures in this section re required only for multi-host deployments running s Microsoft Hyper-V guests. VMwre vsphere guests use n hourly cron jo to synchronize their system clocks with the host. Like most distriuted pplictions, Control Center requires common time source. The procedures in this section enle NTP to synchronize the system clocks of ll hosts in your Control Center cluster. Configure NTP to rely on time source s follows, depending on internet ccess of the hosts in your Control Center cluster: If ll hosts cn ccess the internet, configure NTP to rely on pulic time servers. If no host cn ccess the internet, configure NTP to rely on privte mster server. Configuring NTP for pulic time servers (Hyper-V only) This procedure uses the defult configurtion of NTP to synchronize system clocks with pulic time servers. If ll hosts in the Control Center cluster cn ccess the internet, repet this procedure on ech host in the cluster, strting with the Control Center mster host. 1 Gin ccess to the Control Center host, through the console interfce of your hypervisor, or through remote shell utility such s PuTTY. 2 Strt commnd-line session s root s follows: In the Applince Administrtion menu, select Root Shell. Select Run, nd then press Enter. The menu is replced y commnd prompt similr to the following exmple: [root@hostnme ~]# 27

32 Cisco UCS Performnce Mnger Instlltion Guide Configuring ZooKeeper ensemle 4 This chpter descries how to crete ZooKeeper ensemle (cluster) for multi-host Control Center deployment tht includes minimum of three hosts. If your deployment includes just one host or two hosts, skip this chpter. ZooKeeper nd Control Center Control Center relies on Apche ZooKeeper to distriute nd mnge ppliction services. ZooKeeper mintins the definitions of ech service nd the list of services ssigned to ech host. The scheduler, which runs on the mster host, determines ssignments nd sends them to the ZooKeeper node tht is serving s the ensemle leder. The leder replictes the ssignments to the other ensemle nodes, so tht the other nodes cn ssume the role of leder if the leder node fils. All of the hosts in Control Center cluster retrieve ssignments nd service definitions from the ZooKeeper ensemle leder nd then strt services in Docker continers s required. So, the Control Center configurtion files of ll Control Center cluster hosts must include definition for the SERVICED_ZK vrile, which specifies the ZooKeeper endpoints of the ensemle nodes. Additionl vriles re required on ensemle nodes. A ZooKeeper ensemle requires minimum of three nodes, which is sufficient for most environments. An odd numer of nodes is recommended nd n even numer of nodes is strongly discourged. A five-node ensemle improves filover protection during mintennce windows ut lrger ensemles yield no enefits. The Control Center mster host is lwys n ensemle node. All ensemle nodes should e on the sme sunet. Understnding the configurtion process The procedures in this chpter instruct you to crete temporry vriles tht re used s uilding locks, to construct Control Center configurtion vriles ccurtely. You ppend the Control Center vriles to /etc/ defult/serviced, nd then edit the file to move the vriles to more pproprite loctions. The most importnt temporry vriles specify the IP ddress or hostnme of ech host in the ZooKeeper ensemle. The following tle identifies these importnt vriles, the nmes nd vlues of which must e identicl on every Control Center cluster host. Vrile nme Plceholder vlue Actul vlue node1 Mster The IP ddress or hostnme of the mster host. node2 Delegte-A The IP ddress or hostnme of delegte host A. 32
