基於CentOS系統安裝OceanBase資料庫
一、OceanBase介紹
二、OceanBase安裝操作
[root@oceanbase ~]# cat /etc/redhat-release CentOS Linux release 7.9.2009 (Core)
1、透過 YUM 軟體源下載並安裝 OBD
# yum install -y yum-utils # yum-config-manager --add-repo # yum install -y ob-deploy
[root@obd ~]# yum install -y yum-utils Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Package yum-utils-1.1.31-54.el7_8.noarch already installed and latest version Nothing to do [root@obd ~]# yum-config-manager --add-repo Loaded plugins: fastestmirror adding repo from: grabbing file to /etc/yum.repos.d/OceanBase.repo repo saved to /etc/yum.repos.d/OceanBase.repo [root@obd ~]# yum install -y ob-deploy Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Package ob-deploy-1.2.1-9.el7.x86_64 already installed and latest version Nothing to do [root@obd ~]#
離線安裝 OBD 1. 下載 OBD 離線 RPM 安裝包。 2. 執行以下命令安裝 OBD。 # yum install -y ob-deploy-1.0.0-1.el7.x86_64.rpm # source /etc/profile.d/obd.sh
2、下載 OceanBase 資料庫配置檔案模板
oceanbase-ce: servers: # Please don't use hostname, only IP can be supported - 127.0.0.1 global: # The working directory for OceanBase Database. OceanBase Database is started under this directory. This is a required field. home_path: /xyb/observer # The directory for data storage. The default value is $home_path/store. # data_dir: /data # The directory for clog, ilog, and slog. The default value is the same as the data_dir value. # redo_dir: /redo # Please set devname as the network adaptor's name whose ip is in the setting of severs. # if set severs as "127.0.0.1", please set devname as "lo" # if current ip is 192.168.1.10, and the ip's network adaptor's name is "eth0", please use "eth0" devname: lo mysql_port: 2881 # External port for OceanBase Database. The default value is 2881. DO NOT change this value after the cluster is started. rpc_port: 2882 # Internal port for OceanBase Database. The default value is 2882. DO NOT change this value after the cluster is started. zone: zone1 cluster_id: 1 # please set memory limit to a suitable value which is matching resource. memory_limit: 8G # The maximum running memory for an observer system_memory: 4G # The reserved system memory. system_memory is reserved for general tenants.

This value takes effect only when datafile_size is 0. The default value is 90. syslog_level: INFO # System log level. The default value is INFO. enable_syslog_wf: false # Print system logs whose levels are higher than WARNING to a separate log file. The default value is true. enable_syslog_recycle: true # Enable auto system log recycling or not. The default value is false. max_syslog_file_count: 4 # The maximum number of reserved log files before enabling auto recycling. The default value is 0. # root_password: # root user password, can be empty
3、部署 OceanBase 資料庫
