修改内核参数

配置互信
1 2 | ./sshUserSetup.sh -user gbase -hosts "gbase8c gbase8c" -advanced exverify –confirm chmod 600 /home/gbase/.ssh/config |
解压安装包
解压安装包 GBase8cV5_S3.0.0B76_centos7.8_x86_64.tar.gz：
1 2 3 4 5 6 | su - gbase mkdir -p /home/gbase/gbase_package cp /soft/GBase8cV5_S3.0.0B76_centos7.8_x86_64.tar.gz /home/gbase/gbase_package cd /home/gbase/gbase_package tar -zxvf GBase8cV5_S3.0.0B76_centos7.8_x86_64.tar.gz tar zxf GBase8cV5_S3.0.0B76_CentOS_x86_64_om.tar.gz |
开始安装
配置gbase8c.yml文件
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 | cat > /home/gbase/gbase_package/gbase.yml <<"EOF" gha_server: - gha_server1: host: 127.0.0.1 port: 20001 dcs: - host: 127.0.0.1 port: 2379 gtm: - gtm1: host: 127.0.0.1 agent_host: 127.0.0.1 role: primary port: 6666 agent_port: 8001 work_dir: /home/gbase/data/gtm/gtm1 coordinator: - cn1: host: 127.0.0.1 agent_host: 127.0.0.1 role: primary port: 5432 agent_port: 8003 work_dir: /home/gbase/data/coord/cn1 datanode: - dn1: - dn1_1: host: 127.0.0.1 agent_host: 127.0.0.1 role: primary port: 15432 agent_port: 8005 work_dir: /home/gbase/data/dn1/dn1_1 - dn2: - dn2_1: host: 127.0.0.1 agent_host: 127.0.0.1 role: primary port: 20010 agent_port: 8007 work_dir: /home/gbase/data/dn2/dn2_1 env: # cluster_type allowed values: multiple-nodes, single-inst, default is multiple-nodes cluster_type: multiple-nodes pkg_path: /home/gbase/gbase_package # 安装包所在路径 prefix: /home/gbase/gbase_db # 运行目录 version: V5_S3.0.0B76 # 与安装包版本一致 GBase8cV5_S3.0.0B76 user: gbase port: 22 # constant: # virtual_ip: 172.72.3.36/24 EOF |
执行安装脚本
1 2 3 | su - gbase cd /home/gbase/gbase_package/script ./gha_ctl install -c gbase -p /home/gbase/gbase_package -f |
注释：
-c 参数：数据库名称，默认 gbase
-p 参数：配置文件路径，默认 /home/gbase-f参数：若集群已存在，可以强制安装
安装日志位置
1 2 3 | tailf /tmp/gha_ctl/gha_ctl.log cd /home/gbase/gbase_db/log/om/ |
执行时间约 5 分钟，安装结束后，脚本会提示：
1 2 3 4 | { "ret":0, "msg":"Success" } |
集群安装成功！
状态检查
执行
1 2 | /home/gbase/gbase_package/script/gha_ctl monitor -l http://127.0.0.1:2379 /home/gbase/gbase_package/script/gha_ctl monitor -l http://127.0.0.1:2379 -H |
结果如下，说明集群安装正常，数据服务启动中
