codis集群搭建
一、搭建过程
官方文档：https://github.com/CodisLabs/codis/blob/release3.2/doc/tutorial_zh.md
（一）、软件及配置位置
1、上传bin.tar至/opt/app/codis下（tar -xvf bin.tar），将配置放在/opt/app/codis/ripsg/config下
（二）、启动过程
注：启动dashboard、proxy、fe（先获取codis.json）、server、sentinel
1、启动dashboard
cd /opt/app/codis
nohup ./bin/codis-dashboard --ncpu=4 --config=ripsg/config/dashboard_18080.toml --log=dashboard.log --log-level=WARN &
2、启动proxy
cd /opt/app/codis
nohup ./bin/codis-proxy --ncpu=4 --config=ripsg/config/proxy_11080.toml --log=proxy.log --log-level=WARN &
3、启动fe
a、用admin命令获取codis.json
cd /opt/app/codis/bin
./codis-admin --dashboard-list --zookeeper=10.221.7.54:2181 | tee codis.json
b、启动fe
cd /opt/app/codis/bin
nohup ./codis-fe --ncpu=4 --log=fe.log --log-level=WARN --dashboard-list=codis.json --listen=10.221.7.57:9090 &
c、登录fe
http://p:9090
4、启动redis-server
cd /opt/app/codis
./bin/codis-server ripsg/config/group_1/redis_6480.conf
5、启动redis-sentinel
cd /opt/app/codis
./bin/codis-server ripsg/config/sentinel_26480.conf --sentinel &
（三）、在dashboard上配置
1、添加proxy
2、添加group
3、分配slots
4、添加sentinel
二、常用指令
1、master客户端登录：./redis-cli -p 6480 -h ip -a '[email protected]'
2、proxy客户端登录：./redis-cli -p 19000 -h ip -a '[email protected]'
3、codis版本信息：./codis-server --version
三、配置说明
注：redis_6480.conf、sentinel_26480.conf无个性ip；proxy_11080.toml、dashboard_18080.toml有个性ip
