2.启动codis-proxy
nohup /app/codis/bin/codis-proxy --ncpu=4--config=/app/codis/bin/proxy.toml --log=proxy.log --log-level=WARN &
四、部署codis-dashboard
1.生成codis-proxy配置文件
/app/codis/bin/codis-dashboard--default-config |tee dashboard.toml >>dashboard.toml
修改codis-proxy配置
vidashboard.toml
##################################################
# #
# Codis-Dashboard #

coordinator_name外部存储类型，接受 zookeeper/etcd
coordinator_addr外部存储地址
product_name集群名称，满足正则 \w[\w\.\-]*
product_auth集群密码，默认为空
admin_addrRESTful API 端口
启动codis-dashboard
nohup/app/codis/bin/codis-dashboard --ncpu=4 --config=/app/codis/bin/dashboard.toml --log=dashboard.log --log-level=WARN &
五、部署codis-fe
5.1生成codis-fe配置文件
/app/codis/bin/codis-admin --dashboard-list --zookeeper=172.16.40.131:2182 |tee ./codis.json>>codis.json
[root@codis-02bin]# cat codis.json
[
{
"name":"codis-demo",
"dashboard":"172.16.40.131:18080"
}
]
启动codis-fe服务
nohup/app/codis/bin/codis-fe --ncpu=4 --log=fe.log --log-level=WARN --dashboard-list=/app/codis/bin/codis.json --listen=0.0.0.0:18090 &
查看相关服务端口
[root@codis-02bin]# ss -tunlp | grep codis
tcp LISTEN 0 128 *:19000 *:* users:(("codis-proxy",10106,7))
tcp LISTEN 0 128 *:7001 *:* users:(("codis-server",10063,4))

tcp LISTEN 0 128 :::18090 :::* users:(("codis-fe",10221,5))
六、redis sentinel部署
创建redis-sentinel目录
mkdir -pv /app/codis/sentinel/{27001,27002}
配置sentinel文件
vi /app/codis/sentinel/27001/sentinel-27001.conf
bind 0.0.0.0
protected-mode no
port 27001
dir /app/codis/sentinel/27001/
vi /app/codis/sentinel/27002/sentinel-27002.conf
bind 0.0.0.0
protected-mode no
port 27002
dir /app/codis/sentinel/27002/
启动sentinel服务
cp/app/gopkg/src/github.com/CodisLabs/codis/extern/redis-3.2.8/src/redis-sentinel/app/codis/bin/
/app/codis/bin/redis-sentinel /app/codis/sentinel/27001/sentinel-27001.conf &
/app/codis/bin/redis-sentinel /app/codis/sentinel/27002/sentinel-27002.conf &
七、使用codis-fe管理codis集群环境
1.codis-fe管理界面
http://172.16.40.131:18090
添加codis-proxy：
采用命令增加
[root@codis-02 bin]# ./codis-admin --dashboard=127.0.0.1:18080 --create-proxy -x 127.0.0.1:11080
也可以采用界面增加
添加codis-server
先NEW GROUP
增加一主两从
增加两组
以上也可以用命令增加
添加redis-sentinel
命令增加
[root@codis-02bin]# ./codis-admin --dashboard=172.16.40.131:18080 --sentinel-add --addr=172.16.40.131:27002
分配 slot
slot：数据槽，在 codis-server 间数据分片的单元；建议将数据槽均分于多个 group；
在 codis-fe 管理界面添加 redis-sentinel，并同步，同步后 redis-sentinel 配置文件会更新
root@codis-02bin]# cat /app/codis/sentinel/27001/sentinel-27001.conf
bind 0.0.0.0
protected-mode no
port 27001
dir "/app/codis/sentinel/27001"
