codis安装入门

前期准备：

3台云服务器（服务器ip和域名配置详情可见最下方的host配置)

172.16.0.6 instance-oi4hyxs3  （2C4G）（安装zk,codis-server-master，codis-dashboard,codis-proxy,codis-fe）
172.16.0.4 instance-drr9py6i   （1C2G）（安装zk,codis-server-master,codis-proxy）
172.16.0.5 instance-lbmhmbfu （1C1G）（安装zk,codis-server-slave作为2C4G的从库）

1.安装go环境和zk环境

2.yum install -y gcc git autoconf

3.下载编译codis

mkdir -p $GOPATH/src/github.com/CodisLabs
cd $_ && git clone https://github.com/CodisLabs/codis.git -b release3.2
cd $GOPATH/src/github.com/CodisLabs/codis
make

4.安装codis-server(redis-server)

./codis-server /usr/local/gopath/src/github.com/CodisLabs/codis/config/redis.conf

5.安装codis-dash

启动nohup ./codis-dashboard --config=/usr/local/gopath/src/github.com/CodisLabs/codis/config/dashboard.toml --ncpu=1 --log=/home/local/codis/codis-dashboard/log/dashboard.log --log-level=INFO > dash.txt &停止
./codis-admin --dashboard=localhost:18080   --shutdown当dash异常退出时，重启启动会报错，需要删除zk上的注册信息
./codis-admin --remove-lock --product=codis-vk --zookeeper=zk1.idc.baiduyun.com:2181,zk2.idc.baiduyun.com:2181,zk3.idc.baiduyun.com:2181

6.安装codis-proxy

启动
nohup ./codis-proxy --ncpu=1  --config=/usr/local/gopath/src/github.com/CodisLabs/codis/config/proxy.toml --log=/home/local/codis/codis-proxy/log/proxy.log --log-level=INFO > proxy.txt &停止
./codis-admin --proxy=127.0.0.1:11080 --shutdown

7.安装codis-fe

生成fe的配置文件
./codis-admin --dashboard-list --zookeeper=zk1.idc.baiduyun.com:2181,zk2.idc.baiduyun.com:2181,zk3.idc.baiduyun.com:2181 | tee codis.json启动
nohup ./codis-fe --log=/home/local/codis/codis-fe/log/fe.log --log-level=INFO --dashboard-list=/usr/local/gopath/src/github.com/CodisLabs/codis/config/codis.json --listen=0.0.0.0:18090 --ncpu=1 > fe.txt &

8.访问fe界面初始化集群

8.1 访问fe界面：
http://localhost:18090
8.2 添加codis-proxy代理到codis-dash中

8.3添加codis-server到group中

8.4 分配salt(0~1023)到每个组

8.5 分配需要一段时间，分配完成后，图中会显示每个组所占salt范围
