10.6.12.119 （安装zk,codis-server-master，codis-dashboard,codis-proxy,codis-fe）
10.6.12.120 （安装zk,codis-server-master,codis-proxy）
10.6.12.121 （安装zk,codis-server-master,codis-proxy）

关闭防火墙
systemctl stop firewalld
安装jdk
步骤省略
下载一个zookeeper的安装包
mv zookeeper-3.4.14.tar.gz /usr/local
cd /usr/local
tar zxvf zookeeper-3.4.14.tar.gz
cd zookeeper-3.4.14
mkdir data
mkdir logs
cd conf
touch zoo.cfg
vim zoo.cfg

cd /usr/local/zookeeper-3.4.14
新建data/myid
#10.6.12.119
echo '1' > data/myid
#10.6.12.120
echo '2' > data/myid
#10.6.12.121
echo '3' > data/myid
#10.6.12.122
echo '4' > data/myid
依次启动
cd bin
./zkServer.sh start
全部启动之后
/usr/local/zookeeper-3.4.14/bin/zkServer.sh status
查看选出的leader 121
安装go
go安装目录/usr/local/go：
tar -zxf go1.9.1.linux-amd64.tar.gz -C /usr/local/
在/etc/profile文件末尾加配置
echo '
export GOPATH=/usr/local/codis
export GOROOT=/usr/local/go
export PATH=$PATH:/usr/local/go/bin
' >> /etc/profile
#使/etc/profile马上生效----------------------------------------------------------------------
source /etc/profile
重新加载/etc/profile
source /etc/profile
检测是否安装成功
go version
安装codis3.2
1、安装依赖
yum install autoconf automake libtool -y
yum install -y gcc glibc gcc-c++ make git
2、设置编译环境
下载并编译codis（codis-config、codis-proxy、codis-serve）
codis编译目录必须为$GOPATH/src/github.com/CodisLabs，否则编译时报找不到目录，
将codis-release3.2.zip解压到此目录后改名为codis：
unzip codis-release3.2.zip
mkdir -p $GOPATH/src/github.com/CodisLabs
mv codis-release3.2 $GOPATH/src/github.com/CodisLabs/codis
3、编译Codis源码
cd $GOPATH/src/github.com/CodisLabs/codis
make
#复制文件，更改codis目录，方便管理
mkdir -p /usr/local/codis/{bin,logs,data}/
cp -rf $GOPATH/src/github.com/CodisLabs/codis/bin/* /usr/local/codis/bin
cp -rf $GOPATH/src/github.com/CodisLabs/codis/config /usr/local/codis/
安装dashboard
修改/usr/local/codis/config/dashboard.toml

/usr/local/codis/codis-admin --remove-lock --product=codis-demo --zookeeper=10.6.12.119:2181
安装proxy

cd /usr/local/codis/logs/
nohup /usr/local/codis/bin/codis-proxy --ncpu=4 --config=/usr/local/codis/config/proxy.toml --log=/usr/local/codis/logs/proxy.log --log-level=WARN &
接着启动120和121的proxy
Codis-admin
关联proxy到dashboard
#主机10.6.12.119上执行
/usr/local/codis/bin/codis-admin --dashboard=10.6.12.119:18080 --create-proxy --addr=10.6.12.119:11080
加入之后 会从proxy waiting online ...变成proxy is working ...
同理在119上加入其余proxy
/usr/local/codis/bin/codis-admin --dashboard=10.6.12.119:18080 --create-proxy -x 10.6.12.120:11080 (用上面的命令也可以)
/usr/local/codis/bin/codis-admin --dashboard=10.6.12.119:18080 --create-proxy --addr=10.6.12.121:11080
如果出现报错 [Remote Error] topom is not online
/usr/local/codis/bin/codis-admin --remove-lock --product=codis-proxy --zookeeper=172.16.129.86:2181 即可
Codis-Server
即创建redis实例,每台主机都创建2个redis实例
mkdir -p /usr/local/codis/redis/6379
mkdir -p /usr/local/codis/redis/6380
cp $GOPATH/src/github.com/CodisLabs/codis/config/redis.conf /usr/local/codis/redis/6379
cp $GOPATH/src/github.com/CodisLabs/codis/config/redis.conf /usr/local/codis/redis/6380
修改/usr/local/codis/redis/6379/redis.conf配置文件

启动codis-server
后面需要使用 Codis-fe或者Codis-admin 添加到集群
nohup /usr/local/codis/bin/codis-server /usr/local/codis/redis/6379/redis.conf &
nohup /usr/local/codis/bin/codis-server /usr/local/codis/redis/6380/redis.conf &
/usr/local/codis/bin/codis-fe --ncpu=4 --log=/usr/local/codis/logs/fe.log --log-level=WARN --zookeeper=10.6.12.119:2181 --listen=0.0.0.0:8888 &
在fe界面查看、添加proxy代理服务。
proxy启动默认会自动注册到dashboard中，也可以在fe中手动添加,
“Proxy Admin Address”选项中分别填写如下内容，然后点击“New Proxy”按钮添加
10.6.12.119:11080
10.6.12.120:11080
10.6.12.120:11080
备注：主机的codis-proxy服务需要启动，11080端口是互通的，才能添加成功，结果如下：
部署codis-server加入集群
添加group
Group栏为空，因为我们启动的codis-server并未加入到集群，启动所有主机codis-server服务，
“NEW GROUP”选项分别输入输入1，2，3，点击NEW GROUP添加3个Group。
添加实例（按照部署规划，添加redis服务）
“Data Center” 选项填 空
“Codis Server Address” 选项填10.6.12.119:6379
“Group”选项填1
“Data Center” 选项填 空
“Codis Server Address” 选项填10.6.12.119:6380
“Group”选项填1
出现下面错误 请确认密码是否正确
slots分组和codis集群测试
