二、部署zookeeper集群

1.安装相关依赖包

yum install -y gcc makegcc-c++ automake lrzsz openssl-devel zlib-* bzip2-* readline* git nmap unzipwget lsof xz net-tools mercurial

2.安装java

tar zxvfjdk-8u111-linux-x64.gz -C /usr/local/

cd /usr/local/

ln -sv jdk1.8.0_111  java

修改环境变量

vi /etc/profile

JAVA_HOME=/usr/local/java

PATH=$JAVA_HOME/bin:$PATH

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export JAVA_HOME

export PATH

export CLASSPATH

让环境变量生效

source /etc/profile

查看JAVA版本

java -version

java version "1.8.0_111"

Java(TM) SE Runtime Environment (build1.8.0_111-b14)

Java HotSpot(TM) 64-Bit Server VM (build25.111-b14, mixed mode)

3.安装zookeeper

cd /app

mkdir -pv ./{zk1,zk2,zk3}/{data,log}

tar zxvf zookeeper-3.4.6.tar.gz -C /app/zk1/

tar zxvf zookeeper-3.4.6.tar.gz -C /app/zk2/

tar zxvf zookeeper-3.4.6.tar.gz -C /app/zk3/

ln -sv /app/zk1/zookeeper-3.4.6 /app/zk1/zookeeper

ln -sv /app/zk2/zookeeper-3.4.6 /app/zk2/zookeeper

ln -sv /app/zk3/zookeeper-3.4.6 /app/zk3/zookeeper

cp /app/zk1/zookeeper/conf/zoo_sample.cfg/app/zk1/zookeeper/conf/zoo.cfg

修改zoo.cfg配置文件

vi /app/zk1/zookeeper/conf/zoo.cfg

# The number of milliseconds of each tick

tickTime=2000

# The number of ticks that the initial

# synchronization phase can take

initLimit=10

# The number of ticks that can pass between

# sending a request and getting anacknowledgement

syncLimit=5

# the directory where the snapshot isstored.

# do not use /tmp for storage, /tmp here isjust

# example sakes.

dataDir=/app/zk1/data

# the port at which the clients willconnect

clientPort=2181

# the maximum number of client connections.

# increase this if you need to handle moreclients

#maxClientCnxns=60

#

# Be sure to read the maintenance sectionof the

# administrator guide before turning onautopurge.

#

#http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

#

# The number of snapshots to retain indataDir

# Purge task interval in hours

# Set to "0" to disable autopurge feature

#autopurge.purgeInterval=1

server.1=172.16.40.131:2881:3888

server.2=172.16.40.131:2882:3888

server.3=172.16.40.131:2883:3888

生成myid

echo "1">/app/zk1/data/myid

配置zk2、zk3:

cp /app/zk1/zookeeper/conf/zoo.cfg /app/zk2/zookeeper/conf/

cp /app/zk1/zookeeper/conf/zoo.cfg /app/zk3/zookeeper/conf/

sed -i 's/zk1/zk2/g' /app/zk2/zookeeper/conf/zoo.cfg

sed -i 's/zk1/zk3/g' /app/zk3/zookeeper/conf/zoo.cfg

sed -i 's/2181/2182/g' /app/zk2/zookeeper/conf/zoo.cfg

sed -i 's/2181/2183/g' /app/zk3/zookeeper/conf/zoo.cfg

echo "2">/app/zk2/data/myid

echo "3">/app/zk3/data/myid

启动zookeeper服务

/app/zk1/zookeeper/bin/zkServer.sh start

/app/zk2/zookeeper/bin/zkServer.sh start

/app/zk3/zookeeper/bin/zkServer.sh start

二、部署codis

1.go环境部署

cd /app

tar zxvf  go1.7.3.linux-amd64.tar.gz -C /app

mkdir  gopkg

配置GOROOT、GOPATH

vi /etc/profile

export GOROOT=/app/go

export GOPATH=/app/gopkg

export PATH=$PATH:$GOROOT/bin

生效环境变量

source /etc/profile

查看go版本

go version

go version go1.7.3 linux/amd64

2.codis编译

创建codis编译目录

mkdir -pv /app/gopkg/src/github.com/CodisLabs/

下载codis软件包

cd /app/gopkg/src/github.com/CodisLabs/

git clone https://github.com/CodisLabs/codis.git -b release3.2

编译

cd codis/

make

编译正确如下，没有错误出现说明已编译完成

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

##################################################

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                  :::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"
