本文介绍了在CentOS 6.5环境下，如何配置和安装Codis集群。首先，需要安装Java和Go环境，然后详细讲述了Zookeeper的安装过程（存在错误），最后讲解了Codis的安装步骤。通过这些步骤，读者可以了解到在Linux系统中搭建Codis集群的基本流程。

环境

**
一、软件环境

系统：centos 6.5

Jdk：jdk-8u111-linux-x64.gz
go
zookeeper:
codis

本机IP：172.25.254.2
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

1安装java环境前面已经有文章不再赘述
2go环境安装
我下载的完整软件包不用编译直接加入变量即可
变量添加为

export GOROOT=/usr/local/go
export GOPATH=/usr/local/go/gopkg
export CODISPATH=/usr/local/codis
#export ZOOKEEPERPATH=/usr/local/zookeeper-3.4.8
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin:$CODISPATH/bin

这里写图片描述

zookeeper安装（有错误）





**

mkdir  /{app,appdata}

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

#autopurge.snapRetainCount=3

# Purge task interval in hours

# Set to "0" to disable autopurge feature

#autopurge.purgeInterval=1

server.1=172.25.254.1:2881:3888

server.2=172.25.254.2:2882:3888

server.3=172.25.254.3:2883:3888



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





查看zookeeper状态

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

JMX enabled by default

Using config:/app/zk1/zookeeper/bin/../conf/zoo.cfg

Mode: leader



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

JMX enabled by default

Using config:/app/zk2/zookeeper/bin/../conf/zoo.cfg



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

JMX enabled by default

Using config:/app/zk3/zookeeper/bin/../conf/zoo.cfg

Mode: follower

安装codis

cd  /usr/log/go/gopkg/src/github.com/CodisLabs/
mv  codis  .
make

看到如下结果即可
go build -i -o bin/codis-dashboard ./cmd/dashboard
go build -i -tags "cgo_jemalloc" -o bin/codis-proxy ./cmd/proxy
go build -i -o bin/codis-admin ./cmd/admin
go build -i -o bin/codis-fe ./cmd/fe

测试运行

codis-dashboard-admin.sh start
/usr/local/go/gopkg/src/github.com/CodisLabs/codis/admin/../config/dashboard.toml
starting codis-dashboard ...
