mvzookeeper-3.4.6/usr/local/zookeeper
mkdir-p/data/zookeeper/{data,logs}
配置zoo.cfg
vim/usr/local/zookeeper/conf/zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/data/zookeeper/data
dataLogDir=/data/zookeeper/logs
clientPort=2181
server.1=zookeeper-1:
2888:
3888
server.2=zookeeper-2:
server.3=zookeeper-2:
上述配置内容说明，可以参考
http:
//zookeeper.apache.org/doc/trunk/zookeeperStarted.html#sc_RunningReplicatedZooKeeper
设置myid
在我们配置的dataDir指定的目录下面，创建一个myid文件，里面内容为一个数字，用来标识当前主机，conf/zoo.cfg文件中配置的server.X中X为什么数字，则myid文件中就输入这个数字
[root@zookeeper-1~]#echo1>
/data/zookeeper/data/myid
[root@zookeeper-2~]#echo2>
[root@zookeeper-3~]#echo3>
设置环境变量
vim/etc/profile
exportZOOKEEPERPATH=/usr/local/zookeeper
GO_BIN=/usr/local/go/bin
exportGOROOT=/usr/local/go
exportCODISPATH=/usr/local/codis
exportGOPATH=/data/gopath
exportGO15VENDOREXPERIMENT=1
exportPATH=$PATH:
$GOROOT/bin:
$ZOOKEEPERPATH/bin:
$CODISPATH/bin:
$GOPATH/bin
source/etc/profile
测试zoopkeeper
启动顺序zookeeper-1>
zookeeper-2>
zookeeper-3
[root@zookeeper-1zookeeper]#zkServer.shstart
JMXenabledbydefault
Usingconfig:
/usr/local/zookeeper/bin/../conf/zoo.cfg
Startingzookeeper...STARTED
[root@zookeeper-1zookeeper]#zkServer.shstatus
Mode:
leader
可以看到最先开始启动的是leader，其他两个是follower
注意关闭防火墙：
systemctlstopfirewalld.service
3、安装go语言环境
（参考：
cd/home/deploy/
wgetgo1.5.2.linux-amd64.tar.gz
tar-zxvfgo1.5.2.linux-amd64.tar.gz
4、安装codis
安装git
[root@vm-82-39-buy01-hp~]#yuminstall-ygit
配置环境变量
[root@vm-82-39-buy01-hp~]#vim/etc/profile
exportGOPATH=/home/deploy/gopath
exportCODISPATH=/usr/local/codis
exportPATH=/bin:
$PATH:
$GOPATH/bin:
$CODISPATH/bin
[root@vm-82-39-buy01-hp~]#source/etc/profile
[root@vm-82-39-buy01-hp~]#goget-u-d#这个需要几分钟下载共30M文件
cd$GOPATH/src/
make
makegotest
没有错误后
mkdir-p/home/deploy/codis/data/codis_server/{logs,conf,data}
mkdir-p/usr/local/codis/{logs,conf,scripts}
cp./config.ini/usr/local/codis/conf/
cp-rfbin/usr/local/codis/
5、配置运行codis
这是一个灰常麻烦的过程，要有心里准备
建立codis配置文件
viusr/local/codis/conf/config.ini（zookeeper-1配置）
coordinator=zookeeper
zk=10.154.82.106:
2181,10.154.82.107:
2181,10.154.82.108:
2181
product=codis-proxy
dashboard_addr=10.154.82.39:
18087
password=
backend_ping_period=5
session_max_timeout=1800
session_max_bufsize=131072
session_max_pipeline=1024
zk_session_timeout=30000
proxy_id=proxy_1
viusr/local/codis/conf/config.ini（zookeeper-2配置）
product=codis-proxy
dashboard_addr=10.154.82.107:
proxy_id=proxy_2
viusr/local/codis/conf/config.ini（zookeeper-3配置）
dashboard_addr=10.154.82.108:
proxy_id=proxy_3
建立codis-server服务配置文件
cdusr/local/codis/conf/
viredis.conf
daemonizeyes
pidfile/var/run/redis_6379.pid
port6379
tcp-backlog511

将redis.conf配置文件到其他codis集群机器上
6、启动顺序（三台服务器都需要启动）
A、启动zk
zkServer.shstart
B、启动codis
a、启动dashboard
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.inidashboard&
b、初始化slots
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.inislotsinit
c、启动codisredis
/usr/local/codis/bin/codis-server/data/codis_server/conf/6379.conf
/usr/local/codis/bin/codis-server/data/codis_server/conf/6380.conf
/usr/local/codis/bin/codis-server/data/codis_server/conf/6389.conf
/usr/local/codis/bin/codis-server/data/codis_server/conf/6390.conf
d、添加RedisServerGroup
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.iniserveradd0zookeeper-1:
6379master&
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.iniserveradd1zookeeper-1:
6380master&
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.iniserveradd2zookeeper-1:
6389master&
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.iniserveradd3zookeeper-1:
6390master&
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.iniserveradd0zookeeper-2:
6379slave&
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.iniserveradd1zookeeper-2:
6380slave&
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.iniserveradd2zookeeper-2:
6389slave&
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.iniserveradd3zookeeper-2:
6390slave&
e、分配slot
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.inislotrange-set03411online
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.inislotrange-set3426822online
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.inislotrange-set68310233online
f、启动codis-proxy
/usr/local/codis/bin/codis-proxy-c/usr/local/codis/conf/config.ini-L/data/log/codis-proxy.log--cpu=1--addr=0.0.0.0:
19000--http-addr=0.0.0.0:
11000&
g、上线proxy
/usr/local/codis/bin/codis-config-c/usr/local/codis/conf/config.iniproxyonlineproxy_1
h、测试
