1 安装go1.3.1 CentOS 7.0 安装go 1.3.1
1.1 下载go安装包 golang中国上下载 下载到Downloads下
1.2 解压 tar -zxf go1.3.1.linux-amd64.tar.gz -C /usr/local/
1.3 修改 etc/profile 文件在文件后加入 export的几行,在unset下面直接加,不要有空行
unset i
unset -f pathmunge
export GOROOT=/usr/local/go
export PATH=$GOROOT/bin:$PATH
export GOPATH=/data/gopkg
1.4 然后执行 source /etc/profile 刷新配置文件
1.5 运行命令 go 测试go是否安装成功
1.6 在usr/local/go/test 下 运行 go run helloworld.go 测试
2 安装git yum -y install git
3 配置hosts文件 3个机器都是相同的配置
cd /etc
vi hosts
[will@weiguoyuan etc]$ more hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.64.4.57 weiguoyuan
10.64.4.95 weiguoyuan2
10.64.4.99 hemy
还需要配置windows下的hosts文件 否则在windows下的jodis客户端访问codis集群机器找不到主机名对应的ip
C:\Windows\System32\drivers\etc
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a ‘#‘ symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
10.64.4.57 weiguoyuan
10.64.4.95 weiguoyuan2
10.64.4.99 hemy
4 安装zookeeper 集群 3个机器上每个机器上都安装一个zookeeper
4.1 官网下载 下载到Downloads下
4.2 tar -xzf zookeeper.**.tar.gz -C /usr/local
4.3 cd /usr/local/zookeeper*/conf
4.4 cp zookeeper.cfg zoo.cfg
4.5 vi zoo.cfg(三个zookeeper的配置文件相同) 在尾部加上节点信息 (节点之前通信)
[will@weiguoyuan conf]$ more 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 an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=10.64.4.57:2888:3888
server.2=10.64.4.95:2888:3888
server.3=10.64.4.99:2888:3888
4.6 配置zookeeper节点id
先启动3个机器的zookeeper zookeeper会自动生成/tmp/zookeeper文件夹
再设置节点的myid myid对应的zoo.cfg的server.ID比如192.168.253.128机器上的myid文件内容为1(3个机器分别生成123
echo "1" >/tmp/zookeeper/myid #3个机器上分别执行
echo "2" >/tmp/zookeeper/myid
echo "3" >/tmp/zookeeper/myid
4.7 启动zookeeper
cd /usr/local/zookeeper/bin
./zkServer.sh start
./zkServer.sh stop
./zkServer.sh status 查看节点状态有 leader,fellower
5 安装codis 编译 3个机器上都需安装
go get -d github.com/wandoulabs/codis
cd $GOPATH/src/github.com/wandoulabs/codis
./bootstrap.sh (这步比较慢 失败了可以重试)
make gotest

1 启动3个机器
2 关闭3个机器防火墙
CentOS防火墙分为2中 firewalld 和 iptables
如果是firewalld systemctl stop firewalld.service
如果是iptables systemctl stop iptables.service
3 启动3个机器的zookeeper
cd /usr/local/zookeeper/bin
./zkServer.sh start
4 在没有配置add_group.sh的两个机器上(机器2和3)
cd /data/gopkg/src/github.com/wandoulabs/codis/sample
./start_redis.sh
5 在配置add_group.sh的机器上(机器1) 上
cd /data/gopkg/src/github.com/wandoulabs/codis/sample
./startall.sh
6 在机器1上打开火狐浏览器 打开网址 http://localhost:18087/admin 可以看到节点 代理信息
7 在机器2和3上分别启动代理
cd /data/gopkg/src/github.com/wandoulabs/codis/sample
./start_proxy.sh
8 在机器1上浏览器http://localhost:18087/admin的代理信息中 设置proxy_2 proxy_3 online
9 可以通过windows上的jodis客户端访问Codis集群了
