##### 2.安装过程 #####

1).使用hadoop账号解压到/opt/目录下：

[hadoop@bgs-5p173-wangwenting software]$ tar -zxvf codis-${version}.tar.gz -C /opt

设置软连接

[hadoop@bgs-5p173-wangwenting software]$ tar -zxvf codis.tar.gz -C /opt
    [hadoop@bgs-5p173-wangwenting opt]$ ln -s codis-${version} codis

修改环境变量

[hadoop@bgs-5p173-wangwenting opt]$ vim /etc/profile
    添加以下内容：
    export GOROOT=/opt/codis/go
    export PATH=${GOROOT}/bin:$PATH
    export GOPATH=/opt/codis/codis

使环境变量生效：

[hadoop@bgs-5p173-wangwenting opt]$ source /etc/profile

2).编译

[hadoop@bgs-5p173-wangwenting opt]$ cd /opt/codis/codis/src/github.com/wandoulabs/codis/
    [hadoop@bgs-5p173-wangwenting codis]$ mv bin/redis* ../                           //把redis相关的conf文件移动到上一层，避免编译时被删除
    注释bootstrap.sh文件中的go get开头的命令并编译:
    [hadoop@bgs-5p173-wangwenting codis]$ ./bootstrap.sh                             //编译
    [hadoop@bgs-5p173-wangwenting codis]$ mv ../redis*  bin/                         //移回redis相关的conf文件

    bind 172.24.5.173
    logfile "/opt/codis/codis/src/github.com/wandoulabs/codis/logs/redis6479.log"
    dbfilename "dump6479.rdb"
    appendfilename "appendonly6479.aof"
    dir "/opt/codis/codis/src/github.com/wandoulabs/codis/data"
