14、codis的安装

1.基本信息

版本	2.0
安装机器	三台机器
账号	hadoop
源路径	/opt/software/codis-2.0.tar.gz
目标路径	/opt/codis -> opt/codis-2.0
依赖关系	无

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

[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
