安装 Redis 2.6.14
- CentOS 5.4
- Redis 2.6.14
下载并安装：
$ wget http://redis.googlecode.com/files/redis-2.6.14.tar.gz
$ cd redis-2.6.14
$ make
$ sudo make install
CentOS 5自带的Tcl版本是8.4，Redis的make test需要用到Tcl 8.5以上的版本，如果你需要运行测试用例，请先安装新版本的Tcl，然后再安装Redis：
$ wget http://prdownloads.sourceforge.net/tcl/tcl8.6.0-src.tar.gz
$ tar xzvf tcl8.6.0-src.tar.gz
$ cd tcl8.6.0/unix
$ ./configure
$ make
$ make test
$ sudo make install

修复安装脚本 utils/install_server.sh 的问题

修正sudo的时候的环境变量 $PATH 的问题
默认的情况下，使用sudo命令时的$PATH环境变量只有/usr/bin:/bin两个路径，但是install_server.sh需要更多的路径：
chkconfig在/sbin目录下面redis-server和redis-cli默认安装在/usr/local/bin下面
所以我们必须修改sudo命令时的环境变量。我喜欢使用的方式是做一个alias，修改~/.bashrc文件：
alias sudo='sudo env PATH=/usr/bin:/bin:/sbin:/usr/sbin:/usr/local/bin'
重新登录以后就可以进行Redis服务的配置了！
配置 Master-Slave Replication
首先配置两个Redis实例，分别使用端口6379和6380，把目录安装在/data0/redis/6379和/data0/redis/6380下面：
$ cd utils
$ sudo ./install_server.sh

加入我们把 6379 作为 Master，把 6380 作为 Slave，我们只需要修改/etc/redis/6380.conf：
slaveof 127.0.0.1 6379
重启Slave即可完成一个Master-Slave集群的配置：
$ sudo service redis_6380 stop
$ sudo service redis_6380 start
测试 Master-Slave 集群
首先，连接到 Master 并写入数据：
$ redis-cli -p 6379
redis 127.0.0.1:6379> set hover-name Ruan
OK
然后连接到 Slave 测试是否能读取到数据，并尝试在 Slave 写数据：
$ redis-cli -p 6380
redis 127.0.0.1:6380> get hover-name
"Ruan"
redis 127.0.0.1:6380> set hover-name Hover
(error) READONLY You can't write against a read only slave.
OK，Master-Slave Replication 算是配置成功了！
