###安装 Redis

####(1) 下载 Redis

wget http://redis.googlecode.com/files/redis-2.2.11.tar.gz
tar xzvf redis-2.2.11.tar.gz

####(2) 编译并安装 Redis

make && make install

####(3) 复制并修改配置文件

cp redis.conf /etc/redis.conf
vi /etc/redis.conf

注意修改以下几项：

daemonize yes
loglevel warning
logfile /var/log/redis.log
maxmemory 2GB

(自行斟酌是不要开通 Virtual Memory 选项)

####(4) 设置 Redis-Server 自动启动服务

上网下载启动脚本 (gist.github.com，搜索redis init.d)，并简单修改

(至少需要修改redis、REDIS_CONF_FILE)

vi /etc/init.d/redisctl
chmod 755 redisctl
cp /etc/init.d/redisctl /etc/rc.d/init.d/redisctl \
&& ln -s /etc/init.d/redisctl /etc/rc.d/rc2.d/S90redisctl && ln -s /etc/init.d/redisctl /etc/rc.d/rc3.d/S90redisctl \
&& ln -s /etc/init.d/redisctl /etc/rc.d/rc4.d/S90redisctl && ln -s /etc/init.d/mongod /etc/rc.d/rc5.d/S90redisctl
chkconfig --add redisctl

(5) 重新启动后可以测试 redis-server 是否正常启动

```redis-cli set foo Bar redis-cli get foo

###Redis自动启动脚本 (CentOS 5.6适用)


```ruby
#!/bin/sh

###Redis 自动启动脚本 (Ubuntu 10.04 适用)

记得修改：

(1) —chuid group:user

(2) ln /etc/init.d/redisctl /etc/rc2.d/redisctl，重复rc3，rc4，rc5

启动脚本：

#! /bin/sh
### BEGIN INIT INFO
# Provides:             redis-server
# Required-Start:       $syslog
# Required-Stop:        $syslog
