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

Redis自动启动脚本

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
# Should-Start: $local_fs
# Should-Stop: $local_fs
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: redis-server – Persistent key-value db
