Linux下Redis数据库的安装方法与自动启动脚本分享
作者：kevinhua
这篇文章主要介绍了Linux下Redis数据库的安装方法与自动启动脚本分享,自动启动脚本分别针对CentOS和Ubuntu系统来给出了编写示例,需要的朋友可以参考下
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
```ruby
#!/bin/sh
#
# redis - this script starts and stops the redis-server daemon
#
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
# processname: redis-server
# config: /etc/redis.conf
# config: /etc/sysconfig/redis
# pidfile: /var/run/redis.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

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
# Description: redis-server - Persistent key-value db
### END INIT INFO
DAEMON=/usr/local/bin/redis-server
DAEMON_ARGS=/etc/redis.conf

PIDFILE=/var/run/redis.pid
test -x $DAEMON || exit 0
test -x $DAEMONBOOTSTRAP || exit 0
set -e
case "$1" in
start)
echo -n "Starting $DESC: "
touch $PIDFILE
# chown redis:redis $PIDFILE
if start-stop-daemon —start —quiet —umask 007 —pidfile $PIDFILE —chuid redis:redis —exec $DAEMON — $DAEMON_ARGS
then
echo "$NAME."
else
echo "failed"
fi
;;
stop)
echo -n "Stopping $DESC: "
if start-stop-daemon —stop —retry 10 —quiet —oknodo —pidfile $PIDFILE —exec $DAEMON
then
echo "$NAME."
else
echo "failed"
fi
rm -f $PIDFILE
;;
restart|force-reload)
${0} stop
${0} start
;;
*)
echo "Usage: /etc/init.d/$NAME {start|stop|restart|force-reload}" >&2
exit 1

esac
exit 0
