Linux下Redis数据库的安装方法与自动启动脚本分享

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
#

. /etc/sysconfig/network
# Check that networking is up.

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
NAME=redis-server
DESC=redis-server
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
