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
#

#

# 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
