Redis Centos6.5 安装以及开机启动脚本

一：安装Redis

1、下载源码，解压缩后编译源码

# wget http://download.redis.io/releases/redis-2.8.3.tar.gz # tar xzf redis-2.8.3.tar.gz
# cd redis-2.8.3
# make

2、进入安装目录的src文件夹下，有四个可执行文件redis-server、redis-benchmark、redis-cli和redis.conf,复制到同一个目录下

# mkdir /usr/redis
# cp redis-server  /usr/redis
# cp redis-benchmark /usr/redis
# cp redis-cli  /usr/redis
# cp redis.conf  /usr/redis
# cd /usr/redis

3、启动Redis服务。

# cd /usr/redis
# ./redis-server redis.conf

启动异常：

情况一：
[17496] 08 Oct 11:48:09.153 # Server started, Redis version 2.8.17

[17496] 08 Oct 11:48:09.153 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1'
for this to take effect.

[17496] 08 Oct 11:48:09.153 * The server is now ready to accept connections on port 6379

解决办法：编辑 /etc/sysctl.conf ， 添加一项
vm.overcommit_memory = 1，重启生效。

4、客户端测试。

redis 127.0.0.1:6379>  #显示此行意味着安装成功。

二：设置redis开机启动

环境：Linux-Centos6.6

1.编写启动脚本

注意：默认的redis.conf文件参数是前台启动的，修改daemonize no为daemonize yes则为后台启动。

     脚本的编码格式在window上编码放在linux可能不识别，可以用UltraEdit转换下格式“文件-->转换-->DOS 转 UNIX“

#!/bin/sh
#chkconfig: 345 86 14
#description: Startup and shutdown script for Redis

PROGDIR=/usr/redis #安装路径
PROGNAME=redis-server
DAEMON=$PROGDIR/$PROGNAME
CONFIG=/usr/redis/redis.conf
PIDFILE=/var/run/redis.pid
DESC="redis daemon"
SCRIPTNAME=/etc/rc.d/init.d/redis

start()
{
if test -x $DAEMON
then
echo -e "Starting $DESC: $PROGNAME"
if $DAEMON $CONFIG
then
echo -e "OK"
else
echo -e "failed"
fi
else
echo -e "Couldn't find Redis Server ($DAEMON)"
fi
}

stop()
{
if test -e $PIDFILE
then
echo -e "Stopping $DESC: $PROGNAME"
if kill `cat $PIDFILE`
then
echo -e "OK"
else
echo -e "failed"
fi
else
echo -e "No Redis Server ($DAEMON) running"
fi
}

restart()
{
echo -e "Restarting $DESC: $PROGNAME"
stop
start
}

list()
{
ps aux | grep $PROGNAME
}

case $1 in
start)
start
;;
stop)
stop
;;
restart)
restart
;;
list)
list
;;

*)
echo "Usage: $SCRIPTNAME {start|stop|restart|list}" >&2
exit 1
;;
esac
exit 0

把redis脚本文件放在 /etc/rc.d/init.d/ 目录下

2、增加服务并开机启动

# chmod +x /etc/rc.d/init.d/redis
# chkconfig --add redis
# chkconfig --level 345 redis on
# chkconfig --list redis

3、重启测试。
