设置开启自启
<h4>Linux下Redis开机自启（Centos）</h4>
<p>1、设置redis.conf中daemonize为yes,确保守护进程开启。</p>
<p>2、编写开机自启动脚本</p>
<p><code>vi /etc/init.d/redis</code></p>
<p>脚本内容如下：</p>
<pre><code># chkconfig: 2345 10 90
# description: Start and Stop redis
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379
EXEC=/usr/redisbin/redis-server
REDIS_CLI=/usr/redisbin/redis-cli
PIDFILE=/var/run/redis.pid
CONF="/usr/redisbin/redis.conf"
AUTH="1234"
case "$1" in
start)
if [ -f $PIDFILE ]
then
echo "$PIDFILE exists, process is already running or crashed."
else
echo "Starting Redis server..."
$EXEC $CONF
fi
if [ "$?"="0" ]
then
echo "Redis is running..."
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE exists, process is not running."
else
PID=$(cat $PIDFILE)
echo "Stopping..."
$REDIS_CLI -p $REDISPORT SHUTDOWN
sleep 2
while [ -x $PIDFILE ]
do
echo "Waiting for Redis to shutdown..."
sleep 1
done
echo "Redis stopped"
fi
;;
restart|force-reload)
${0} stop
${0} start
;;
*)
echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
exit 1
esac</code></pre>
<h6>3、写完后保存退出VI</h6>
<h6>4、设置权限</h6>
<p><code>chmod 755 redis</code> 注：要在根目录/etc/init.d下使用</p>
<h6>5、启动测试</h6>
<p><code>/etc/init.d/redis start</code></p>
<p>启动成功会提示如下信息：</p>
<pre><code>Starting Redis server...
Redis is running...</code></pre>
<p>使用redis-cli测试：</p>
<pre><code>[root@rk ~]# /usr/redis/bin/redis-cli
127.0.0.1:6379> set foo bar
OK
127.0.0.1:6379> get foo
"bar"
127.0.0.1:6379> exit</code></pre>
<h6>6、设置开机自启动</h6>
<p><code>chkconfig redis on</code></p>
<h6>7、关机重启测试</h6>
<p><code>reboot</code></p>
<p>然后在用redis-cli测试即可。</p>

<p><code>/usr/local/redis/bin/redis-server /usr/local/redis/redis.conf</code></p>
<h5>卸载Redis</h5>
<p>1、首先查看redis-server是否启动 <code>ps aux | grep redis</code>
2、关闭这些进程 <code>kill -9 PID</code></p>

<p>从新配置的时候参考下这个
