Redis安装配置

Redis使用的端口号为6379，保证防火墙开启6379端口号。

安装过程：
[root@localhost ~]# tar -zxvf redis-4.0.1.tar.gz
[root@localhost ~]# cd redis-4.0.1
[root@localhost 4.0.1]# make
[root@localhost 4.0.1]# make PREFIX=/usr/local/redis install
# redis安装到 /usr/local/redis/目录下
[root@localhost 4.0.1]# mkdir -p /data/redisdb
# 创建redis数据存放目录

# 修改redis配置文件
[root@localhost 4.0.1]# cp ./redis.conf /usr/local/redis/
[root@localhost 4.0.1]# vim /usr/local/redis/redis.conf

将redis加入服务开机自启动
[root@localhost 4.0.1]# vim /etc/init.d/redis

# chkconfig: 2345 90 10
# de ion: service of redis for start and stop add by tomener

PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379
EXEC=/usr/local/redis/bin/redis-server
REDIS_CLI=/usr/local/redis/bin/redis-cli

PIDFILE=/var/run/redis_6379.pid
CONF=\"/usr/local/redis/redis.conf\"
AUTH=\"foobared\"
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 -a $AUTH -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

# 配置内核参数，等Redis脚本在重启或停止redis时，能提前同步数据到磁盘中（防止报错）
[root@localhost 4.0.1]# vim /etc/sysctl.conf
添加如下：
vm.overcommit_memory = 1
[root@localhost 4.0.1]# sysctl -p
[root@localhost 4.0.1]# chmod 0755 /etc/init.d/redis
[root@localhost 4.0.1]# chkconfig --add redis
[root@localhost 4.0.1]# chkconfig --level 235 redis on

# Redis的开启、关闭、重启
[root@localhost 4.0.1]# service redis start|stop|restart

安装phpredis扩展：
[root@localhost ~]# tar -zxvf redis-4.0.1.tgz
[root@localhost ~]# cd redis-4.0.1
[root@localhost redis-4.0.1]# /usr/local/php/bin/phpize
[root@localhost redis-4.0.1]# ./configure --with-php-config=/usr/local/php/bin/php-config
[root@localhost redis-4.0.1]# make 
[root@localhost redis-4.0.1]# make install

[root@localhost redis-4.0.1]# vim /usr/local/php/etc/php.ini
添加如下：
extension=\"redis.so\"

# 重启php-fpm
[root@localhost redis-4.0.1]# /etc/init.d/php7-fpm restart
