Linux下Redis的安装配置

环境： centos7  PHP7

1.切到准备安装的目录

cd /usr/local

2.下载Redis

wget http://download.redis.io/redis-stable.tar.gz

3.解压

tar -zxf redis-stable.tar.gz

4.编译

make

5.休息十秒钟

6.进入src目录

cd src

7.编译检查

make test

8.安装

make install

9.切到外层将目录改名

cd /usr/local

mv redis-stable redis

10.修改配置

vi redis/redis.conf

搜索daemonize 改为  daemonize yes  （是否守护进程）

搜索pidfile 改为 pidfile /usr/local/redis/redis.pid

搜索logfile 改为 logfile /usr/local/redis/redis.log

搜索save 60 10000  改为 save 60 1000

搜索#maxmemory <bytes>  改为 maxmemory 256M （最大允许使用内存）

远程连接配置：

 bind 127.0.0.1 改为  #bind 127.0.0.1 (注释掉)

 protected-mode yes 改为 protected-mode no

 requirepass yourpassword （密码）

11.启动Redis

/usr/local/redis/src/redis-server

12.开机启动

vi /etc/init.d/redis

输入以下内容  路径换成实际路径：

#!/bin/bash
# chkconfig: 2345 10 90
# description: Start and Stop redis

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

PIDFILE=/usr/local/redis/redis.pid
CONF="/usr/local/redis/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

保存退出:wq

给个权限：chmod 755 /etc/init.d/redis

13.开启服务

/etc/init.d/redis start

如果看到以下信息则成功
Starting Redis server...
Redis is running...

14.启动客户端：

/usr/local/redis/src/redis-cli 

用一下set get

存储数据正常  

15.设置开机自启

chkconfig redis on

安装Redis扩展

16.下载地址:

https://github.com/phpredis/phpredis

用ftp传到Linux  (或者是右键点击 Download ZIP 按钮 复制链接 使用wget直接下载)

17.移动到准备安装的目录

mv develop.zip /usr/local/develop.zip

18.解压

unzip develop.zip

19.进入目录中

cd phpredis-develop

20.执行PHP安装目录下的phpize

/usr/local/php7/bin/phpize

21.报错信息：

Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

解决办法：

yum install m4
yum install autoconf

再次执行phpize：

/usr/local/php7/bin/phpize

22.搜索php-config路径

find /usr/local/php7/ -name php-config
得到/usr/local/php7/bin/php-config

23.配置

./configure --with-php-config=/usr/local/php7/bin/php-config

24.编译

make

25.安装

make install

出现如下结果：

26.编辑php.ini

vi /usr/local/php7/etc/php.ini

在一排extension的地方加入：
extension=redis.so

27.重启Apache

systemctl restart httpd

若是Nginx

杀掉php-fpm进程

ps -ef | grep php-fpm

kill -9 ***

重新启动php-fpm

/usr/local/php7/sbin/php-fpm -c /usr/local/php7/etc/php.ini

28.新建PHP文件运行phpinfo()

搜索有无Redis扩展

29.运行以下代码 如果存取正常 则安装成功

$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$redis->set("name", "hello world");
echo $redis->get("name");
