搭建LNAMP环境(七)- PHP7源码安装Memcached和Memcache拓展
上一篇:搭建LNAMP环境(六)- PHP7源码安装MongoDB和MongoDB拓展
一、安装Memcached
1.yum安装libevent事件触发管理器
yum -y install libevent-devel
2.创建memcached用户组和用户
groupadd memcached
useradd -r -g memcached -s /sbin/nologin -M memcached
3.下载memcached源码包,并将源码包放到/usr/local/src/目录下
下载页面:http://memcached.org/downloads
这里用的是 memcached-1.4.33.tar.gz
下载地址:http://memcached.org/files/memcached-1.4.33.tar.gz
4.进入src/目录
cd /usr/local/src/
5.解压源码包
tar -zxf memcached-1.4.33.tar.gz
6.进入memcached源码目录,编译安装
cd memcached-1.4.33/ ./configure --prefix=/usr/local/memcached --with-libevent make && make install
7.修改memcached目录权限
chown -R memcached:memcached /usr/local/memcached
8.将memcached命令加入环境变量,修改profile文件
vim /etc/profile
9.修改为下面内容,保存退出
PATH=/usr/local/mysql/bin:/usr/local/php/bin:/usr/local/redis/bin:/usr/local/mongodb/bin:/usr/local/memcached/bin:$PATH
10.使/etc/profile里的配置立即生效
source /etc/profile
11.将memcached服务脚本加入到init.d/目录,创建memcached文件
vim /etc/init.d/memcached
12.加入下面内容,保存退出
#!/bin/sh # # memcached: MemCached memcached # # chkconfig: - 90 25 # description: MemCached memcached # # Source function library. . /etc/rc.d/init.d/functions . /etc/sysconfig/network start() { echo -n $"Starting memcached: " /usr/local/memcached/bin/memcached -d -u memcached -m 1024 -l 127.0.0.1 -p 11211 echo } stop() { echo -n $"Shutting down memcached: " killproc memcached echo } [ -f /usr/local/memcached/bin/memcached ] || exit 0 # See how we were called. case "$1" in start) start ;; stop) stop ;; restart|reload) stop start ;; condrestart) stop start ;; *) echo $"Usage: $0 {start|stop|restart|reload|condrestart}" exit 1 esac exit 0
参数解释:
/usr/local/bin/memcached -d -u memcached -m 1024 -l 127.0.0.1 -p 11211 -c 1024 -P /var/run/memcached/memcached.pid
-d 启动一个守护进程。可以启动多个守护进程,但是端口不能重复
-u 运行Memcache的用户
-m 分配的内存数量,单位是MB
-l 监听的服务器IP地址,默认是本机
-p 监听的端口
-c 最大运行的并发连接数,默认是1024
-P pid文件位置
13.为memcached添加可执行权限
chmod +x /etc/init.d/memcached
14.将memcached加入系统服务
chkconfig --add memcached
15.修改服务的默认启动等级
chkconfig memcached on
16.启动memcached
service memcached start
二、PHP7安装Memcache拓展
1.yum安装zip
yum install -y zip unzip
2.下载php7 memcache拓展包,并将源码包放到/usr/local/src/目录下
下载地址:https://codeload.github.com/websupport-sk/pecl-memcache/zip/php7/pecl-memcache-php7.zip
3.进入src/目录
cd /usr/local/src/
4.解压拓展包
unzip pecl-memcache-php7.zip
5.进入memcache拓展目录,编译安装拓展
cd pecl-memcache-php7 phpize ./configure --with-php-config=/usr/local/php/bin/php-config make && make install
6.修改php.ini文件
vim /usr/local/php/etc/php.ini
7.添加memcache.so扩展配置,保存退出
extension=memcache.so
8.重启Apache或php-fpm
service httpd restart
service php-fpm restart
9.在web目录下添加php文件,如/usr/local/apache/htdocs/memcache.php 或 /usr/local/nginx/html/memcache.php
<?php $memcache = new Memcache; $memcache->connect('127.0.0.1', 11211) or die ("Could not connect"); $memcache->set('class','toefl'); print_r($memcache->get('class'));
访问URL,如:http://192.168.8.9/memcache.php
页面显示正常,则配置成功
Memcached安装完毕
