CentOS7 编译安装Memcached、设置自启动、php7编译安装Memcached

环境：
VM+CentOS7+Linux+Nginx1.9.9+PHP7.1.6+Mysql5.7.17+Redis3.2.9

说明：在安装memcached之前要先安装libevent扩展，安装配置：./configure –prefix=/usr/local/libevent

一、下载安装包

> wget http://memcached.org/files/memcached-1.4.38.tar.gz

二、安装

1、解压

> cd /usr/local/tar> tar -zxvf memcached-1.4.38.tar.gz 

2、编译源程序

> cd memcached-1.4.38> ./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent> make && make install

3、启动memcached

> /usr/local/memcached/bin/memcached -m 64 -p 11211 -l 192.168.28.128 -u nobody -d

4、查看memcached进程

> ps -ef | grep memcached   #会显示进程号

5、停止memcache

> kill -9 进程号

6、设置memcache自启动

> vi /etc/init.d/memcached  # 新建memcached文件保存> cp /usr/local/tar/memcached-1.4.38/scripts/memcached.sysv /etc/init.d/memcached  #需要将脚本中的memcached目录改为自己的memcached目录即可> chmod 755 /etc/init.d/memcached  #修改文件权限> chkconfig --add memcached  #将memcache加入系统服务> chkconfig memcached on> service memcached start  #启动，也可以用/etc/init.d/memcached start

memcached文件内容如下：

#! /bin/sh## chkconfig: - 55 45# description:  The memcached daemon is a network memory cache service.# processname: memcached# config: /etc/sysconfig/memcached# Source function library.. /etc/rc.d/init.d/functionsPORT=11211USER=nobodyMAXCONN=1024CACHESIZE=64OPTIONS=""if [ -f /etc/sysconfig/memcached ];then    . /etc/sysconfig/memcachedfi# Check that networking is up.if [ "$NETWORKING" = "no" ]then    exit 0fiRETVAL=0prog="memcached"start () {    echo -n $"Starting $prog: "    # insure that /var/run/memcached has proper permissions    chown $USER /usr/local/memcached  # 此处有修改    daemon /usr/local/memcached/bin/memcached -d -p $PORT -u $USER  -m $CACHESIZE -c $MAXCONN -P  # 此处有修改 /usr/local/memcached/memcached.pid $OPTIONS    RETVAL=$?  # 此处有修改    echo    [ $RETVAL -eq 0 ] && touch /var/lock/subsys/memcached}stop () {    echo -n $"Stopping $prog: "    killproc memcached    RETVAL=$?    echo    if [ $RETVAL -eq 0 ] ; then        rm -f /var/lock/subsys/memcached        rm -f /usr/local/memcached/memcached.pid  # 此处有修改    fi}restart () {    stop    start}# See how we were called.case "$1" in    start)        start        ;;    stop)    stop    ;;    status)    status memcached    ;;    restart|reload)    restart    ;;    condrestart)    [ -f /usr/local/memcached ] && restart || : # 此处有修改    ;;    *)    echo $"Usage: $0 {start|stop|status|restart|reload|condrestart}"    exit 1esacexit $?

7、自启动

> systemctl memcached start  或者 /etc/init.d/memcached start

PHP安装memcached

1、安装libmemcached

> wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz > tar -zxvf libmemcached-1.0.18.tar.gz> cd libmemcached-1.0.18> ./configure> make && make install> ldconfig  # 最好执行一下，清除缓存

2、安装memcached

> yum -y install git  # 安装git,没有git，就安装git> git clone https://github.com/php-memcached-dev/php-memcached.git   # 下载> cd php-memcached  # 跑到里面去> git checkout php7  # 进入php7分支> /usr/local/php/bin/phpize   # 就是phpize是用来扩展php扩展模块的，通过phpize可以建立php的外挂模块。> ./configure --with-php-config=/usr/local/php/bin/php-config --disable-memcached-sasl> make && make install

3、修改php.ini

> vi /etc/php.ini   # 编辑php.ini，添加下面两行> extension_dir="/usr/local/php/lib/php/extensions/no-debug-zts-20100525/"" #(上面安装好的目录,看看有没有)> extension=memcached.so> /etc/init.d/php-fpm restart  # 重启php-fpm
