篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了yum 安装apache php 使php支持memcached扩展相关的知识,希望对你有一定的参考价值。

    在公司上新项目的时候,无论生产环境还是测试环境,都会让运维安装php 环境(lamp/lnmp),并让php支持memcached 的扩展。这里搭建php环境其实主要就是搭建apache 和php。mysql一般都是用单独的数据库,不会再同一台服务器上的。看似简单的东西,在搭建的时候,还真是遇到了不少问题,以此记录,方便各位运维同学。

 

一.163和默认的镜像源有些包不能下载,使用阿里的镜像源

见本博客地址:http://www.cnblogs.com/lzcys8868/p/7532569.html

 

二. 必须安装webtatic库

Centos 5.X
  rpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm
 
CentOs 6.x
 rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
 
CentOs 7.X
 rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
 rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
 
 
三. yum 安装httpd及其扩展
1.安装httpd及其扩展
yum –y install httpd  httpd-devel
yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql
 
2.设置开机启动Apache
chkconfig --levels 235 httpd on
 
3.启动Apache
service httpd start

 

四. 安装php5.5版本. php要求使用5.5。yum 默认安装的是php5.3
1.安装php5.5
yum -y install php55w.x86_64 php55w-cli.x86_64 php55w-common.x86_64 php55w-gd.x86_64 php55w-ldap.x86_64 php55w-mbstring.x86_64 php55w-mcrypt.x86_64 php55w-mysql.x86_64 php55w-pdo.x86_64 php55w-devel
 
报错:Error: Package: php55w-mcrypt-5.5.38-1.w6.x86_64 (webtatic)
           Requires: libmcrypt.so.4()(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

 

 

2.错误提示缺少libmcrypt.so这个库。安装libmcrypt,libmcrypt-deve
rpm -ivh epel-release-6-8.noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
yum -y install libmcrypt libmcrypt-devel

 

 3.在重新安装php5.5
 
4.安装php-fpm5.5 模块
yum -y install php55w-fpm php55w-common
注:如果yum 不能安装,修改webtatic.repo 镜像源地址
[root@localhost phpredis-develop]# vim /etc/yum.repos.d/webtatic.repo
1 [webtatic]
2 name=Webtatic Repository EL6 - $basearch
3 baseurl=https://repo.webtatic.com/yum/el6/$basearch/     // 启用本机镜像地址
4 #mirrorlist=https://mirror.webtatic.com/yum/el6/$basearch/mirrorlist    // 禁用网络镜像地址
5 failovermethod=priority
6 enabled=1    // 启用
7 gpgcheck=0    // 注释掉
8 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-webtatic-el6

在次重新yum 安装 php55w-fpm   php55w-common

 

五. 先搭建memcached 服务端,见本博客地址:http://www.cnblogs.com/lzcys8868/p/7532615.html
   安装包使用如下版本
   memcached 服务端安装包:
      memcached-1.4.0.tar.gz   libevent-2.0.22-stable.tar.gz
 
   php支持memcached 扩展安装包:
      memcached-2.2.0.tgz     libmemcached-1.0.18.tar.gz

六. php扩展memcached
php的扩展memcache,不支持cas,所以我们要装memcached扩展,memcached扩展是基于libmemcached,所以要先安装libmemcached
 
[root@localhost soft]# ls
memcached-1.4.0.tar.gz
libevent-2.0.22-stable.tar.gz  memcached-2.2.0.tgz
libmemcached-1.0.18.tar.gz    
[root@localhost soft]#tar xf libmemcached-1.0.18.tar.gz -C /usr/src
[root@localhost soft]# cd /usr/src/libmemcached-1.0.18/
[root@localhost libmemcached-1.0.18]#  ./configure --prefix=/usr/local/libmemcached --with-memcached=/usr/local/memcached/bin/memcached  
[root@localhost libmemcached-1.0.18]# make && make install
[root@localhost libmemcached-1.0.18]# cd /root/soft/
[root@localhost soft]# tar xf memcached-2.2.0.tgz -C /usr/src/
[root@localhost soft]# cd /usr/src/memcached-2.2.0/
[root@localhost memcached-2.2.0]# /usr/bin/phpize
[root@localhost memcached-2.2.0]# ./configure --with-php-config=/usr/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached
 
error1: no, sasl.h is not available. Run configure with –disable-memcached-sasl to disable this check

 如果报errro1 的错误,根据引导执行

[root@localhost memcached-2.2.0]# ./configure --with-php-config=/usr/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached --disable-memcached-sasl --with-zlib-dir
 
error2: memcached support requires ZLIB. Use --with-zlib-dir=<DIR> to specify the prefix where ZLIB headers and library are located
如果报error2的错误,根据如下方法解决
yum install libmemcached libmemcached-devel
yum install zlib zlib-devel

 

报错解决之后,编译安装

[root@localhost memcached-2.2.0]# make && make install   //出现如下行,说明编译安装正确
Installing shared extensions:        /usr/lib64/php/modules/
[root@localhost memcached-2.2.0]# vim /etc/php.ini    //在最后加入
extension=memcached.so
[root@localhost memcached-2.2.0]# php -m | grep memcached    //查看是否有memcached扩展
memcached
 

 

以上是关于yum 安装apache php 使php支持memcached扩展的主要内容,如果未能解决你的问题,请参考以下文章

php源码安装,并配置apache支持php

编译安装最新版PHP,支持apache24,支持workman
