yum 安装apache php 使php支持memcached扩展

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

wget http://mirrors.hust.edu.cn/epel//6/x86_64/epel-release-6-8.noarch.rpm

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

 [webtatic]
 name=Webtatic Repository EL6 - $basearch
 baseurl=https://repo.webtatic.com/yum/el6/$basearch/     // 启用本机镜像地址
 #mirrorlist=https://mirror.webtatic.com/yum/el6/$basearch/mirrorlist    // 禁用网络镜像地址
 failovermethod=priority
 enabled=1    // 启用
 gpgcheck=0    // 注释掉
 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
