【人麻了】centos6.5更换yum源+httpd安装+php56安装+执行shell无写入权限+卸载php-526互联

平常都是用宝塔部署web测试环境，今天需要手动去给客户部署php项目运行环境。而且居然还是centos6.5的老系统了，我整个人都麻了...

更换yum源

为啥我人麻了？？？

报错：centos6 yum安装软件报错Cannot retrieve repository metadata (repomd.xml) for repository: epel 的解决办法
原因分析：官方已经停止更新centos6相关的源，可以使用其他源替代

/etc/yum.repos.d/CentOS-Base.repo修改为

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

执行

yum clean all
yum makecache

安装httpd

yum -y install httpd*

修改一下 /etc/httpd/conf/httpd.conf 配置文件，

#ServerName www.example.com:80

更改为

ServerName localhost:80

Listen 80 #这个表示默认端口是80端口，可以修改成别的

然后重启 httpd

service httpd restart

通过ip:端口号，访问即可

默认web目录在 /var/www/html 目录下

php56安装

此时你通过yum安装的php是5.3版本的，远古时代的php，我就不多说了。。。
我们需要追加CentOS 6.5的epel及remi源。

# rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

以下是CentOS 7.0的源。(这条忽略，我顺便记录下)

# yum install epel-release
# rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

使用yum list命令查看可安装的包(Packege)。（也可以忽略，不用执行也行）

# yum list --enablerepo=remi --enablerepo=remi-php56 | grep php

yum源配置好了，下一步就安装PHP5.6。

yum install --enablerepo=remi --enablerepo=remi-php56 php php-opcache php-devel php-mbstring php-mcrypt php-mysqlnd php-phpunit-PHPUnit php-pecl-xdebug php-pecl-xhprof

安装完成后，使用php -v，查看版本号即可。
