Yum安装Apache(2.2)、MySQL(5.5)、PHP(5.4)_yum apache2.2

        CentOs装好后，先配置网络，进入 /etc/sysconfig/network-scripts/ifcfg-eth0，把onboot改为on，重启网络service network restart。

        更换Yum源

mv CentOS-Base.repo CentOS-Base.repo.bak
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
yum makecache
一定得把以前的 CentOS-Base.repo给删除了，不然在Yum操作的时候就会出现Repository base is listed more than once in the configuration提示信息

yum install httpd httpd-devel 
安装完成后，用/etc/init.d/httpd start 启动apache 
设为开机启动:chkconfig httpd on 

wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
rpm -ivh mysql57-community-release-el7-7.noarch.rpm
vim /etc/yum.repos.d/mysql-community.repo
把MySQL 5.5的enable改为1，其他版本的改为0
yum install mysql mysql-server mysql-devel
/etc/init.d/mysqld start
装好后，会出现Access denied for user 'root'@'localhost' (using password: YES)，解决方法如下
/etc/init.d/mysqld stop
mysqld_safe –skip-grant-tables &
mysql -uroot -p
use mysql;UPDATE user SET Password=PASSWORD(123456) WHERE USER='root';flush privileges;quit;
/etc/init.d/mysqld start

rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
yum install php54w  php54w-bcmath php54w-cli php54w-common  php54w-devel php54w-fpm    php54w-gd php54w-imap  php54w-ldap php54w-mbstring php54w-mcrypt php54w-mysql   php54w-odbc   php54w-pdo   php54w-pear  php54w-pecl-igbinary  php54w-xml php54w-xmlrpc php54w-opcache php54w-intl php54w-pecl-memcache

        重启apache，/etc/init.d/httpd restart，搞定。

        【update】下面是简单虚拟主机配置

#这里要关闭selinux，不然有时会报权限问题
vi /etc/sysconfig/selinux
SELINUX=disabled
reboot
 
#也可以临时关闭，但重启之后还是会变成原来的状态
setenforce 0

#如果重启Apache后，没有进入想要的界面，在错误日志里显示 Directory index forbidden by Options directive
 
rm -f /etc/httpd/conf.d/welcome.conf
rm -f /var/www/error/noindex.html
service httpd restart
