1 安装mysql

yum -y install mariadb-server
systemctl start mariadb.service
systemctl enable mariadb.service
mysql_secure_installation

　　默认安装的是5.5.40-MariaDB ，个人喜欢的版本，不再是5.1的那个了。

2 安装apache

yum install -y httpd
systemctl start httpd.service
systemctl enable httpd.service

apache 版本为 2.4.6

3 .安装php

yum -y install php
systemctl restart httpd.service

　　php5.4

其实安装和centos6的版本没啥区别。做了一些软件的升级，但是在启动上面，废弃了原先的/etc/init.d 下面的bash 脚本。而是用了systemctl 这个命令。

相关文件都在 /usr/lib/systemd/system 下面了。看了一下，比之前的bash 脚本简单好多。比如httpd的systemctl文件　　

cat /usr/lib/systemd/system/httpd.service 
[Unit]
Description=The Apache HTTP Server
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=notify
EnvironmentFile=/etc/sysconfig/httpd
ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND
ExecReload=/usr/sbin/httpd $OPTIONS -k graceful
ExecStop=/bin/kill -WINCH ${MAINPID}
# We want systemd to give httpd some time to finish gracefully, but still want
# it to kill httpd after TimeoutStopSec if something went wrong during the
# graceful stop. Normally, Systemd sends SIGTERM signal right after the
# ExecStop, which would kill httpd. We are sending useless SIGCONT here to give
# httpd time to finish.
KillSignal=SIGCONT
PrivateTmp=true

[Install]
WantedBy=multi-user.target

　　还是之前的chkconfig ，也集成在systemctl中了。很简洁 systemctl enable httpd

systemctl enable  httpd
ln -s ‘/usr/lib/systemd/system/httpd.service‘ ‘/etc/systemd/system/multi-user.target.wants/httpd.service‘

　　做的操作其实是一个软连接。很直观。操作什么直接反馈回来了。

[root@iZ23f0gpuenZ _local]# systemctl status  httpd

　　status 也做的很hi ，什么时候操作过httpd 的服务也一目了然。

　　centos 7 还做了进一步的升级，比如说加入了firewall ，内置了git 等，做了很实用的升级。更多功能正在摸索中。
