部署PHP结合apache
1.解决PHP安装的依赖开发环境
yum install -y zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libtool-ltdl-devel pcre pcre-devel apr apr-devel zlib-devel gcc make
2.安装PHP，以及PHP连接MysqL数据库的驱动
[root@zhanghuan ~]# yum install PHP PHP-fpm PHP-MysqL -y
3.PHP不需要额外修改，但是需要修改apache配置文件，支持PHP的脚本读取即可
# PHP程序和apache结合工作
4.编辑apache配置文件
vim /etc/httpd/conf/httpd.conf
5.进行配置文件修改
# 使用vim，显示行号 :set nu
# 在120行左右这里，添加如下配置
119 DocumentRoot "/var/www/html"
120 TypesConfig /etc/mime.types
121 AddType application/x-httpd-PHP .PHP
122 AddType application/x-httpd-PHP-source .PHPs
123 DirectoryIndex index.PHP index.html
6.编写一个PHP的脚本，看apache是否能正确加载读取
# 这个脚本需要放置在如下位置
vim /var/www/html/index.PHP
<Meta charset=utf8>
我是新的首页，你好兄弟们
<?PHP
PHPinfo();
?>
7.重启apache
[root@zhanghuan ~]# systemctl restart httpd
[root@zhanghuan ~]#
部署一个论坛disuz
# 下载论坛的压缩代码
wget http://download.comsenz.com/discuzX/3.2/discuz_X3.2_SC_UTF8.zip
# 2.解压缩代码包，使用解压命令 unzip
yum install unzip -y
# 3.解压缩
# 4.拷贝upload代码到apache目录下，即可访问
[root@zhanghuan discuz]# cp -r upload/* /var/www/html/
cp: overwrite ‘/var/www/html/index.PHP’? y
# 5.修改代码权限
[root@zhanghuan discuz]# chmod -R 777 /var/www/html/*
