VpsPing教程:使用LNMP常见问题解答
一、LNMP的安装过程详解，注：绿色文字为注释，实际使用过程中没有。
##先要下载，并根据不同系统进行安装：wget -c http://soft.vpser.net/lnmp/lnmp1.0.tar.gztar zxvf lnmp1.0.tar.gzcd lnmp1.0./centos.sh #如果您是其它系统，则命令改为：./ubuntu.sh 或 debian.sh
以上为下载及进入安装过程，以下为安装前简易设置，切记输入个其它域名及牢记mysql密码：
=========================================================================LNMP V1.0 for CentOS/RadHat Linux VPS Written by Licess=========================================================================A tool to auto-compile & install Nginx+MySQL+PHP on LinuxFor more information please visit http://www.lnmp.org/====================================================================================================Please input the root password of mysql:(Default password: root):vpsmm.com #请输入mysql密码===========================MySQL root password:vpsmm.com======================================================Do you want to install the InnoDB Storage Engine?(Default no,if you want please input: y ,if not please press the enter button):INPUT error,The InnoDB Storage Engine will NOT install! #是否安装InnoDB===========================Install PHP 5.3.17,Please input yInstall PHP 5.2.17,Please input n or press Enter(Please input y or n):y #选择php版本You will install PHP 5.3.17===========================Install MySQL 5.5.27,Please input yInstall MySQL 5.1.60,Please input n or press Enter(Please input y or n):y #选择mysql版本You will install MySQL 5.5.27Press any key to start...or Press Ctrl+c to cancelCentOS release 6.3 (Final)#按任意键，设置完成，正式进入安装，预计20-40分钟完成
二，域名绑定详解
其实所谓的域名绑定，就是通过命令的形式，简易创建一个conf文件到/usr/local/nginx/conf/vhost下面，这个过程完全可以手工创建conf，或者，平时修改目录、域名等，直接修改conf文件，效果完全一样：
/root/vhost.sh #lnmp域名绑定命令
=========================================================================Add Virtual Host for LNMP V0.9 , Written by Licess=========================================================================LNMP is a tool to auto-compile & install Nginx+MySQL+PHP on LinuxThis script is a tool to add virtual host for nginxFor more information please visit http://www.lnmp.org/=========================================================================Please input domain:(Default domain: www.lnmp.org):legcloud.com #输入你要绑定的域名，legcould和www.legcloud要分别绑定===========================domain=legcloud.com===========================Do you want to add more domain name?

三、自定义伪静态规则
如果lnmp默认的伪静态规则不能满足你的需要，或者，你要自行定义伪静态规则，可以新建一个conf文件，放置于 /usr/local/nginx/conf 下，在域名配置文件，即：/usr/local/nginx/conf/vhost/legcloud.com.conf 里引用。
server{listen 80;server_name legcloud.com www.legcloud.com; #绑定的域名index index.html index.htm index.php default.html default.htm default.php; #首页文件root /home/legcloud.com; #网站存放目录include wordpress.conf; #伪静态规则文件，可自定义成你需要的location ~ .*.(php|php5)?${try_files $uri =404;fastcgi_pass unix:/tmp/php-cgi.sock;fastcgi_index index.php;include fcgi.conf;}location ~ .*.(gif|jpg|jpeg|png|bmp|swf)${expires 30d;}location ~ .*.(js|css)?${expires 12h;}access_log off;}
修改设置以后，一定要重新载入lnmp或者，重新载入nginx，以下任决命令都一样：
/root/lnmp reload #使用lnmp重新载入配置/etc/init.d/nginx reload #只重新载入nginx配置，我一般用这个
四、自定义404、503等常见错误
不管是404还是503等常见错误，还是设置/usr/local/nginx/conf/vhost/legcloud.com.conf文件来完成：
listen 80;server_name legcloud.com www.legcloud.com;index index.html index.htm index.php default.html default.htm default.php;root /home/legcloud.com;error_page 404 /404.php; #放在这里，可自定义文件名，再重载nginx就可以了include wordpress.conf;
五、判断当前域名并自动301到主域名
if ($host != 'vpsmm.com' ) {rewrite ^/(.*)$ http://vpsmm.com/$1 permanent;}#判断当前域名，如果不是则自动301到主域名，放置于error_page ...;上下均可。
六、关闭或开启FSO等php函数
lnmp最新版，默认禁用了一些函数，例如fso等，可修改/usr/local/php/etc/php.ini
disable_functions = passthru,exec,system,chroot,scandir....#----这是禁用函数，把不想禁用的删除即可----如果自用主机，最简单的修改方案：disable_functions =; passthru,exec,system,chroot,scandir....#----设置为全部开启
修改后，使用/etc/init.d/php-fpm restart，重新启动php
七、升级PHP和NGINX版本
cd lnm0.9 #进入lnmp安装目录./upgrade_nginx.sh #升级nginx，只要输入你要升级的版本即可（可见nginx.org）./upgrade_php.sh #升级php，只要输入你要升级的版本即可（可见php.net）
