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.gz
tar zxvf lnmp1.0.tar.gz
cd 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：

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

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
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;
if ($host != ‘vpsmm.com‘ ) {rewrite ^/(.*)$ http://www.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。
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）
