lnmp #会出现一些提示信息
lnmp restart #重启
lnmp vhost add #添加网站绑定
lnmp database add #添加数据库信息
四，域名绑定：
lnmp vhost add #执行lnmp添加网站命令

五、自定义伪静态规则
如果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/maizim.com.conf 里引用。
server
{
listen 80;
server_name maizim.com www.maizim.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，重新载入nginx，或者重新载入lnmp，效果是一样的：
只重新载入nginx配置
/etc/init.d/nginx reload
或者lnmp整个重新载入配置
/root/lnmp reload
六、自定义404、503等常见错误
</blockquote>
不管是404还是503等常见错误，还是设置/usr/local/nginx/conf/vhost/maizim.com.conf文件来完成：
listen 80;
server_name maizim.com www.maizim.com;
index index.html index.htm index.php default.html default.htm default.php;
root /data/webroot/maizim.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 typecho.conf;
七、判断当前域名并自动301到主域名
if ($host != ‘maizim.com‘ ) {rewrite ^/(.*)$ http://www.maizim.com/$1 permanent;}
八、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, 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
九、升级PHP和NGINX版本
升级nginx，只要输入你要升级的版本即可（可见nginx.org）
cd lnm0.9 #进入lnmp安装目录
./upgrade_nginx.sh
升级php，只要输入你要升级的版本即可（可见php.net）
./upgrade_php.sh
