一、LNMP的安装

##先要下载,并根据不同系统进行安装:
wget -c http://soft.vpser.net/lnmp/lnmp1.3.tar.gz
tar zxvf lnmp1.3.tar.gz
cd lnmp1.3
./install.sh #开始进行安装操作

 

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:

常见lnmp管理命令:

#1.2版本以后,不需要再执行/root/lnmp了,可以在任意位置执行lnmp命令
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

 

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:

lnmp vhost add #执行lnmp添加网站命令
+-------------------------------------------+
|    Manager for LNMP, Written by Licess    |
+-------------------------------------------+
Please enter domain(example: www.lnmp.org): vpsmm.com #输入绑定的主域名
======================================
 Your domain: vpsmm.com
======================================
Do you want to add more domain name? (y/n) y #是否绑定其它域名
Enter domain name(example: lnmp.org *.lnmp.org): www.vpsmm.com #输入其它域名
domain list: www.vpsmm.com
Please enter the directory for the domain: vpsmm.com
(Default directory: /home/wwwroot/vpsmm.com): #默认创建的网站文件所在目录
Virtual Host Directory: /home/wwwroot/vpsmm.com
===========================
Allow Rewrite rule? (y/n)
===========================
y #是否添加伪静态文件
Please enter the rewrite of programme: 
wordpress,discuz,typecho,sablog,dabr rewrite was exist.
(Default rewrite: other):typecho #小夜用的typecho程序
===========================
You choose rewrite=typecho
===========================
===========================
Allow access_log? (y/n)
===========================
n #是否启用日志文件
======================================================
Create database and MySQL user with same name (y/n)
======================================================
y #是否创建mysql数据库
verify your current MySQL root password: **** #输入安装时的mysql数据库root密码
Warning: Using a password on the command line interface can be insecure.
MySQL root password correct.
Enter database name: vpsmm_user #创建数据库用户名
Your will create a database and MySQL user with same name: vpsmm_user
Please enter password for mysql user vpsmm_user: vpsmmpasswd
Your password: vpsmmpasswd #创建相应密码

Press any key to start create virtul host...

Rewrite: typecho
Enable log: no
Database username: vpsmm_user
Database userpassword: vpsmmpasswd
Database Name: vpsmm_user
Create ftp account: no
#以上为新创建网站的一些信息
================================================

 

 

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://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。

 

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)

 


常用命令

LNMP状态管理命令:

LNMP状态管理: /root/lnmp {start|stop|reload|restart|kill|status}
Nginx状态管理:/etc/init.d/nginx {start|stop|reload|restart}
