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.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：
========================================================================= LNMP V1.0 for CentOS/RadHat Linux VPS Written by Licess ========================================================================= A tool to auto-compile & install Nginx+MySQL+PHP on Linux For 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 y Install 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 y Install 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 5.5.27 Press any key to start...or Press Ctrl+c to cancel CentOS 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 Linux This script is a tool to add virtual host for nginx For 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? (y/n) y #是否添加子域名，可以输入y或n，这里输入y Type domainname,example(bbs.vpser.net forums.vpser.net luntan.vpser.net): www.legcloud.com #输入你要绑定的其它域名，支持泛解析，例如：*.legcloud.com =========================== domain list=www.legcloud.com =========================== Please input the directory for the domain:legcloud.com : (Default directory: /home/wwwroot/legcloud.com):/home/legcloud.com #网站存放目录，可默认或自行输入 =========================== Virtual Host Directory=/home/legcloud.com =========================== =========================== Allow Rewrite rule? (y/n) =========================== y #是否添加伪静态规则，这里输入是 Please input the rewrite of programme : wordpress,discuz,typecho,sablog,dabr rewrite was exist. (Default rewrite: other):wordpress #输入wordpress就可以 =========================== You choose rewrite=wordpress =========================== =========================== Allow access_log? (y/n) =========================== n #是否创建日志文件，如果不需要可不用 Press any key to start create virtul host... #按任意建继续，以下为一些相关信息，包括创建目录，测试nginx等，如果有错误提示，请一定要认真分析 Create Virtul Host directory...... set permissions of Virtual Host directory...... You select the exist rewrite rule:/usr/local/nginx/conf/wordpress.conf Test Nginx configure file...... nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful Restart Nginx...... ========================================================================= Add Virtual Host for LNMP V0.9 , Written by Licess ========================================================================= For more information please visit http://www.lnmp.org/ Your domain:legcloud.com Directory of legcloud.com:/home/legcloud.com =========================================================================
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----如果自用服务器，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）
