使用LNMP常見問題解答

1、LNMP的安裝過程詳解，注：綠色文字爲註釋，實際使用過程當中沒有。

##先要下載，並根據不一樣系統進行安裝：

wget -c http://soft.vpser.net/lnmp/lnmp1.0.tar.gz

tar zxvf lnmp1.0.tar.gz

cd lnmp1.0

./centos.sh #若是您是其它系統，則命令改成：./ubuntu.sh 或 debian.sh

以上爲下載及進入安裝過程，如下爲安裝前簡易設置，切記輸入個其它域名及牢記mysql密碼：

二，域名綁定詳解

其實所謂的域名綁定，就是經過命令的形式，簡易建立一個conf文件到/usr/local/nginx/conf/vhost下面，這個過程徹底能夠手工建立conf，或者，平時修改目錄、域名等，直接修改conf文件，效果徹底同樣：

/root/vhost.sh #lnmp域名綁定命令

For more information please visit http://www.lnmp.org/

=========================================================================

Please input domain:

(Default domain: www.lnmp.org):legcloud.com #輸入你要綁定的域名，legcould和www.legcloud要分別綁定

===========================

domain=legcloud.com

===========================

Do you want to add more domain name? (y/n)

y #是否添加子域名，能夠輸入y或n，這裏輸入y

Type domainname,example(bbs.vpser.net forums.vpser.net luntan.vpser.net):

www.legcloud.com #輸入你要綁定的其它域名，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 #網站存放目錄，可默認或自行輸入

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

3、自定義僞靜態規則

若是lnmp默認的僞靜態規則不能知足你的須要，或者，你要自行定義僞靜態規則，能夠新建一個conf文件，放置於 /usr/local/nginx/conf 下，在域名配置文件，即：/usr/local/nginx/conf/vhost/legcloud.com.conf 裏引用。

server

{

listen       80;

server_name legcloud.com www.legcloud.com; #綁定的域名

index index.html index.htm index.php default.html default.htm default.php; #首頁文件

root  /home/legcloud.com; #網站存放目錄

include wordpress.conf; #僞靜態規則文件，可自定義成你須要的

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;

}

修改設置之後，必定要從新載入lnmp或者，從新載入nginx，如下任決命令都同樣：

/root/lnmp reload #使用lnmp從新載入配置

/etc/init.d/nginx reload #只從新載入nginx配置，我通常用這個

4、自定義40四、503等常見錯誤

無論是404仍是503等常見錯誤，仍是設置/usr/local/nginx/conf/vhost/legcloud.com.conf文件來完成：

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; #放在這裏，可自定義文件名，再重載nginx就能夠了

include wordpress.conf;

5、判斷當前域名並自動301到主域名

if ($host != 'vpsmm.com' ) {rewrite ^/(.*)$ http://www.vpsmm.com/$1 permanent;}

#判斷當前域名，若是不是則自動301到主域名，放置於error_page ...;上下都可。

6、關閉或開啓FSO等php函數

lnmp最新版，默認禁用了一些函數，例如fso等，可修改/usr/local/php/etc/php.ini

disable_functions = passthru,exec,system,chroot,scandir....

#----這是禁用函數，把不想禁用的刪除便可----若是自用主機，最簡單的修改方案：

disable_functions =

; passthru,exec,system,chroot,scandir....

#----設置爲所有開啓

修改後，使用/etc/init.d/php-fpm restart，從新啓動php

7、升級PHP和NGINX版本

cd lnm0.9 #進入lnmp安裝目錄

./upgrade_nginx.sh #升級nginx，只要輸入你要升級的版本便可（可見nginx.org）

./upgrade_php.sh #升級php，只要輸入你要升級的版本便可（可見php.net）
