ubuntu14.04配置lnmp

看到了一片讲解ubuntu下安装lnmp的文章，跟着一步步的来，竟然很顺利的成功了，将文章复制如下，原著勿怪

一、操作步骤
 
1.安装Nginx
 
sudo apt-get install update
sudo apt-get install nginx
2.测试Nginx，如果显示如下图则代表安装成功
 
ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//' #查看本机IP地址
curl http://127.0.0.1 或者 curl http://本机ip
curl nginx
 
3.安装MySQL
 
sudo apt-get install mysql-server
# 连续输入两次相同的密码
4.安装PHP
 
sudo apt-get install php5-fpm php5-mysql
5.配置PHP，修改php.ini文件
 
# 备份php.ini文件
cp /etc/php5/fpm/php.ini /etc/php5/fpm/php.ini.back
# 取消有安全隐患的pathinfo模式
vim /etc/php5/fpm/php.ini
# 将cgi.fix_pathinfo=1 设置为 cgi.fix_pathinfo=0
cgi.fix_pathinfo=0
#启动php-fpm
sudo service php5-fpm restart
6.配置Nginx让其使用php-fpm进程
 
#备份/etc/nginx/sites-available/default文件
cp /etc/nginx/sites-available/default /etc/nginx/sites-available/default.back
#修改defalut文件内容如下
server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;
 
    root /usr/share/nginx/html;
    index index.php index.html index.htm;
 
    server_name server_domain_name_or_IP;
 
    location / {
        try_files $uri $uri/ =404;
    }
 
    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }
 
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}
7.重启nginx服务器
 
sudo service nginx restart
8.在/usr/share/nginx/html/里面建立info.php写入如下内容
 
<?php
	phpinfo();
?>
浏览器输入: http://ip/info.php
phpinfo显示
 
二、写在最后
 
这篇文章只是简单的介绍了Nginx+php-fpm的安装。如果你对Linux有更深入的研究，完全可以使用手动安装源码包的方式进行安装和配置。当然，你看到这篇文章的时候应该已经知道了Nginx的优秀之处了，后续文章会继续剖析Nginx的经典配置和Nginx与Apahce的异同。

　　最后在执行composer时候遇到问题，报错找不到mcrypt,一顿Google，终于找到解决办法，也粘贴如下

Try this:
 
sudo updatedb
locate mcrypt.ini
Should show it located at /etc/php5/mods-available
 
locate mcrypt.so
Edit mcrypt.ini and change extension to match the path to mcrypt.so, example:
 
extension=/usr/lib/php5/20121212/mcrypt.so
Now this:
 
php5enmod mcrypt - (optional since its already enabled during phpmyadmin setup)
Verify that new files exists here (they should be auto created from the issue above)
 
ls -al /etc/php5/cli/conf.d/20-mcrypt.ini
ls -al /etc/php5/apache2/conf.d/20-mcrypt.ini
Otherwise do the following
 
Create symbol links now
 
ln -s /etc/php5/mods-available/mcrypt.ini /etc/php5/cli/conf.d/20-mcrypt.ini
ln -s /etc/php5/mods-available/mcrypt.ini /etc/php5/apache2/conf.d/20-mcrypt.ini
Restart Apacahe
 
service apache2 restart

终于解决！
