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！
