MP和LNMP可以并存，但是端口（80）冲突，需要修改端口；
LNMP须重新安装PHP，编译参数不一样。LAMP中apache需要与PHP建立关联；

LNMP和LAMP可以实现数据迁移，因为本身的数据库没变化

1.安装mysql，参照LAMP的随笔

2.安装PHP（须重新安装）

tar zxf php-5.5.30.tar.gz

useradd -s /sbin/nologin php-fpm                      //添加php相关账户

cd php-5.3.27             
./configure \                                 //配置编译参数

--prefix=/usr/local/nginx_php \

--with-config-file-path=/usr/local/nginx_php/etc\

--enable-fpm \

--with-fpm-user=php-fpm \

--with-fpm-group=php-fpm \

--with-mysql=/usr/local/mysql \

--with-mysql-sock=/tmp/mysql.sock \

--with-libxml-dir \

--with-gd \

--with-jpeg-dir \

--with-png-dir \

--with-freetype-dir \

--with-iconv-dir \

--with-zlib-dir \

--with-mcrypt \

--enable-soap \

--enable-gd-native-ttf \

--enable-ftp \

--enable-mbstring \

--enable-exif \

--enable-zend-multibyte \

--disable-ipv6 \

--with-pear \

--with-curl \

--with-openssl
注: (报错解决方法)

yum list|grep libcurl

yum install libcurl-devel.x86_64

make                            
make install
cp php.ini-production /usr/local/nginx_php/etc/php.ini //配置文件
cp /usr/local/src/php-5.5.30/sapi/fpm/init.d.php-fpm etc/init.d/php-fpm      //拷贝启动文件
chmod 755 /etc/init.d/php-fpm                                                               //  更改权限                                                    
chkconfig  --add php-fpm                                                                        //添加开机启动php-fpm服务
chkconfig php-fpm on
chkconfig --list|grep php-fpm
cp sapi/fpm/php-fpm.conf /usr/local/nginx_php/etc/   //配置文件/etc/init.d/php-fpm  startps aux|grep php             
3.nginx的安装

cd ..

wget http://nginx.org/download/nginx-1.4.4.tar.gz

tar zxvf nginx-1.4.4.tar.gz

cd nginx-1.4.4

 ./configure --prefix=/usr/local/nginx--with-pcre                                 //配置编译参数

yum list|grep pcre                                                                        // error解决办法

yum install pcre-devel.x86_64

./configure --prefix=/usr/local/nginx--with-pcre                                   //继续配置参数

make

make install

vim /usr/local/nginx/conf/nginx.conf                                               //修改配置文件

                                //须修改 root后为：/data/123（为自己网站所在目录）；
                                //默认页面index中添加 :   index.php;


                        //白字部分需要去掉注释，并根据自己配置进行修改
                 

/usr/local/nginx/sbin/nginx –t                                  //查错

killall httpd                                                          //结束httpd服务，防止接口冲突

/usr/local/nginx/sbin/nginx                                     //启动nginx

/usr/local/nginx/sbin/nginx -s reopen                     //重启nginx

ps aux|grep nginx                                                //查看nginx进程

4.测试网站
浏览器中输入 127.0.0.1

LNMP环境的搭建
