LNMP

一、安装MySQL

参照本博配置LAMP文章 http://www.cnblogs.com/frankielf0921/articles/5371611.html

二、安装php

针对Nginx的php安装和针对apache的php安装是有区别的，

因为Nginx中的php是以fastcgi的方式结合nginx的，

可以理解为nginx代理了php的fastcgi，

而apache是把php作为自己的模块来调用的。

[rot@localhost ~]# cd /usr/local/src
[root@localhost src]# wget http://am1.php.net/distributions/php-5.3.27.tar.gz
[root@localhost src]# tar zxf php-5.3.27.tar.gz

[root@localhost src]# cd php-5.3.27
[root@localhost php-5.3.27]# ./configure 
--prefix=/usr/local/php 
--with-config-file-path=/usr/local/php/etc 
--enable-fpm 
--with-fpm-user=php-fpm 
--with-fpm-group=php-fpm 
--with-mysql=/usr/local/mysql

--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
[root@localhost  php-5.3.27]# make
[root@localhost  php-5.3.27]# make install
[root@localhost  php-5.3.27]# cp php.ini-production /usr/local/php/etc/php.ini  //拷贝配置文件

//此配置文件全为注释，可以留着查看 
//也可将其清空后再添加新内容
[root@localhost  php-5.3.27]# > /usr/local/php/etc/php-fpm.conf  
[root@localhost  php-5.3.27]# vim /usr/local/php/etc/php-fpm.conf
//写入以下内容
[global]
// pid设置，默认在安装目录中的var/run/php-fpm.pid，建议开启
pid = /usr/local/php/var/run/php-fpm.pid
// 错误日志，默认在安装目录中的var/log/php-fpm.log
error_log = /usr/local/php/var/log/php-fpm.log

[www]
// fpm监听端口，即nginx中php处理的地址，一般默认值即可。可用格式为: ‘ip:port’, ‘port’, ‘/path/to/unix/socket’. 每个进程池都需要设置.
listen = /tmp/php-fcgi.sock

// 启动进程的帐户和组
user = php-fpm
group = php-fpm

// 对于专用服务器，pm可以设置为static。
pm = dynamic
// 子进程最大数
pm.max_children = 50
// 启动时的进程数
pm.start_servers = 20
// 保证空闲进程数最小值，如果空闲进程小于此值，则创建新的子进程
pm.min_spare_servers = 5
// 保证空闲进程数最大值，如果空闲进程大于此值，此进行清理
pm.max_spare_servers = 35
// 设置每个子进程重生之前服务的请求数. 对于可能存在内存泄漏的第三方模块来说是非常有用的. 如果设置为 ’0′ 则一直接受请求. 等同于 PHP_FCGI_MAX_REQUESTS 环境变量. 默认值: 0.
pm.max_requests = 500
// 设置文件打开描述符的rlimit限制. 默认值: 系统定义值默认可打开句柄是1024，可使用 ulimit -n查看，ulimit -n 2048修改。
rlimit_files = 1024
[root@localhost  php-5.3.27]# /usr/local/php/sbin/php-fpm -t  //检测配置文件是否有错误
//出现诸如 “test is successful” 字样，说明配置没有问题。
[root@localhost  php-5.3.27]# cp /usr/local/src/php-5.3.27/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm //拷贝启动脚本
[root@localhost  php-5.3.27]# chmod 755 /etc/init.d/php-fpm  //修改权限
[root@localhost  php-5.3.27]# groupadd php-fpm
[root@localhost  php-5.3.27]# useradd -g php-fpm -s /sbin/nologin php-fpm   //账号用来运行php-fpm服务
[root@localhost  php-5.3.27]# service php-fpm start  //启动php-fpm
[root@localhost  php-5.3.27]# chkconfig php-fpm on
[root@localhost  php-5.3.27]# ps aux |grep php-fpm

　　

安装php会遇到的错误：--其他错误可查看LAMP配置文章

// 编译时遇到的错误 

1.  /usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [sapi/fpm/php-fpm] 

--> yum install -y libtool-ltdl-devel

2. error: Please reinstall the libcurl distribution -
    easy.h should be in <curl-dir>/include/curl/

--> yum install -y libcurl-devel


// 修改配置文件后，检测是否正确时的错误

三、安装nginx   -- 如果Apache正在运行，把Apache停掉。  { 有时两者会进行干扰 }

[root@localhost ~]# cd /usr/local/src
[root@localhost src]# wget http://nginx.org/download/nginx-1.4.4.tar.gz

[root@localhost nginx-1.4.4]# service nginx start
[root@localhost nginx-1.4.4]# ps aux|grep nginx

安装nginx会遇到的错误：

//编译安装时遇到的错误

1.  ./configure:
 error: the HTTP rewrite module requires the PCRE library.

--> yum -y install pcre-devel

如果此方法没办法解决，则需要去网上下载pcre的gz包

然后在nginx编译的时候加上

--with-pcre=../pcre-7.8.tar.gz(包名)

2.   /configure: error: the HTTP cache module requires md5 functions

from OpenSSL library.   You can either disable the module by using

--without-http-cache option, or install the OpenSSL library into the system,

or build the OpenSSL library statically from the source with nginx by using

--with-http_ssl_module --with-openssl=<path> options.

--> yum -y install openssl openssl-devel

四、测试是否解析php文件---虽说nginx和php都启动了，但要想两者结合，必须配置

[root@localhost nginx]# vim /usr/local/nginx/html/2.php
//加入以下内容
<?php
    echo "php works";
?>
[root@localhost nginx]# curl localhost/2.php
php works[root@localhost nginx]#
