LNMP环境搭建

LNMP环境搭建（基于Centos6.7 32位Linux操作系统）

一、linux环境安装

二、MySQL安装，参考LAMP安装过程：http://daixuan.blog.51cto.com/5426657/1717409

三、PHP编译安装

注意：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

1、下载PHP源码包，解压

[root@daixuan ~]# cd /usr/local/src

[root@daixuan src]# wget http://cn2.php.net/distributions/php-5.4.37.tar.bz2

[root@daixuan src]# tar jxvf php-5.4.37.tar.bz2

[root@daixuan src]# ls

php-5.4.37

2、创建相关账户

[root@daixuan src]# useradd -s /sbin/nologin php-fpm

3、配置编译选项

注意：由于之前在该虚拟机上安装了LAMP，安装过php，这里需要先删除

[root@daixuan php-5.4.37]# rm -rf /usr/local/php/

[root@daixuan src]# cd php-5.4.37

[root@daixuan php-5.4.37]# ./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-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

[root@daixuan php-5.4.37]# echo $?   //结果为0说明没有报错

0

这里如果有报错，可能是某些库没有安装，例如：安装libcurl库：yum install -y libcurl-delevel

4、编译PHP

[root@daixuan php-5.4.37]# make

[root@daixuan php-5.4.37]# echo $?

0

注：如果这里遇到这样的错误，解决方法是：yum install -y libtool-ltdl-devel

/usr/bin/ld: cannot find -lltdl

collect2: ld returned 1 exit status

make: *** [sapi/fpm/php-fpm]

5、安装PHP

[root@daixuan php-5.4.37]# make install

6、修改配置文件

[root@daixuan php-5.4.37]# cp php.ini-production /usr/local/php/etc/php.ini

[root@daixuan php-5.4.37]# cd /usr/local/php/etc/   

[root@daixuan etc]# mv php-fpm.conf.default php-fpm.conf

[root@daixuan etc]# ls

pear.conf  php-fpm.conf  php.ini

保存配置文件后，检验配置是否正确的方法为:

[root@daixuan etc]# /usr/local/php/sbin/php-fpm -t

[05-Jan-2016 20:24:32] NOTICE: configuration file /usr/local/php/etc/php-fpm.conf test is successful

test is successful字样，说明配置没有问题

7、拷贝启动脚本

[root@daixuan src]# cd /usr/local/src/php-5.4.37

首先是拷贝一个php的启动脚本到/etc/init.d/下：

[root@daixuan php-5.4.37]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

[root@daixuan php-5.4.37]# chmod 755 /etc/init.d/php-fpm

添加php-fpm到服务列表中，让它开机启动

[root@daixuan php-5.4.37]# chkconfig --add php-fpm

[root@daixuan php-5.4.37]# chkconfig php-fpm on

[root@daixuan php-5.4.37]# service php-fpm start

Starting php-fpm  done

查看php-fpm的进程：

[root@daixuan php-5.4.37]# netstat -lnp

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address  Foreign Address   State       PID/Program name

tcp   0    0   127.0.0.1:9000   0.0.0.0:*      LISTEN      19901/php-fpm

[root@daixuan php-5.4.37]# ps aux | grep php-fpm

root 19901 0.0 0.1 26084 2976 ? Ss 20:17 0:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)            

php-fpm  19902  0.0  0.1  26084  2644 ?  S  20:17   0:00 php-fpm: pool www     php-fpm  19903  0.0  0.1  26084  2644 ?   S    20:17   0:00 php-fpm: pool www   

root    19926  0.0  0.0   6048   780 pts/0   S+   20:20   0:00 grep php-fpm

二、Nginx编译安装

1、下载解压Nginx

[root@daixuan src]# cd /usr/local/src/

[root@daixuan src]# wget http://nginx.org/download/nginx-1.8.0.tar.gz  

[root@daixuan src]# tar zxvf nginx-1.8.0.tar.gz

[root@daixuan src]# ls

nginx-1.8.0

nginx-1.8.0.tar.gz

2、配置编译选项

[root@daixuan nginx-1.8.0]# cd nginx-1.8.0

[root@daixuan nginx-1.8.0]# ./configure \

--prefix=/usr/local/nginx \

--with-http_realip_module \

--with-http_sub_module \

--with-http_gzip_static_module \ 

--with-http_stub_status_module \ 

--with-pcre 

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

You can either disable the module by using --without-http_rewrite_module

option, or install the PCRE library into the system, or build the PCRE library

statically from the source with nginx by using --with-pcre=<path> option.

[root@daixuan nginx-1.8.0]# echo $?

1

发现有错误，解决方法，安装pcre库，重新配置编译选项

[root@daixuan nginx-1.8.0]# yum install -y pcre-devel

[root@daixuan nginx-1.8.0]# echo $?

0

3、编译Nginx

[root@daixuan nginx-1.8.0]#make

4、安装

[root@daixuan nginx-1.8.0]#make install

5、启动Nginx

[root@daixuan nginx-1.8.0]# cd /usr/local/nginx/

[root@daixuan nginx]# ls sbin/nginx

sbin/nginx

启动nginx，报错：

[root@daixuan nginx]# /usr/local/nginx/sbin/nginx

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] still could not bind()

[root@daixuan nginx]# netstat -lnp

tcp  0  0 ::ffff:127.0.0.1:8005  :::*    LISTEN      2183/java

tcp  0  0 :::8009            :::*   LISTEN      2183/java

tcp  0  0 :::80             :::*    LISTEN      2183/java

这里报错是因为80端口已经被tomcat占用，需要先关闭tomcat

[root@daixuan nginx]# service tomcat stop

重新启动nginx

[root@daixuan nginx]# /usr/local/nginx/sbin/nginx

[root@daixuan nginx]# ps aux | grep nginx

root30631 0.1 0.0 5028 644 ? Ss 21:160:00 nginx: master process /usr/local/nginx/sbin/nginx

nobody   30632  0.1  0.0   5232   980 ?  S    21:16   0:00 nginx: worker process

root     30636  0.0  0.0   6048   780 pts/0    S+   21:16   0:00 grep nginx

三、测试PHP解析

1、修改nginx配置文件，使其支持php

[root@daixuan nginx]# vim /usr/local/nginx/conf/nginx.conf

把这一段注释去掉,让其生效，/usr/local/nginx/html是PHP的文件目录

location ~ \.php$ {

        root           html;

        fastcgi_pass   127.0.0.1:9000;

        fastcgi_index  index.php;

        fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;

        include        fastcgi_params;

      }

[root@daixuan nginx]# /usr/local/nginx/sbin/nginx -s reload //重新加载nginx配置文件

[root@daixuan ~]# cd /usr/local/nginx/html

[root@daixuan html]# vim info.php

<?php

phpinfo();

?>
