LNMP环境搭建

2331

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

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
[iyunv@daixuan ~]# cd /usr/local/src
[iyunv@daixuan src]# wget http://cn2.php.net/distributions/php-5.4.37.tar.bz2
[iyunv@daixuan src]# tar jxvf php-5.4.37.tar.bz2
[iyunv@daixuan src]# ls
php-5.4.37

2、创建相关账户
[iyunv@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
[iyunv@daixuan php-5.4.37]# rm -rf /usr/local/php/
[iyunv@daixuan src]# cd php-5.4.37
[iyunv@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
[iyunv@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
[iyunv@daixuan php-5.4.37]# make

[iyunv@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
[iyunv@daixuan php-5.4.37]# make install

6、修改配置文件
[iyunv@daixuan php-5.4.37]# cp php.ini-production /usr/local/php/etc/php.ini

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

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

[iyunv@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:

[iyunv@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
[iyunv@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：
[iyunv@daixuan php-5.4.37]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[iyunv@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
[iyunv@daixuan php-5.4.37]# chkconfig --add php-fpm
[iyunv@daixuan php-5.4.37]# chkconfig php-fpm on
[iyunv@daixuan php-5.4.37]# service php-fpm start
Starting php-fpm  done
查看php-fpm的进程：
[iyunv@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
[iyunv@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
[iyunv@daixuan src]# cd /usr/local/src/
[iyunv@daixuan src]# wget http://nginx.org/download/nginx-1.8.0.tar.gz  
[iyunv@daixuan src]# tar zxvf nginx-1.8.0.tar.gz
[iyunv@daixuan src]# ls
nginx-1.8.0
nginx-1.8.0.tar.gz

2、配置编译选项
[iyunv@daixuan nginx-1.8.0]# cd nginx-1.8.0
[iyunv@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.
[iyunv@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
[iyunv@daixuan nginx-1.8.0]# yum install -y pcre-devel
[iyunv@daixuan nginx-1.8.0]# echo $?
0

3、编译Nginx
[iyunv@daixuan nginx-1.8.0]#make

4、安装
[iyunv@daixuan nginx-1.8.0]#make install

5、启动Nginx
[iyunv@daixuan nginx-1.8.0]# cd /usr/local/nginx/
[iyunv@daixuan nginx]# ls sbin/nginx
sbin/nginx
启动nginx，报错：
[iyunv@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()
[iyunv@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
[iyunv@daixuan nginx]# service tomcat stop
重新启动nginx
[iyunv@daixuan nginx]# /usr/local/nginx/sbin/nginx
[iyunv@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

[iyunv@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;
      }
[iyunv@daixuan nginx]# /usr/local/nginx/sbin/nginx -s reload //重新加载nginx配置文件
[iyunv@daixuan ~]# cd /usr/local/nginx/html
[iyunv@daixuan html]# vim info.php
<?php
phpinfo();
?>
