连接php/mysql

1 安装php5.6

首先确保mysql已安装

./configure --prefix=/app/php-5.6.36 --with-mysql=mysqlnd --enable-mysqlnd --with-gd --enable-gd-native-ttf --enable-gd-jis-conv --enable-fpm

　　

碰到一些依赖问题

yum install *libxml2* -y
yum install libjpeg-devel libpng-devel freetype-devel -y

　　

cp php.ini-development /app/php/lib/php.ini
#将下载的php安装包下的ini文件cp到安装目录/lib下。ini是php的初始化文件
cd etc
cp php-fpm.conf.default php-fpm.conf
#默认没有ftp conf，需要把default cp一个

　　

[root@webmaster php-5.6.36]# ps aux| grep php-fpm
root      65031  0.0  0.3 150760  3072 ?        Ss   12:07   0:00 php-fpm: master process (/app/php-5.6.36/etc/php-fpm.conf)
nobody    65032  0.0  0.2 152844  2992 ?        S    12:07   0:00 php-fpm: pool www
nobody    65033  0.0  0.4 152844  4248 ?        S    12:07   0:00 php-fpm: pool www

[root@webmaster php-5.6.36]# netstat -lnp| grep 9000
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      65031/php-fpm: mast 

　　

2 nginx对php的转发配置

nginx本身只处理静态网页，对于php网页，则专门做一个location映射，转发到php-fpm进程（默认监听在127.0.0.1 9000），然后php-fpm到对应的document_root找到fastcgi_script_name文件，然后返回给client。

location ~ .php$ {
    root           /data/jab.com/;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

　　

3 fastcgi

nginx和php通信的接口，包含很多参数，在2中的location配置中，必须加入include  fastcgi_params;参数，才能和php正常通信解析。nginx/conf下有fastcgi.conf文件。

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REQUEST_SCHEME     $scheme;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;
