centos 7 源码编译安装php5.6.37步骤及连接nginx简述

获取并解压 PHP 源代码

wget http://cn2.php.net/distributions/php-5.6.37.tar.gz
tar zxf php-5.6.37.tar.gz
cd php-5.6.37

为了防止编译出错安装依赖包

yum -y install gcc gcc-c++ autoconf libjpeg-turbo-static libjpeg-turbo-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel pcre pcre-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5-libs krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss-pam-ldapd openldap-clients openldap-servers bison lrzsz libmcrypt libmcrypt-devel mcrypt mhash ImageMagick ImageMagick-devel libmemcached libmemcached-devel

然后编译

./configure --prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--with-bz2 \
--with-curl \
--enable-ftp \
--enable-sockets \
--disable-ipv6 \
--with-gd \
--with-jpeg-dir=/usr/local \
--with-png-dir=/usr/local \
--with-freetype-dir=/usr/local \
--enable-gd-native-ttf \
--with-iconv-dir=/usr/local \
--enable-mbstring \
--enable-calendar \
--with-gettext \
--with-ldap \
--with-libxml-dir=/usr/local \
--with-zlib \
--with-pdo-mysql=mysqlnd \
--with-mysqli=mysqlnd \
--with-mysql=mysqlnd \
--enable-dom \
--enable-xml \
--enable-fpm \
--with-libdir=lib64 \
--enable-bcmath
--with-mysqli

•  

安装

make &&  make install

•  

修改配置文件

cp /root/php-5.6.37/php.ini-production /usr/local/php/etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
ln -s /usr/local/php/sbin/php-fpm /usr/local/sbin/php-fpm（创建php-fpm启动命令）
[[e-mail] etc]# cat php-fpm.conf
[global]
[www]
user = nginx(与nginx配置文件保持一致。我nginx中user是“nginx”)
group = nginx(同上)
listen = 127.0.0.1:9000
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

•  

然后启动 php-fpm 服务

php-fpm

•  

配置 Nginx 使其支持 PHP 应用 
修改默认的 location 块，使其支持 .php 文件：

location / {
    root   html;
    index  index.php index.html index.htm;
}

•  

下一步配置来保证对于 .php 文件的请求将被传送到后端的 PHP-FPM 模块， 取消默认的 PHP 配置块的注释，并修改为下面的内容：

location ~ \.php$ {
    root           html;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
} 

•  

重载nginx

\usr\local\nginx\sbin\nginx -s reload

 

创建PHP测试文件
打开浏览器，访问 相应IP地址，将会显示 phpinfo() 

注： 
nginx+php运行原理 
nginx本身不能处理PHP，它只是个web服务器，当接收到请求后，如果是php请求，则发给php解释器处理，并把结果返回给客户端。 
nginx一般是把请求发fastcgi（php-fpm就是其中的一种）管理进程处理，fascgi管理进程选择cgi子进程处理结果并返回被nginx 
同样php-fpm程序也如同nginx一样，需要监听端口，并且有master和worker进程。worker进程直接管理每一个php进程
