Nginx环境下Php安装

其实很简单的事,我每次安装貌似都会走弯路,所以还是记下来吧

?

CentOS 5.5 Nginx 1.0.5Php 5.5.8

?

1.先安装Nginx

#tar -zxvf nginx-1.0.5.tar.gz#cd nginx-1.0.5#./configure#make#make install

?

2.安装php,采用fastcgi的安装方式,顺道查了下fastcgi的优势和劣势,供参考(摘抄自网络)

【注:我已经安装好了Mysql,因为没有太多特别的地方,所以就不做说明】

优势

  1. PHP脚本运行速度更快(3到30倍)。PHP解释程序被载入内存而不用每次需要时从存储器读取,极大的提升了依靠脚本运行的站点的性能。
  2. 需要使用更少的系统资源。由于服务器不用每次需要时都载入PHP解释程序,你可以将站点的传输速度提升很高而不必增加cpu负担。
  3. 不需要对现有的代码作任何改变。现有的一切都适用于PHP的FastCGI

潜在问题

  1. 对所有的子目录(/home/USERNAME/public_html/php.ini)你只有一个可用的php.ini文件。 这是优化网站代码所必需的。如果你需要多个php.ini文件以适应不同的脚本需要,你可以在任何子目录禁用PHP的快速CGI,而其余的地方则继续有 效。如果你需要这样做请联系support。
  2. 你对PHP环境做的任何升级(如php.ini文件的改变)都有几分钟的延迟。这是因为为了更快的速度 你的php.ini文件已经被载入内存,而不是每次需要时再从存储器重新读取。

我在安装的时候并没有去考虑php.ini的问题,只要考虑好php-fpm.conf就可以了

php的安装的确是稍微不太一样,简单的说,就是作为一个单独的服务启动了

#tar -zxvf php-5.3.8.tar.gz#cd php-5.3.8// 编译的时候一定要加入参数--enable-fpm#./configure --prefix=/usr/local/php --with-gd --enable-gd-native-ttf --enable-gd-jis-conv --with-mysql=/usr/local/mysql/  --with-pdo-mysql=/usr/local/mysql --enable-soap --enable-sockets --enable-zip --enable-xml --with-curl --enable-mbregex --enable-sysvsem --enable-mbstring --with-mcrypt --enable-fpm#make#make install

?

3.配置php和nginx

1.使用php-fpm启动php

#cd /usr/local/php/etc/#cp php-fpm.conf.default php-fpm.conf#vi php-fpm.conf// 找到如下几行,确保如下几行前没有";"pid = run/php-fpm.piderror_log = log/php-fpm.loglisten = 127.0.0.1:9000pm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500

?php5.5.8版本提供了php-fpm的管理工具,可以很方便的start,stop,restart

// 只是我个人习惯把php相关命令丢在这#cd /usr/local/php/sbin/// 在安装文件中复制该文件#cp /downloads/php-5.3.8/sapi/fpm/init.d.php-fpm ./#chmod 755 init.d.php-fpm// start | stop | restart#./init.d.php-fpm start

?

2.nginx的配置?

#vi /usr/local/nginx/conf/nginx.conf// 去掉之前的"#"// SCRIPT_FILENAME如果填错,则显示空白页面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;        }#vi /usr/local/nginx/conf/fastcgi_params// 注释掉该行,暂时还不知道为啥#fastcgi_param  REDIRECT_STATUS    200;

?启动nginx

#cd /usr/local/nginx/sbin/// 测试配置文件是否正确#./nginx -t// 启动#./nginx // 重新载入#./nginx -s reload// 重启#./nginx -s reopen
?
