How to Enable Multiple PHP-FPM Instances with Nginx / Apache
|
||||
================================================================================
|
||||
|
||||
PHP-FPM is also known as PHP FastCGI Process Manager. It is an advancement of PHP FastCGI implementation with more useful features for handling heavy-loaded servers and websites. Some of those features are listed below:
|
||||
|
||||
### New Features ###
|
||||
|
||||
- Advanced process managament capability with graceful start/stop options.
|
||||
- Ability to run the processes with different userids/groupids listening on different ports and using different PHP configurations.
|
||||
- Error logging.
|
||||
- Acceleration upload support
|
||||
- Special function to finish request and flush all data while doing some time consuming tasks
|
||||
- Both Dynamic and Static Child process Spawning
|
||||
- IP Address restriction
|
||||
|
||||
In this article, I'm going to discuss about installing PHP-FPM along with Nginx and Apache on a CentOS 7 server running cPanel 11.52 with EA3(EasyApache) and how to manage those installed multiple PHP-FPM instances via CPanel.
|
||||
|
||||
Before going to the installation procedures, let us take a look on the pre-requisites.
|
||||
|
||||
### Pre-requisites ###
|
||||
|
||||
1. Enable Mod_proxy_fcgi module
|
||||
2. Enable MPM_Event
|
||||
|
||||
Since, we are installing PHP-FPM on a EA3 server, we need to run EasyApache to compile Apache to enable these modules.
|
||||
|
||||
You can refer my previous document on how to install Nginx as reverse proxy on a Apache server to confirm with the Nginx installation.
|
||||
|
||||
I'll brief those installation steps once again here. You can refer to my previous documentation **(How to Set Nginx as Reverse Proxy on CentOS 7 /CPanel Server)** for details.
|
||||
|
||||
Step 1: Install the Epel repo
|
||||
Step 2: Install nDeploy RPM repo which is the most **IMPORTANT** step in this installation.
|
||||
Step 3: Install nDeploy and Nginx plugin using yum from the nDeploy repo.
|
||||
Step 4: Enable/Configure Nginx as reverse proxy
|
||||
|
||||
Once this is done, install the PHP-FPM packages for all PHP versions available in the server. EA3 uses remi repository for installing these packages. You can run this nDeploy script to download all packages.
|
||||
|
||||
root@server1 [~]# /opt/nDeploy/scripts/easy_php_setup.sh
|
||||
Loaded plugins: fastestmirror, tsflags, universal-hooks
|
||||
EA4 | 2.9 kB 00:00:00
|
||||
base | 3.6 kB 00:00:00
|
||||
epel/x86_64/metalink | 9.7 kB 00:00:00
|
||||
epel | 4.3 kB 00:00:00
|
||||
extras | 3.4 kB 00:00:00
|
||||
updates | 3.4 kB 00:00:00
|
||||
(1/2): epel/x86_64/updateinfo | 460 kB 00:00:00
|
||||
(2/2): epel/x86_64/primary_db
|
||||
|
||||
Running this script will install all these FPM packages for PHP 54, PHP 55, PHP 56 and PHP 70.
|
||||
|
||||
Installed Packages
|
||||
php54-php-fpm.x86_64 5.4.45-3.el7.remi @remi
|
||||
php55-php-fpm.x86_64 5.5.31-1.el7.remi @remi
|
||||
php56-php-fpm.x86_64 5.6.17-1.el7.remi @remi
|
||||
php70-php-fpm.x86_64 7.0.2-1.el7.remi @remi
|
||||
|
||||
After this installation, you need to enable PHP-FPM SAPI for Apache. You can run this script to enable PHP-FPM instances.
|
||||
|
||||
root@server1 [~]# /opt/nDeploy/scripts/apache_php-fpm_setup.sh enable
|
||||
mod_proxy_fcgi.c
|
||||
Please choose one default PHP version from the list below
|
||||
PHP70
|
||||
PHP56
|
||||
PHP54
|
||||
PHP55
|
||||
Provide the exact desired version string here and press ENTER: PHP54
|
||||
ConfGen:: lxblogger
|
||||
ConfGen:: blogr
|
||||
ConfGen:: saheetha
|
||||
ConfGen:: satest
|
||||
which: no cagefsctl in (/usr/local/jdk/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/bin:/usr/X11R6/bin:/root/bin)
|
||||
info [rebuildhttpdconf] Missing owner for domain server1.centos7-test.com, force lookup to root
|
||||
Built /usr/local/apache/conf/httpd.conf OK
|
||||
Waiting for “httpd” to restart gracefully …waiting for “httpd” to initialize ……
|
||||
…finished.
|
||||
|
||||
It will ask the required PHP version which you prefer to run as default on the server. You can enter those details and proceed to configure and generate the virtual host files for the existing domains.
|
||||
|
||||
I've chosen PHP 54 as the default PHP-FPM version on my server.
|
||||
|
||||
|
||||
|
||||
Even though, the server is configured with PHP-FPM 54, we can modify the PHP-FPM instances for the individual domains via cPanel.
|
||||
|
||||
I'll explain you on how to modify the PHP-FPM instances for individual domains via cPanel using some screenshots.
|
||||
|
||||
The installation of Nginx plugin will provide you with an icon of Nginx Webstack in your domain's cPanel. You can click on that icon to configure your Web server. I've logged into one of my domain's cPanel to configure it's Web server.
|
||||
|
||||
Please check these snapshots.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
Now you can configure the web-server for the selected main domain as required(I've selected the main domain saheetha.com here). I've gone ahead with automatic configuration options since, I don't have any manual settings to add.
|
||||
|
||||
|
||||
|
||||
Once Nginx is configured, you can select the PHP-FPM instance for your domain here.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
As you can see in these snapshots, my default PHP-FPM on the server is **PHP 54** and I'm changing the PHP-FPM instance for my domain alone to **PHP 55**. Once you've modified the PHP-FPM for your domain, you can confirm it by accessing the **phpinfo** page.
|
||||
|
||||
Thank you for referring to this article. I believe this article is really informative and useful for you. I would recommend your valuable comments on this :).

启用Nginx/Apache的PHP-FPM多实例
|
||||
================================================================================
|
||||
|
||||
PHP-FPM作为FastCGI进程管理器而广为熟知，它是PHP FastCGI实现的改进，带有更为有用的功能，用于处理高负载的服务器和网站。下面列出其中一些功能：
|
||||
### 新功能 ###
|
||||
|
||||
- 拥有具有优雅启动/停止选项的高级进程管理能力。
|
||||
- 可以以监听不同端口以及使用不同PHP配置的不同用户身份/组身份来运行进程。
|
||||
- 错误日志记录。
|
||||
- 支持上传加速。
|
||||
- 用于在处理一些耗时任务时结束请求和清空所有数据的特别功能。
|
||||
- 同时支持动态和静态子进程重生。
|
||||
- 支持IP地址限制。
|
||||
|
||||
在本文中，我将要讨论的是，在运行EA3下CPanel 11.52的CentOS 7服务器上与Nginx和Apache一起安装PHP-FPM，以及如何来通过CPanel管理这些安装好的多个PHP-FPM实例。
|
||||
Before going to the installation procedures, let us take a look on the pre-requisites.
|
||||
|
||||
### 先决条件 ###
|
||||
|
||||
1. 启用 Mod_proxy_fcgi模块
|
||||
2. 启用 MPM_Event
|
||||
|
||||
由于我们要将PHP-FPM安装到一台EA3服务器，我们需要运行EasyApache来编译Apache以启用这些模块。
|
||||
|
||||
你们可以参考我以前写的，关于如何在Apache服务器上安装Nginx作为反向代理的文档来确认Nginx的安装。
|
||||
|
||||
这里，我将再次简述那些安装步骤。具体细节，你可以参考我之前写的**（如何在CentOS 7/CPanel服务器上配置Nginx反向代理）**一文。
|
||||
|
||||
步骤 1：安装Epel仓库
|
||||
步骤 2：安装nDeploy RPM仓库，这是此次安装中最为**重要**的步骤。
|
||||
步骤 3：使用yum从nDeploy仓库安装nDeploy和Nginx插件。
|
||||
步骤 4：启用/配置Nginx为反向代理。
|
||||
|
||||
完成这些步骤后，下面为服务器中所有可用PHP版本安装PHP-FPM包，EA3使用remi仓库来安装这些包。你可以运行这个nDeploy脚本来下载所有的包。
|
||||
|
||||
root@server1 [~]# /opt/nDeploy/scripts/easy_php_setup.sh
|
||||
Loaded plugins: fastestmirror, tsflags, universal-hooks
|
||||
EA4 | 2.9 kB 00:00:00
|
||||
base | 3.6 kB 00:00:00
|
||||
epel/x86_64/metalink | 9.7 kB 00:00:00
|
||||
epel | 4.3 kB 00:00:00
|
||||
extras | 3.4 kB 00:00:00
|
||||
updates | 3.4 kB 00:00:00
|
||||
(1/2): epel/x86_64/updateinfo | 460 kB 00:00:00
|
||||
(2/2): epel/x86_64/primary_db
|
||||
|
||||
运行该脚本将为PHP 54，PHP 55，PHP 56和PHP 70安装所有这些FPM包。
|
||||
|
||||
Installed Packages
|
||||
php54-php-fpm.x86_64 5.4.45-3.el7.remi @remi
|
||||
php55-php-fpm.x86_64 5.5.31-1.el7.remi @remi
|
||||
php56-php-fpm.x86_64 5.6.17-1.el7.remi @remi
|
||||
php70-php-fpm.x86_64 7.0.2-1.el7.remi @remi
|
||||
|
||||
在以上安装完成后，你需要为Apache启用PHP-FPM SAPI。你可以运行下面这个脚本来启用PHP-FPM实例。
|
||||
|
||||
root@server1 [~]# /opt/nDeploy/scripts/apache_php-fpm_setup.sh enable
|
||||
mod_proxy_fcgi.c
|
||||
Please choose one default PHP version from the list below
|
||||
PHP70
|
||||
PHP56
|
||||
PHP54
|
||||
PHP55
|
||||
Provide the exact desired version string here and press ENTER: PHP54
|
||||
ConfGen:: lxblogger
|
||||
ConfGen:: blogr
|
||||
ConfGen:: saheetha
|
||||
ConfGen:: satest
|
||||
which: no cagefsctl in (/usr/local/jdk/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/bin:/usr/X11R6/bin:/root/bin)
|
||||
info [rebuildhttpdconf] Missing owner for domain server1.centos7-test.com, force lookup to root
|
||||
Built /usr/local/apache/conf/httpd.conf OK
|
||||
Waiting for “httpd” to restart gracefully …waiting for “httpd” to initialize ……
|
||||
…finished.
|
||||
|
||||
它会问你需要运行哪个PHP版本作为服务器默认版本，你可以输入那些细节内容，然后继续配置并为现存的域生成虚拟主机文件。
|
||||
|
||||
我选择了PHP 54作为我服务器上的默认PHP-FPM版本。
|
||||
|
||||
|
||||
|
||||
虽然服务器配置了PHP-FPM 54，但是我们可以通过CPanel为各个独立的域修改PHP-FPM实例。
|
||||
|
||||
下面我将通过一些截图来为你们说明一下，怎样通过CPanel为各个独立域修改PHP-FPM实例。
|
||||
|
||||
Nginx插件的安装将为你的域的CPanel提供一个Nginx Webstack图标，你可以点击该图标来配置你的Web服务器。我已经登陆进了我其中的一个CPanel来配置相应的Web服务器。
|
||||
|
||||
请看这些截图。
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
现在，你可以根据需要为选中的主域配置web服务器（这里，我已经选择了主域saheetha.com）。我已经继续通过自动化配置选项来进行了，因为我不需要添加任何手动设置。
|
||||
|
||||
|
||||
|
||||
当Nginx配置完后，你可以在这里为你的域选择PHP-FPM实例。
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
就像你在截图中所看到的，我服务器上的默认PHP-FPM是**PHP 54**，而我正要将我的域的PHP-FPM实例单独修改成**PHP 55**。当你为你的域修改PHP-FPM后，你可以通过访问**phpinfo**页面来确认。
|
||||
|
||||
谢谢你们参考本文，我相信这篇文章会给你提供不少信息和帮助。我会为你们推荐关于这个内容的有价值的评论 :)。
