How to compile and install php5.6.31?
CentOS 7 Compile and install PHP5.6.31:
There are already nginx and mysql on the server, so I decided to use PHP Nginx mysql For this combination, I read a lot of information on the Internet. Since I don’t know much about Linux and PHP, and I don’t know how PHP is related to nginx and mysql, I encountered various reasons (either PHP was installed incorrectly, or the package was not installed), It took a lot of time, but after the deployment, I found that these three are installed separately (well~~ can they be installed together), you only need to configure PHP after installation, and configure nginx (associated with PHP). Ran. As for mysql, as long as it is turned on and the connection database in the php project is configured, you can connect directly. So this article mainly focuses on the installation of php.
Regarding the installation of nginx and mysql, some development libraries for Linux need to be installed before starting the installation. I will not repeat them here. They are all in the reference link.
nginx itself cannot handle PHP. It is just a WEB server. When a request is received, if it is a PHP request, it is sent to the PHP interpreter for processing and the result is returned. to the client.
nginx generally sends the request to the fastcgi management process for processing. The fastcgi management process selects the cgi sub-process processing result and returns it to nginx.
What is PHP-FPM? PHP-FPM is a FASTCGI manager for PHP. It is only used for PHP. The new version has integrated php-fpm. php-fpm provides better php process management, can effectively control memory and processes, and can smoothly reload php configuration. . When configuring, you can enable php-fpm with the -enable-fpm parameter. Other parameters can be found here. As for what fastcgi is and its relationship with php-fpm, please refer to the link https://segmentfault.com/q/1010000000256516
Preparation before installation
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum install gcc bison bison-devel zlib-devel libmcrypt-devel mcrypt mhash-devel openssl-devel libxml2-devel libcurl-devel bzip2-devel readline-devel libedit-devel sqlite-develyum -y install gcc gcc-c++ glibcyum -y install libmcrypt-devel mhash-devel libxslt-devel \ libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel \ zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel \ ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel \ krb5 krb5-devel libidn libidn-devel openssl openssl-devel
Downloadphp-5.6.31
1) Unzip the installation package to /usr/local/src
cd /usr/local/srctar -zvxf php-5.6.31.tar.gz
2) Enter the installation directory, Installation
cd php-5.6.31./configure --prefix=/usr/local/php --enable-fpm --with-mcrypt \--enable-mbstring --enable-pdo --with-curl --disable-debug --disable-rpath \--enable-inline-optimization --with-bz2 --with-zlib --enable-sockets \--enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex \--with-mhash --enable-zip --with-pcre-regex --with-mysql --with-mysqli \--with-gd --with-jpeg-dir --with-freetype-dir --enable-calendarmake && make install
CentOS 中下载php: wget http://php.net/get/php-5.6.30.tar.gz/from/this/mirror
The above completes the installation of php-fpm. The installation process will take some time.
1. Provide configuration files for php
cp php.ini-production /usr/local/php/etc/php.ini
Note: php.ini-production is still in /usr/local/src/php-5.6. 31 directory
2. Provide configuration file for php-fpm
cd /usr/local/phpcp etc/php-fpm.conf.default etc/php-fpm.conf vim etc/php-fpm.conf
Modify php-fpm.conf
user = www group = www
If the www user does not exist, add the www user first ( The default running user is nobody)
groupadd www useradd -g www www
If this step is not configured, the browser will report an error when opening the php file
"The page you are looking for is temporarily unavailable . Please try again later”
Modify
pm.max_children = 150 pm.start_servers = 8 pm.min_spare_servers = 5 pm.max_spare_servers = 10 pid = /usr/local/php/var/run/php-fpm.pid
3. Start php-fpm
Execute
/usr/local/php/sbin/php-fpm
Use the following command to verify ( If there are several php-fpm processes in the output of this command, it means the startup is successful):
ps aux | grep php-fpm
The result is as shown below:
3, nginx and php -fpm integration
Edit nginx configuration file
vim /usr/local/nginx/conf/nginx.conf
The initial content is as follows:
# nginx运行的用户名 user nginx; # nginx启动进程,通常设置成和cpu的数量相等,这里为自动 worker_processes auto; # errorlog文件位置 error_log /var/log/nginx/error.log; # pid文件地址,记录了nginx的pid,方便进程管理 pid /run/nginx.pid; # Load dynamic modules.

We only need to change the configurationserver
## The # part is fine. Enter vim editing mode, or use FlashFXP to share the configuration file to the desktop to make changes.
server { listen 80 default_server; listen [::]:80 default_server; # 这里改动了,也可以写你的域名,我用的是IP地址 server_name 192.168.0.222; root /usr/share/nginx/html; # Load configuration files for the default server block. include /etc/nginx/default.d/*.conf; location / { # 这里改动了 定义首页索引文件的名称 index index.php index.html index.htm; } error_page 404 /404.html; location = /40x.html { } error_page 500 502 503 504 /50x.html; location = /50x.html { } # 这里新加的 # PHP 脚本请求全部转发到 FastCGI处理. 使用FastCGI协议默认配置. # Fastcgi服务器和程序(PHP,Python)沟通的协议. location ~ \.php$ { # 设置监听端口 fastcgi_pass 127.0.0.1:9000; # 设置脚本文件请求的路径 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; # 引入fastcgi的配置文件 include fastcgi_params; } }
nginx -s reload
As mentioned before, /usr/share/nginx/html is the root directory of Nginx website. We can create a php test script in this directory.
vi /usr/share/nginx/html/phpinfo.php
<?php phpinfo();// 测试信息?>
At this point, PHP has been configured. I wish you a smooth installation. By the way, I wish you all a Happy New Year in advance!
