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.

PHP installation configuration

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

Add epel source

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Installation dependencies

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 \

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.

About php configuration

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. See /usr/share/nginx/README.dynamic.
# 用来加载其他动态模块的配置
include /usr/share/nginx/modules/*.conf;

# 工作模式和连接数上限
events {
    # 每个worker_processes的最大并发链接数
    # 并发总数：worker_processes*worker_connections
    worker_connections 1024;
}

# 与提供http服务相关的一些配置参数类似的还有mail
http {
    # 设置日志的格式
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    # access_log记录访问的用户、页面、浏览器、ip和其他的访问信息
    access_log  /var/log/nginx/access.log  main;

    # 这部分下面会单独解释
    # 设置nginx是否使用sendfile函数输出文件
    sendfile            on;
    # 数据包最大时发包(使用Nagle算法)
    tcp_nopush          on;
    # 立刻发送数据包(禁用Nagle算法)
    tcp_nodelay         on;
    # 链接超时时间
    keepalive_timeout   65;
    # 这个我也不清楚...
    types_hash_max_size 2048;

    # 引入文件扩展名与文件类型映射表
    include             /etc/nginx/mime.types;
    # 默认文件类型
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    # http服务上支持若干虚拟主机。
    # 每个虚拟主机一个对应的server配置项
    # 配置项里面包含该虚拟主机相关的配置。
    server {
        # 端口
        listen       80 default_server;
        listen       [::]:80 default_server;
        # 访问的域名
        server_name  _;
        # 默认网站根目录（www目录）
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.

        include /etc/nginx/default.d/*.conf;

        # 默认请求
        location / {
        }

        # 错误页(404)
        error_page 404 /404.html;
            location = /40x.html {
        }

        # 错误页(50X)
        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
}

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.

Only three changes are needed

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;
        }
    }

Restart the nginx server

nginx -s reload

At this time, nginx and php have been jointly configured, but we do not know the actual configuration effect How about, at this time we can write a small test script to verify it.

As mentioned before, /usr/share/nginx/html is the root directory of Nginx website. We can create a php test script in this directory.

# phpinfo.php is the name of the file I want to create

vi /usr/share/nginx/html/phpinfo.php

After opening the editor, enter

e2fef49b76a02e58cb8a935d1457623a

After saving and exiting, enter http in the browser: //192.168.0.222/phpinfo.php, my IP here is 192.168.0.222, you can change it to your own. As shown in the figure, an interface similar to the following appears:

Nginx and php have been configured.

4. Reasons for errors in the installation process

When I installed according to the process, an error occurred: mcrypt.h not found. Please reinstall libmcrypt

It is because php-mcrypt libmcrypt The libmcrypt-devel packages are not installed. The errors that occur are usually caused by missing libraries or packages. Just install them.

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!
