How to add extensions to yum php7.1?

Tutorial on how to deploy php7.1 under CentOS 7 and enable MySQL extension

Preface

Previously installed php7.1 on CentOS7 Sometimes I encountered the problem that the PHP source and PHP7.1 did not support the MySQL extension. I took the time to install it in the morning and finally solved these two problems. I hereby record the memo.

Simple installation (yum method)

Install software source

Add epel source

[root@opstrip.com opt]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*
[root@opstrip.com opt]# rpm -Uvh http://mirrors.rit.edu/fedora/epel//7/x86_64/e/epel-release-7-9.noarch.rpm

Add remi source

[root@opstrip.com opt]# rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Install and update Software

Install the yum-config-manager utility

[root@opstrip.com opt]# yum -y install yum-utils

Update the current software version of the system

[root@opstrip.com opt]# yum -y update

After the update is completed, you can install the required PHP version.

Install PHP

After the above preparations are completed, you can install the required PHP version.

For PHP5.4

[root@opstrip.com opt]# yum -y install php

Before installation, you can try yum search php54 to search for installable software packages.

For PHP7.0

[root@opstrip.com opt]# yum-config-manager --enable remi-php70
[root@opstrip.com opt]# yum -y install php php-opcache

Before installation, you can try yum search php70 to search for installable software packages.

For PHP7.1

[root@opstrip.com opt]# yum-config-manager --enable remi-php71
[root@opstrip.com opt]# yum -y install php php-opcache

Before installation, you can try yum search php71 to search for installable software packages.

After completion, you need to add common PHP extensions:

[root@opstrip.com opt]# yum -y install php-mysql php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-soap curl curl-devel

For Nginx

[root@opstrip.com opt]# yum -y install nginx nginx-mod-http-perl nginx-mod-stream nginx-filesystem nginx-mod-mail nginx-mod-http-image-filter nginx-all-modules nginx-mod-http-geoip nginx-mod-http-xslt-filter

It is still recommended to try yum search nginx to search for installable software packages before installation.

After the installation is complete, configure PHP and Nginx and start it to test the phpinfo page. It should be displayed normally at this time.

Source code compilation and installation

Preparation before installation

Download PHP installation package

[root@opstrip.com opt]# wget -O php-7.1.5.tar.gz http://cn2.php.net/distributions/php-7.1.5.tar.gz

Unzip

[root@opstrip.com opt]# tar xf php-7.1.5.tar.gz

Install dependency package

[root@opstrip.com php-7.1.5]# yum install -y libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel

For details, please refer to the official PHP installation instructions document: http://php.net/manual/zh/install.unix.nginx.php

Compile and install

[root@opstrip.com php-7.1.5]# make && make install

Configure environment variables:

Append export PATH=$PATH:/usr/local/php/bin at the end of /etc/profile, and then execute source / Check the php version after etc/profile takes effect:

[root@opstrip.com php-7.1.5]# php -v
PHP 7.1.5 (cli) (built: May 31 2017 16:12:38) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies

Configuration after installation

Configuration php-fpm

After the installation is completed, you can use sapi/fpm/php-fpm.server Let’s start php-fpm. However, for the convenience of future management, it is usually necessary to place the configuration files in the /etc directory and add php-fpm.server to the systemctl service. As follows:

[root@opstrip.com php-7.1.5]# mkdir -p /etc/php-fpm.d
[root@opstrip.com php-7.1.5]# cp php.ini-production /etc/php.ini
[root@opstrip.com php-7.1.5]# cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/
[root@opstrip.com php-7.1.5]# cp sapi/fpm/www.conf /etc/php-fpm.d/

Then change the /usr/lib/systemd/system/php-fpm.service file to execute the correct path, as follows:

[root@opstrip.com php-7.1.5]# vi /usr/lib/systemd/system/php-fpm.service
# It's not recommended to modify this file in-place, because it
# will be overwritten during upgrades. If you want to customize,
# the best way is to use the "systemctl edit" command.
 
[Unit]
Description=The PHP FastCGI Process Manager
After=network.target
 
[Service]
Type=simple
PIDFile=/var/run/php-fpm.pid
ExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID
PrivateTmp=true
 
[Install]
WantedBy=multi-user.target

Start php-fpm

When starting the PHP service through systemctl for the first time, you need to enable the php-fpm service first:

[root@opstrip.com php-7.1.5]# systemctl enable php-fpm.service
[root@opstrip.com php-7.1.5]# systemctl start php-fpm.service

Compile and install Nginx

See this article for details, and configure and start Nginx as needed. I won’t write it down here.

Enable MySQL extension (only compile and install)

Since PHP7 has completely removed MySQL extension support (replaced by mysqli and mysqlnd), some old software will If an error similar to that the mysql_connect() function is not defined is reported, it is generally recommended to use the new PHPmysqli or pdo extension to replace it. Of course, you can also check out the legacy version of the PHP7 code that supports the MySQL extension and compile and install it yourself. However, it should be noted that the MySQL extension has no subsequent updates at all.

Preparation before installation

View the current extension

Check the current PHP7.1 built-in extension:

[root@opstrip.com php-7.1.5]# ls ext
bcmath  dom     gd   json  oci8   pdo_firebird posix   skeleton sysvsem  xmlwriter
bz2   enchant    gettext  ldap  odbc   pdo_mysql  pspell  snmp  sysvshm  xsl
calendar  exif    gmp   libxml  opcache  pdo_oci   readline  soap  tidy   zip
com_dotnet ext_skel   hash   mbstring openssl  pdo_odbc  recode  sockets  tokenizer zlib
ctype   ext_skel_win32.php iconv  mcrypt  pcntl  pdo_pgsql  reflection spl   wddx
curl   fileinfo   imap   mysql  pcre   pdo_sqlite  session  sqlite3  xml
date   filter    interbase mysqli  pdo   pgsql   shmop   standard xmlreader
dba   ftp     intl   mysqlnd  pdo_dblib phar   simplexml  sysvmsg  xmlrpc

You can see that the MySQL extension has indeed been removed Now, we can directly check out the old PHP MySQL extension code in the ext directory.

Get the PHP MySQL extension source code

[root@opstrip.com ext]# git clone https://github.com/php/pecl-database-mysql mysql --recursive

Compile and install the MySQL extension

Compile using phpize

[root@opstrip.com ext]# cd mysql
[root@opstrip.com mysql]# ls
config.m4 config.w32 CREDITS LICENSE mysql.mak mysql_mysqlnd.h package.xml php_mysql.c php_mysql.h php_mysql_structs.h README.md tests
[root@opstrip.com mysql]# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version:   20151012
Zend Module Api No:  20151012
Zend Extension Api No: 320151012
[root@opstrip.com mysql]# ./configure --with-php-config=/usr/local/php/bin/php-config

Installation

[root@opstrip.com mysql]# make && make install
[root@opstrip.com mysql]# ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/
mysql.so opcache.a opcache.so

Required after the installation is complete Confirm whether the MySQL extension is installed correctly.

Finally modify the php.ini configuration file and add a line:

extension = "mysql.so"

Restart the php-fpm service and you will see the MySQL extension in phpinfo:

–This configuration is complete.
