[Installing PHP] How to compile and install PHP7 under openSUSE42.1

First of all, I recommend an article php 7 Release Date Arrived: Will Developers Adopt PHP 7? - PHP Classes blog. It talks about whether I will use PHP7. Personally, I will use it without hesitation, but the production environment is not my decision, so I can only update the PHP version in my own development environment. So, what about you?

First of all, I recommend an article php 7 Release Date Arrived: Will Developers Adopt PHP 7? - PHP Classes blog.

It talks about whether I will use PHP7. Personally, I will use it without hesitation, but I don’t have the final say in the production environment, so I can only update the PHP version in my own development environment. . So, what about you?

The author is using the openSUSE42.1 distribution of Linux. There is no installation package for PHP7 in Yast, so I can only compile and install it manually. As a PHP developer, I really hope to learn how to compile and install PHP7. I have tried it several times before, but every time I install it, I have to go online to find various information. So, after the successful installation this time, I want to go through my own installation process. And record the problems encountered so that you can refer to them later and share them with those who need them.

Download the source code and unzip it

Getting to the point, to compile and install PHP7, you must first download the source code of PHP7. You can clone it on github or download it from the PHP official website. After downloading, extract it to the /usr/local/src directory and rename the directory to php7. Enter the directory.

Configure compilation parameters

Generate configuration file

When executing the above command, you will encounter some prompts about missing dependencies. The dependency problems I encountered are listed below:

zypper <span style="color: #0000ff;">install</span> librecode-devel

In general, when configuring, if you encounter something that is not available, open Yast and search for it. If it exists, install it, and then recompile to see what else is needed. If you can’t find it in Yast, then search online on Google .

Compile and install PHP7

<span style="color: #0000ff;">make</span> && <span style="color: #0000ff;">make</span> <span style="color: #0000ff;">install</span>

Among them, you can choose make test after make. It's just an optional step. I don't know if there will be any problems if you don't execute it, but I haven't encountered it yet.

View the PHP7 directory after successful installation

After successful compilation and installation, check the PHP7 installation directory `ls /usr/local/php7`:

Set up PHP7 configuration file

<span style="color: #0000ff;">cp</span> /usr/local/src/php7/php.ini-production /usr/local/php7/etc/<span style="color: #000000;">php.ini
</span><span style="color: #0000ff;">cp</span> /usr/local/src/sapi/fpm/init.d.php-fpm /etc/init.d/php-<span style="color: #000000;">fpm
</span><span style="color: #0000ff;">cp</span> /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-<span style="color: #000000;">fpm.conf
</span><span style="color: #0000ff;">cp</span> /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf

Set environment variables

Add

to the last line of the /etc/profile file

export PATH=/usr/local/php7/bin:/usr/local/php7/sbin:$PATH

Then execute source /etc/profile

Set the PHP log directory and php-fpm process file (php-fpm.sock) directory

<span style="color: #0000ff;">mkdir</span> -p /var/log/php-fpm/ && <span style="color: #0000ff;">mkdir</span> -p /var/run/php-fpm && cd /var/run/ && <span style="color: #0000ff;">chown</span> -R nginx:nginx php-fpm

Set PHP to start at boot

<span style="color: #0000ff;">chmod</span> +x /etc/init.d/php-<span style="color: #000000;">fpm
chkconfig php</span>-fpm on

You can use the chkconfig command to view the list of startup services.

Start PHP service

service php-fpm start

Check whether PHP is started successfully through ps aux | grep 'php'

At this point, PHP7 has been installed successfully, and you can start using PHP7!
