How to install the php thread extension on Linux?

Ubuntu PHP installation pthreads extension:

pthreads is a PHP extension that uses multi-threading. I won’t introduce too much here. I believe that since you have already understood it, if you don’t understand, just read the documentation.

Document address: https://www.php.net/manual/zh/book.pthreads.php

Let’s talk about the installation process here. There are some twists and turns, and I also consulted a lot of information. , was officially installed. Write it down to keep your own record, and also give future friends a reference to avoid pitfalls.

Installation environment

• Ubuntu 16.04 LTS
• Lnmp 1.4 - - I believe many people are using this
• pthreads source code

It should be noted here that this extension cannot be installed successfully through pecl install pthreads. You need to download the source code, compile and install it yourself, and it can only be downloaded from the GitHub trunk branch. Other source codes seemed to have problems. I first downloaded them from http://pecl.php.net, but the compilation always failed. Later, I checked the information and found that there was a problem. You need to download it from GitHub.

Configuring the PHP environment

By default, everyone has already installed the lnmp environment. If it is not installed properly, please turn left when you go out and Google it.
Because pthreads requires PHP to run in a thread-safe manner, you need to add --enable-maintainer-zts when compiling PHP. However, the lnmp integration package is thread-unsafe by default.

Here go to your lnmp installation directory and find a lnmp.conf file

Add --enable-maintainer-zts in PHP_Modules_Options, just like my screenshot .

Compile PHP

1. New installation environment, just follow the lnmp process step by step. After the installation is complete, php is thread-safe.
2. Installed lnmp environment Here we can use the upgrade script provided by lnmp to upgrade php (PS: The script does not detect the current version number. If we enter the current version number, Just reinstall PHP) The operation is completed.
3. ** Manually compile PHP ** Enter the lnmp1.4-full/src directory (according to your actual situation), my directory is in /home/src/lnmp1.4-full/src and see if there is any PHP compressed package, if you haven’t downloaded one yourself

sudo wget http://cn2.php.net/distributions/php-7.0.20.tar.bz2
tar -jxvf php-7.0.20.tar.bz2

Note: You can get the address by yourself from the PHP official website. What I give here is currently available.

Continue:

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-config-file-scan-dir=/usr/local/php/conf.d --enable-fpm --with-fpm-user=www --with-fpm-group=www --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir=/usr/local/freetype --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-mbregex --enable-mbstring --enable-intl --enable-pcntl --with-mcrypt --enable-ftp --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --disable-fileinfo --enable-opcache --with-xsl --enable-maintainer-zts
make
sudo make install

This code is extracted from lnmp1.4-full/include/php.sh. You can study it yourself.
Open phpinfo();

Confirm that Thread Safety is enabled.

Compile pthreads The critical moment has come

Compile pthreads The source code package is placed in the ext directory of the php source code. My directory is: lnmp1.4-full\src\php-7.0.19\ext [Adjust according to your own situation]
Enter the pthreads directory

phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
sudo make install

php-config path is adjusted according to your own situation. If you are using the default lnmp, this is it

When executed here, a message indicating that pthreads.so was successfully compiled should appear. If not, check the previous steps.

Configuring php.ini

General online tutorials will say after reaching this point: Add pthreads.so to the php.ini file and restart php-fpm and that's it.
This is a pit. If you add php.ini directly, you will find that php-fpm cannot be started, and it prompts that pthreads.so cannot be loaded.

Correct posture:
Copy php.ini and name it php-cli.ini
Put pthreads.so into php.cli.ini
Then php -m | grep pthreads to see if it has appeared.

It is complete only at this point.

Note: Do not use pthreads in a production environment If there are bugs, just play with it yourself and run command line tasks. Through the final installation, you also discovered that it can only be run through the cli. Ha ha ha ha.

Finally, a reminder, there are many demos in the windows installation pthreads package that you can view.
