Detailed tutorial on installing Swoole in PHP7

Environment

Apache is not used as the web server here. Use nginx php-fpm, which has more powerful performance and easier configuration. And in order to keep up with the pace of PHP, a relatively new PHP version is also used

[x] centos7

[x] php7.0.12

[x] nginx/1.10.2

[x] php-fpm

Download swoole

First download the swoole source code package, this operation is very Simple, not much to say.

wget -c https://github.com/swoole/swoole-src/archive/v2.0.6.tar.gz

Unzip:

tar -zxvf v2.0.6.tar.gz
cd swoole-src-2.0.6/

Compile & Install

Use phpize to generate php compilation configuration

./configure to compile Configuration detection

make to compile, make install to install

Command execution:

[root@php7 swoole-src-2.0.6]# phpize
[root@php7 swoole-src-2.0.6]# ./configure
[root@php7 swoole-src-2.0.6]# make && make install

After make install, if correct, the following content will appear

[root@php7 swoole-src-2.0.6]# make install
Installing shared extensions:     /usr/lib64/php/modules/

This means that the swoole.so file was successfully generated in the /usr/lib64/php/modules/ directory

Modify the configuration file

To be able to use the module, You also need to add this module in the php.ini file.

It should be noted here that the module configuration files of php7 are separated separately.

The following content can be found in php.ini

;;;; 
; Note: packaged extension modules are now loaded via the .ini files 
; found in the directory /etc/php.d; these are loaded by default. 
;;;;

Therefore, if your php is installed without special settings, you can find the added module in the /etc/php.d directory configuration file.

Enter the cd /etc/php.d directory and complete the relevant configuration

[root@php7 swoole-src-2.0.6]# vim swoole.ini

; Enable swoole extension module
extension=swoole.so

Restart the service

After adding the php module, you need to restart It will take effect only after starting the service. If sometimes it still doesn't work after restarting, please close it first and then restart it.

[root@php7 swoole-src-2.0.6]# systemctl restart nginx
[root@php7 swoole-src-2.0.6]# systemctl restart php-fpm

Check whether swoole is successfully loaded through php -m or phpinfo()

Automatic prompt of swoole code

After installing the extension, it’s a matter of use. Since there is no code prompt, it is sometimes very inconvenient. Someone on github has provided ide-helper for swoole code prompts. The specific setting method is as follows:

Here is: phpStorme as an example, download the code to the local

git clone git@github.com:eaglewu/swoole-ide-helper.git ide-helper

After the above steps, you can use swoole in phpStorme. And provide code tips.

Simple test

All test codes are placed here

Please clone the code locally to facilitate observation of the effect.

git clone git@github.com:helei112g/learn-swoole.git

The code example demo1-serv provided in this section

Enter the test code directory,

Then use telnet on the server to test

First, run the server-side listening program

php demo1-serv.php

After executing this command, the server will display:

Client: Connect.

Open another terminal and use telnet to connect to the current server-side listening port. And enter some text and observe the changes in the terminal.

[root@php7 ~]# telnet 127.0.0.1 9999

Hi!
Server: Hi!

This is just a simple simulated reply. Whatever the client sends, the server responds.

Exit telnet and observe what the server will display

Close the window directly, or:

[root@php7 ~]# Ctrl+]
[root@php7 ~]# telnet> quit

At this time, you will see on the service side:

Client: Close.

PS: If telnet is not installed in the test environment, please google to install it yourself.
