centos swoole


我的PHP版本为PHP 7.2.24
  1. 更新源
[root@localhost html]# yum update
  1. 安装需要支持的扩展
[root@localhost html]# yum install php72w-devel
[root@localhost html]# yum install php72w-pear
[root@localhost html]# yum install gcc
[root@localhost html]# yum install gcc-c++
[root@localhost html]# yum install gcc-g77
  1. 安装swoole
[root@localhost html]# pecl install swoole
// 是否启用 PHP Sockets 支持
enable sockets supports? [no] : yes
// 是否启用 OpenSSL 支持
enable openssl support? [no] : yes
// 是否启用 HTTP2 支持
enable http2 support? [no] : yes
// 是否启用 MySQL 原生支持
enable mysqlnd support? [no] : yes


Build process completed successfully
Installing '/usr/lib64/php/modules/swoole.so'
Installing '/usr/include/php/ext/swoole/config.h'
install ok: channel://pecl.php.net/swoole-4.4.12
configuration option "php_ini" is not set to php.ini location
You should add "extension=swoole.so" to php.ini


PHP Startup: Unable to load dynamic library 'swoole.so' (tried: /usr/lib64/php/modules/swoole.so (/usr/lib64/php/modules/swoole.so: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/swoole.so.so (/usr/lib64/php/modules/swoole.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
// 把extension=swoole.so加到socket的加载后面,在php7.2中进入/etc/php.d下,在sockets.ini中将extension=swoole.so加到extension=sockets.so下面,后重启php-fpm

php -m或者 phpinfo()查看不到swoole


1. 确认安装和配置是否有问题
2、如果使用php -m无法查看swoole,请使用命令service php-fpm restart重启
3、如果使用phpinfo()无法查看swoole,请使用命令service httpd restart重启

// 在修改配置时extension=swoole.so别放在最后,最好放在extension=sockets.so后面
  1. 修改配置
[root@localhost html]# vim /etc/php.ini
  1. 重启
[root@localhost html]# /bin/systemctl restart php-fpm.service
[root@localhost html]# /bin/systemctl restart httpd.service
  1. 验证是否安装成功
php -m 或者 phpinfo() 查看是否有swoole


[root@localhost /]# php --ri swoole
