Centos7安装swoole扩展操作示例

[root@localhost html]# yum update

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

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

安装成功

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

安装失败

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

解决方法：

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

PHP Warning: Module 'swoole' already loaded in Unknown on line 0 // 在修改配置时extension=swoole.so别放在最后，最好放在extension=sockets.so后面

修改配置

[root@localhost html]# vim /etc/php.ini ... extension=swoole.so ....

重启

[root@localhost html]# /bin/systemctl restart php-fpm.service [root@localhost html]# /bin/systemctl restart httpd.service

验证是否安装成功

php -m 或者 phpinfo() 查看是否有swoole

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