php安装event扩展

用于centos7的php7 workerman环境

1.安装libevent和event扩展

​yum install libevent -y

yum install libevent-devel -y
 
pecl install event

 

2.查看php配置文件位置

php --ini

3.添加扩展

extension=sockets.so
extension=event.so

4.注释socket.ini的extension=socket.so

 

 

操作中出现的问题

1.使用pecl安装event扩展报错

configure: error: Please reinstall the event library, or provide the installation prefix via --with-event-libevent-dir option

原因是未安装 libevent 或 libevent-devel 库

 

2.安装扩展后启动workerman报错

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/event.so' - /usr/lib64/php/modules/event.so: undefined symbol: php_sockets_le_socket in Unknown on line 0

原因是扩展加载顺序的问题

1.注释sockets.ini的extension=sockets.so

2.php.ini添加extension=sockets.so和extension=event.so
