为workerman安装支持更大并发数所需的event扩展

发布时间：2021-11-27 20:44:18编辑：雪饮阅读（）

 我的linux环境：

[root@localhost sockets]# cat /etc/redhat-release
CentOS Linux release 7.8.2003 (Core)
安装event扩展依赖的libevent-devel包
yum install libevent-devel -y
pecl config-set php_bin /usr/local/php734/bin/php 
pecl config-set ext_dir /usr/local/php734/lib/php/ext
pecl config-set php_ini /usr/local/php734/lib/php/php.ini
[root@localhost workerman]# pecl install event
WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
Could not download from "https://pecl.php.net/get/event-3.0.6.tar", cannot download "pecl/event" (Connection to `ssl://pecl.php.net:443' failed: Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP?)
Error: cannot download "pecl/event"
Download failed
install failed
安装openssl扩展（php源代码目录中找）
cd /usr/local/php-7.3.4/ext/openssl
/usr/local/php734/bin/phpize
./configure --with-php-config=/usr/local/php734/bin/php-config
[root@localhost openssl]# ls /usr/local/php734/lib/php/extensions/no-debug-non-zts-20180731/
opcache.a  opcache.so  openssl.so  redis.so
php.ini中extension那一片新增配置：
extension=/usr/local/php734/lib/php/extensions/no-debug-non-zts-20180731/openssl.so
如果还是这样：
[root@localhost workerman]# pecl install event
WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
Could not download from "https://pecl.php.net/get/event-3.0.6.tar", cannot download "pecl/event" (Connection to `ssl://pecl.php.net:443' failed: Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP?)
Error: cannot download "pecl/event"
Download failed
install failed
则可以按其提示自己下载自己编译：
[root@localhost ext]# wget https://pecl.php.net/get/event-3.0.6.tar
--2021-11-27 07:13:59--  https://pecl.php.net/get/event-3.0.6.tar

2021-11-27 07:17:23 (6.31 KB/s) - ‘event-3.0.6.tar’ saved [1255424/1255424]
编译event扩展
tar -xvf event-3.0.6.tar
cd event-3.0.6
/usr/local/php734/bin/phpize
./configure --with-php-config=/usr/local/php734/bin/php-config
这里可能提示你大概意思是你需要有sockets扩展安装，同样这个扩展也在源代码目录中能找到
cd /usr/local/php-7.3.4/ext/sockets
/usr/local/php734/bin/phpize
./configure --with-php-config=/usr/local/php734/bin/php-config
make && make install
同样php.ini中extension段要新增：
extension=/usr/local/php734/lib/php/extensions/no-debug-non-zts-20180731/sockets.so
然后回到上面没有编译成功的event目录再次编译安装：
./configure --with-php-config=/usr/local/php734/bin/php-config
make && make install
那么同样的，最后再增加extension：
extension=/usr/local/php734/lib/php/extensions/no-debug-non-zts-20180731/event.so
至此evetn扩展就有了
[root@localhost workerman]# php -c /usr/local/php734/lib/php/php.ini -m
