php-fpm不能正常启动的解决办法

/opt/php5/sbin/php-fpm start
Failed loading /opt/Zend_for_php5/zend/lib/php_extensions/:  /opt/Zend_for_php5/zend/lib/php_extensions/: cannot read file data: Is a directory
Failed loading /opt/Zend_for_php5/zend/lib/debugger/php-5.3.x/ZendDebugger.so:  libssl.so.0.9.8: cannot open shared object file: No such file or directory

经查看系统缺少libssl软件支持，yum安装后恢复正常。
