centos6.5，安装完xampp5.6.30，启动mysql报错，不能产生.err文件
[root@zabbix_server ~]# /opt/lampp/lampp startmysql
XAMPP: Starting MySQL…ok.
[root@zabbix_server ~]# /opt/lampp/bin/mysqld_safe_helper: Can’t create/write to file ‘/opt/lampp/var/mysql/zabbix_server.err’ (Errcode: 13 “Permission denied”)
检查目录权限
[root@zabbix_server ~]# ll /opt/lampp/var/mysql/

修改成root:root 以及 chmod 777都不生效
经反复测试，需要修改/opt/lampp目录的权限才可以
[root@zabbix_server ~]# chmod 755 /opt/lampp/
再启动xampp就正常了
[root@zabbix_server ~]# /opt/lampp/lampp startmysql
XAMPP: Starting MySQL…ok.
[root@zabbix_server ~]#
