centos7中在通过同个ip，使用不同的端口启动http服务时，出现以下错误。 [root@localhost user]# systemctl restart httpd.service Job for httpd.service failed because the control process exited with error code. See “systemctl status httpd.service” and “journalctl -xe” for details.

原因：seLinux阻止8081端口启动 解决方法：
输入这两条指令： [root@localhost user]# ausearch -c ‘httpd’ –raw | audit2allow -M my-httpd libsepol.sepol_string_to_security_class: unrecognized class dir libsepol.sepol_string_to_security_class: unrecognized class tcp_socket ********** IMPORTANT ************* To make this policy package active, execute:
semodule -i my-httpd.pp
[root@localhost user]# semodule -i my-httpd.pp [root@localhost user]# systemctl restart httpd.service
