这几天在装Apache httpd服务后，启动httpd服务，报错如下：
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 0.0.0.0 for ServerName (13)Permission denied: make_sock: could not bind to address [::]:88 (13)Permission denied: make_sock: could not bind to address 0.0.0.0:88 no listening sockets available, shutting down Unable to open logs [FAILED]发现是SELinux在作怪，查看SElinux使用状态
#getenforce EnforcingSElinux未禁用。
1、临时禁用SELinux：
# setenforce 0这样重启服务器之后，还是会启动SELinux；
备注：setenforce 1 临时启用SELinux
2、永久禁用： 打开服务器上的SELinux配置文件，默认为：/etc/selinux/config（还有/etc/sysconfig/selinux），内容如下：
#This file controls the state of SELinux on the system. #SELINUX= can take one of these three values: #enforcing - SELinux security policy is enforced. #permissive - SELinux prints warnings instead of enforcing. #disabled - SELinux is fully disabled. SELINUX=enforcing #SELINUXTYPE= type of policy in use. Possible values are: #targeted - Only targeted network daemons are protected. #strict - Full SELinux protection. SELINUXTYPE=targeted将上面的 SELINUX=enforcing 改为：SELINUX=disable 禁用SeLinux
然后启动httpd服务：
service httpd start
Starting httpd: httpd: Could not reliably determine the server’s fully qualified domain name, using 0.0.0.0 for ServerName
