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
Enforcing
SElinux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
[ OK ]
