http服务启动时的两个错误

本人系统CentOS 6.5 64bit， Apache HTTP Server的版本为2.2.15。

启动http服务时出现如下错误:

[root@lls ipc]# /etc/init.d/httpd startStarting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using lls.pc for ServerName(13)Permission denied: make_sock: could not bind to address [::]:8099(13)Permission denied: make_sock: could not bind to address 0.0.0.0:8099no listening sockets available, shutting downUnable to open logs                                                           [FAILED]

错误原因在于SELinux 安全机制的作用，现在来逐个解决问题。

Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using lls.pc for ServerName

表示没有确切地定义主机名。

在配置文件/etc/httpd/conf/httpd.conf中修改,将被注释掉的ServerName名字改为自己的主机名，查看主机名:

[root@lls ipc]# hostnamells.pc

于是将被屏蔽掉的ServerName修改为:

ServerName lls.pc

(13)Permission denied: make_sock: could not bind to address [::]:8099(13)Permission denied: make_sock: could not bind to address 0.0.0.0:8099no listening sockets available, shutting downUnable to open logs

表示系统系统中没有为http服务定义8099端口，查看http端口:

[root@lls ipc]# semanage port -l | grep httphttp_cache_port_t              tcp      3128, 8080, 8118, 8123, 10001-10010http_cache_port_t              udp      3130http_port_t                    tcp      80, 81, 443, 488, 8008, 8009, 8443, 9000pegasus_http_port_t            tcp      5988pegasus_https_port_t           tcp      5989

查看http_port_t，系统果然没有为http服务定义8099端口，于是添加8099端口并再次查看http服务的端口:

[root@lls ipc]# semanage port -a -t http_port_t -p tcp 8099[root@lls ipc]# semanage port -l | grep httphttp_cache_port_t              tcp      3128, 8080, 8118, 8123, 10001-10010http_cache_port_t              udp      3130http_port_t                    tcp      8099, 80, 81, 443, 488, 8008, 8009, 8443, 9000pegasus_http_port_t            tcp      5988pegasus_https_port_t           tcp      5989

可以看到，在http_port_t中增加了8099。

重新启动http服务:

[root@lls ipc]# /etc/init.d/httpd startStarting httpd:                                            [  OK  ]

Ok,启动成功。
