Centos
Apache 不會在本地網路中的 CentOS 上啟動
我在 CentOS 7 伺服器上安裝了 httpd，但
systemctl start httpd.service失敗了。
httpd為了在 CentOS 7 上正確啟動，需要輸入什麼特定的命令序列？錯誤資訊
從底部的完整結果中提取的精確錯誤消息如下：
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message此外，根據@DopeGhoti 的建議，日誌的內容是：
[root@localhost ~]# vi /var/log/httpd/error_log (13)Permission denied: AH00091: httpd: could not open error log file /var/www/mytestdeployment/error.log. AH00015: Unable to open logs (13)Permission denied: AH00091: httpd: could not open error log file /var/www/mytestdeployment/error.log. AH00015: Unable to open logs (13)Permission denied: AH00091: httpd: could not open error log file /var/www/mytestdeployment/error.log.如何
httpd安裝：1.) 安裝 Apache：
sudo yum -y install httpd2.) 啟用 Apache 作為 CentOS 服務，以便它在重新啟動時自動重新啟動：
sudo systemctl enable httpd.service3.) 配置防火牆
sudo firewall-cmd --zone=public --add-service=http sudo firewall-cmd --list-all sudo firewall-cmd --zone=public --permanent --add-service=http4.) 給伺服器起一個名字：
vi /etc/httpd/conf/httpd.conf //Uncomment the ServerName line and give it the IP of the machine: ServerName 192.168.1.5:80錯誤資訊：
httpd使用上述命令安裝後，httpd啟動失敗如下：[root@localhost ~]# systemctl start httpd.service Job for httpd.service failed because the control process exited with error code.

在@JeffSchaller 建議考慮 SELinux 之後，我發現
setenforce 0以 root 身份輸入會導致以下結果：[root@localhost ~]# sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: enforcing Mode from config file: enforcing Policy MLS status: enabled Policy deny_unknown status: allowed Max kernel policy version: 28 [root@localhost ~]# setenforce 0 [root@localhost ~]# sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: permissive Mode from config file: enforcing Policy MLS status: enabled Policy deny_unknown status: allowed Max kernel policy version: 28 [root@localhost ~]# systemctl start httpd.service -l [root@localhost ~]# systemctl status httpd.service -l ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2017-06-06 12:28:38 PDT; 22s ago Docs: man:httpd(8) man:apachectl(8) Process: 32577 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=1/FAILURE) Main PID: 32690 (httpd) Status: "Total requests: 0; Current requests/sec: 0; Current traffic: 0 B/sec" CGroup: /system.slice/httpd.service ├─32690 /usr/sbin/httpd -DFOREGROUND ├─32691 /usr/sbin/httpd -DFOREGROUND ├─32692 /usr/sbin/httpd -DFOREGROUND ├─32693 /usr/sbin/httpd -DFOREGROUND ├─32694 /usr/sbin/httpd -DFOREGROUND └─32695 /usr/sbin/httpd -DFOREGROUND Jun 06 12:28:38 localhost.localdomain systemd[1]: Starting The Apache HTTP Server...

Apache 啟動失敗，出現錯誤提示
(13)權限被拒絕：AH00091：httpd：無法打開錯誤日誌文件/var/www/mytestdeployment/error.log。
AH00015: 無法打開日誌
由於 SELinux 處於強制模式，它阻止 Apache 寫入非標準日誌目錄。為了防止Dan Walsh 哭泣和CodeMed高效，我們可以將 httpd_log_t 策略應用於該目錄：
semanage fcontext -a -t httpd_log_t "/var/www/mytestdeployment(/.*)?" restorecon -Rv /var/www/mytestdeployment並確認：
ls -lZ /var/www/mytestdeployment如果您沒有 semanage 實用程序，您可以使用以下命令安裝它：
yum install policycoreutils-python
