添加VirtualHost conf文件後apache不會重新啟動，為什麼不呢？
在伺服器中，在底部添加包含文件後
CentOS 7鍵入時出現以下錯誤：sudo apachectl restart``httpd.confJob for httpd.service failed. See 'systemctl status httpd.service' and 'journalctl -xn' for details.當我然後鍵入
sudo systemctl status httpd.service -l時，結果是：httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled) Active: failed (Result: exit-code) since Tue 2014-12-23 20:10:37 EST; 2min 15s ago Process: 2101 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=0/SUCCESS) Process: 2099 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE) Main PID: 2099 (code=exited, status=1/FAILURE) Status: "Total requests: 0; Current requests/sec: 0; Current traffic: 0 B/sec" Dec 23 20:10:37 ip-address httpd[2099]: AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using fe80::e23f:49ff:feb7:2a21.

apache如果我註釋掉包含指令，我可以重新啟動，並且我可以通過取消註釋包含指令來重新創建錯誤 。如何apache正確開始使用包含文件的內容？
httpd.conf觸發錯誤的底部的行是：IncludeOptional sites-enabled/*.conf。.conf文件夾中唯一的sites-enabled文件是mydomain.com.conf，其內容如下：<VirtualHost *:80> ServerName www.mydomain.com ServerAlias mydomain.com DocumentRoot /var/www/mydomain.com/public_html ErrorLog /var/www/mydomain.com/error.log CustomLog /var/www/mydomain.com/requests.log combined </VirtualHost>除了上面的一行包含指令外，它
httpd.conf與預安裝的相同。httpd我知道，因為我sudo yum remove httpd mod_ssl在sudo yum install httpd mod_ssl觸發此錯誤之前就這樣做了。點擊此連結httpd.conf可在文件共享站點上閱讀全文。我在明確遵循本教程中的步驟時遇到了這個問題。
當我註釋掉包含文件時，
http/mydomain.com成功提供了位於 中的靜態內容/var/www/html，即DocumentRoot在httpd.conf. 問題似乎來自VirtualHost上面顯示的包含文件中的指令。 為了幫助診斷，我在下面的 EDIT#3 中包含了指向所有.conf文件的連結，這些文件包含在httpd.conf.編輯#1
當我嘗試將 m32 的建議更改
/etc/hostname為 definemydomain.com時，apache仍然不會重新啟動，systemctl status httpd.service結果如下：[sudo_user_account@server-ip-address ~]$ sudo systemctl status httpd.service -l httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled) Active: failed (Result: exit-code) since Tue 2014-12-23 14:25:35 EST; 20s ago Process: 31993 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=0/SUCCESS) Process: 31991 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE) Main PID: 31991 (code=exited, status=1/FAILURE) Status: "Total requests: 1; Current requests/sec: 0; Current traffic: 0 B/sec" Dec 23 14:25:35 hostname systemd[1]: httpd.service: main process exited, code=exited, status=1/FAILURE Dec 23 14:25:35 hostname systemd[1]: Failed to start The Apache HTTP Server. Dec 23 14:25:35 hostname systemd[1]: Unit httpd.service entered failed state.編輯#2
我還嘗試了 eyoung100 的建議來更改我的
/etc/hosts文件的內容，如下圖所示，但我仍然遇到上面 EDIT#1 中定義的相同錯誤。
編輯#3
根據 DerekC 的要求，我執行
sudo apachectl configtest並得到：AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using fe80::e23f:49ff:feb7:2a21. Set the 'ServerName' directive globally to suppress this message Syntax OK此外，根據 GarethTheRed 的建議，我檢查了httpd.conf中的包含指令。httpd.conf中有三個包含指令。我列出了下面三個，以及位於每個指令文件夾中的所有文件。這些都是
.conf隨httpd. 我還沒有修改任何一個。您可以.conf通過點擊以下連結在文件共享站點查看每個文件：
Include conf.modules.d/*.conf引用目錄中的以下文件conf.modules.d： 00-base.conf
IncludeOptional conf.d/*.conf引用目錄中的以下文件conf.d： autoindex.conf還有一個我在這裡省略的README 文件。
此外，該
IncludeOptional sites-enabled/*.conf指令及其內容已在上述 OP 中進行了全面概述。這些包含文件是否與 中的
VirtualHost設置衝突mydomain.com.conf？編輯#4
根據 garethTheRed 的建議，我移至
mydomain.com.conf目錄conf.d，然後開始逐行註釋掉行，mydomain.com.conf直到httpd能夠重新啟動。然後我開始取消註釋行，看看有多少行可以保留並且httpd仍然重新啟動。我能夠httpd重新啟動，但systemctl status httpd.service -l繼續產生相同的警告：AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using fe80::e23f:49ff:feb7:2a21. Set the 'ServerName' directive globally to suppress this message
VirtualHost允許啟動的語法httpd（儘管繼續生成上述警告）如下：<VirtualHost *:80> ServerName www.mydomain.com ServerAlias mydomain.com DocumentRoot /var/www/mydomain.com/public_html </VirtualHost>請注意，我必須省略以下幾行，它們的存在會將警告升級為完全無法啟動 http：
# ErrorLog /var/www/mydomain.com/error.log # CustomLog /var/www/mydomain.com/requests.log combined另外，我跑
sudo journalctl -xelu httpd了，終端通過重複以下多次回复：-- -- Unit httpd.service has finished shutting down.

日誌導致錯誤，因為
apache無法寫入您網站的根目錄。即使您要修復文件權限，您仍然會被 SELinux 阻止；僅允許apache將日誌寫入/var/log/httpd. 最簡單的解決方案是將您的網站更改為登錄到此目錄 - 可能使用包含網站名稱的文件名，以便將其與其他日誌區分開來。ErrorLog /var/log/httpd/mydomain_com_error.log CustomLog /var/log/httpd/mydomain_com_requests.log combined要設置伺服器的主機名並消除 AH00558 警告，只需使用：
hostnamectl set-hostname --static <FQDN of your machine>例如
hostnamectl set-hostname --static mydomain.com
