Linux下啟動和停止apache服務

本文使用的Linux系統為CentOS 7，下面將介紹apache服務的啟動、關閉與設置。apache在CentOS 7中一般是默認安裝的，而且服務名字為httpd。

1. 安裝apache及查看相關配置

# apache安裝命令

$ sudo yum install httpd
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Package httpd-2.4.6-45.el7.centos.4.x86_64 already installed and latest version
Nothing to do


# 查看apache文件的位置

$ sudo find / -name httpd
/run/httpd
/etc/logrotate.d/httpd
/etc/sysconfig/httpd
/etc/httpd
/var/log/httpd
/var/cache/httpd
/usr/sbin/httpd
/usr/lib64/httpd
/usr/share/httpd
/usr/include/httpd
/usr/libexec/initscripts/legacy-actions/httpd

Apache配置文件位於/etc/httpd/conf，主要的配置文件是/etc/httpd/conf/httpd.conf, apache相關的配置信息都可以在這個文件中看到。

2. apache服務的啟動與關閉

# 啟動服務
$ sudo systemctl start httpd.service

# 查看服務
$ ps aux | grep httpd
