在centos中，配置httpd为服务，自动启动

1、创建服务文件 

vi /lib/systemd/system/httpd.service

[Unit]

Description=httpd

After=network.target

[Service]

Type=forking

ExecStart=/home/program/httpd/bin/apachectl start

ExecReload=/home/program/httpd/bin/apachectl restart

ExecStop=/home/program/httpd/bin/apachectl stop

PrivateTmp=true

[Install]

WantedBy=multi-user.target

2、自动启动

systemctl enable httpd

3、启动和停止

systemctl start httpd
systemctl status httpd

4、若修改/lib/systemd/system/httpd.service文件后，需要执行下面代码才算生效

systemctl daemon-reload
