Make the startup script for httpd Installation

The httpd server installed with Yum install httpd * is under the/etc/httpd directory by default.

However, the project path is under/var/www/html by default, which can be viewed in the httpd. conf configuration file.

If you download httpd from the Internet for installation, it is different. If you need to start it, you cannot use service httpd start.

You need to go to the/apache2/bin/httpd directory. In this way, you can start

Install Apache Compression

Put the downloaded package under/usr/local/src, decompress it with tar zxvf httpd-NN.tar.gz,
CD httpd-nn
./Configure -- prefix =/usr/local/httpd
Make
Make install

Now you find that there is an extra httpd directory under/usr/local.
We can use/usr/local/httpd/bin/apachectl-k start | stop | restart to manage httpd services.
To start with the system, add a line at the end of the/etc/rc. d/init. d/rc. Local file:
/Usr/local/httpd/bin/apachectl-K start
Even so, we still cannot manage the HTTPd service. Can we use the Service to manage the HTTPd service like RPM installation?
The answer is yes. We must do the following:
Create an httpd file under/etc/rc. d/init. d/and use chmod 755 httpd to make it executable.
Add the following content to VI httpd:

Use chkconfig -- add httpd

Chkconfig -- level 2345 httpd on

In this way, httpd can use the service httpd START | stop | restart command for management,
It is started with the system in the runtime environment of 2, 3, 4, and 5.
