在 CentOS 上检查 Apache

Question

I am trying to run Apache on my CentOS.(I am having very basic knowledge on linux).

[Apache Start Stop] using this link i tried to run: apachect1 start But I got -bash apachect1: command not found

I also tried to check the status using $ /etc/init.d/nginx status But I got -bash: /etc/init.d/nginx: No such file or directory

Then I tried to check if Apache is installed using : which apache2 But I got /usr/bin/which: no apache2 in (/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/git/bin:/usr/local/git/bin:/home/bebo/bin)

It seems that Apache is not installed, however I can see httpd directory in etc folder. Does it have any significance?

Is my assumption correct, if yes how can I install/from where to download & install. Else correct where I am going wrong.

Answer 1

These all the steps will be applied for CentOS 7 and CentOS 8

( Note also apply on RHEL 7/8)

I recommend running the below command to auto-remove the unused packages.

Step 1:

yum autoremove

Step 2: Now run the below command to update the CentOS

  yum update

Step 3: Installing the apache software package

yum install httpd

Step 4: Starting the apache service

The name of the Apache service is httpd. Use the below command to start and enable it at the same time in CentOS 7 or later version.

systemctl enable --now httpd

Step 5: Checking the httpd service status

systemctl status httpd

Step 6: Firewall configuration

As per now, we have to allow the HTTP service in the firewall. So, you can find the below command useful for that.

firewall-cmd --permanent --add-service http
firewall-cmd --permanent --add-service https

Now reload the firewall service,

firewall-cmd --reload

Step 7: Test the Apache server. Put the IP address of your computer or the localhost on the web-browser; it will show you the Apache server is running.

Answer 2

The best and easiest way to install apache on Centos is using the yum package manager.

Just run the following:

yum install httpd

After installation depending on your Centos version you start the Apache service as follows:

Centos 6

service httpd start

Centos 7

systemctl start httpd

Answer 3

Check if apache is installed

service httpd status

if the result is "httpd: unrecognized service" , it means not installed.

or

type your domain or ip in browser, if nothing to displayed, it means no apache installed.

Install Apache

yum -y install httpd

Start Apache service

service httpd start
