Centos7.4 server installation of apache and solutions to problems encountered during the installation process
|
This article describes how to install Apache on a CentOS 7.4 server and how to solve problems that arise during the installation process. Share with you for your reference, the details are as follows: 1. Install httpd 1. Before installation, check whether there is an installed httpd.rpm package in the system. If not, it is not installed. If yes, delete it with rpm -e corresponding rpm package name. #rpm -qa | grep httpd 2. Use yum to install (automatically install dependent packages), simple and convenient #yum -y install httpd 3. After successful installation, use httpd-v to check the installed Apache version and find the location of the Apache configuration file #find / -name "httpd.conf" 4. Back up the source configuration file to prevent failure in recovery #cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.bak 5. Start Apache service #systemctl start httpd.service 6. Automatically start the Apache service at boot #systemctl enable httpd.service Start httpd automatically at boot #systemctl disable httpd.service Do not start httpd at boot 7. Check the status of httpd #systemctl status httpd.service 2. Problems during installation 1. Apache failed to start. Job for httpd.service failed because the control process exited with error code. See “systemctl status httpd.service” and “journalctl -xe” for details Execute the command and check the error message #systemctl status httpd.service
[root@cloud1 bin]# systemctl status httpd.service

The problem is that port 80 is occupied Solution: Check the usage of port 80 ① .
Kill the process occupying port 80 ② . ③. If the first two methods do not work, restart and then start the httpd service 2. Apache failed to start, httpd: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName ①. Enter the Apache configuration file vi /etc/httpd/conf/httpd.conf ② ./ServerName Find ServerName #ServerName www.example.com:80 Remove the # in front of it ③.
