These are the steps to install OpenLiteSpeed with lsphp81 on CentOS replacements like AlmaLinux 8 or RockyLinux 8.
First add LiteSpeed repositories for AlmaLinux 8 & CentOS 8 with following command:
rpm -Uvh http://rpms.litespeedtech.com/centos/litespeed-repo-1.1-1.el8.noarch.rpm
After you have installed the rpm package you will get /etc/yum.repos.d/litespeed.repo repo file which you will need to edit in order to avoid getting the following error when installing or updating packages with yum/dnf.
Invalid configuration value: failovermethod=priority in /etc/yum.repos.d/litespeed.repo; Configuration: OptionBinding with id "failovermethod" does not exist
This will happen because the ‘failovermethod’ option is not supported by dnf which comes with RHEL 8.
Comment out that line from /etc/yum.repos.d/litespeed.repo with following command:
sed -i 's/failovermethod=priority/#failovermethod=priority/' /etc/yum.repos.d/litespeed.repo
Install OpenLiteSpeed with following command:
dnf install openlitespeed
After you have installed OpenLiteSpeed install Extra Packages for Enterprise Linux (EPEL) repository with following command:
dnf install epel-release
After that install PHP 8.1 for OpenLiteSpeed with most commonly used packages:
dnf install lsphp81 lsphp81-common lsphp81-mysqlnd lsphp81-gd lsphp81-process lsphp81-mbstring lsphp81-xml lsphp81-opcache
If you wish to install a different version of PHP just replace lsphp81 with lsphp80 for PHP 8.0 or lsphp74 for PHP 7.4 and similar.
By default OpenLiteSpeed will run on port 8088 and its WebAdmin Console will run on port 7080.
OpenLiteSpeed WebAdmin Console will have default username admin but the admin password will be randomly generated.
If you want to reset OpenLiteSpeed admin password you can run /usr/local/lsws/admin/misc/admpass.sh script which can be used to set admin password to desired value.
If you run the script it will use username admin if you don’t specify any and will then ask you to input a new password for OpenLiteSpeed administration web interface.
/usr/local/lsws/admin/misc/admpass.sh Please specify the user name of administrator. This is the user name required to login the administration Web interface. User name [admin]: Please specify the administrator's password. This is the password required to login the administration Web interface. Password: Retype password: Administrator's username/password is updated successfully!
