How to install WEBSPHERE5.1 in LINUX

The correct method for installing WebSphere 5.1 in LINUX-Linux Enterprise Application-Linux server application information. For details, refer to the following section. 1. Preparations before installation
1) Check disk space allocation
2) Are there any port conflicts?
The default ports occupied by the WebSphere Application Server include: Management Console port 9090, Management Console Security Port 9043, HTTP transmission port 9080, and HTTPS transmission port 9443, SOAP communication port 8880 (in the network deployment version, this port is 8879. If an application occupies these ports in the system, the application server reports a port burst error when it starts. Generally, you can use netstat or nmap to view the usage of system ports.
3) Host Name of the server
You should configure the Host Name (hostname) before installing Websphere ). The/etc/hosts file must have corresponding entries.
4) create a user name and user group
The WebSphere Application Server has a built-in WebSphere MQ-based JMS server. During installation on UNIX/LINUX platforms, if you choose to install fully or choose to install "embedded message transmission" during custom installation ", create two user groups mqm and mqbrkrs and one user mqm before the installation starts. In addition, you need to add the user mqm and root to the mqm group, and add the root to the mqbrkrs group.
Groupadd mqm
Groupadd mqbrkrs
Useradd-g mqm
Lgroupmod-M root mqm
Lgroupmod-M root mqbrkrs
You can also use the user management tool rfuser to complete the above work.
Note that after the operation, the root user needs to log on again to make the group information take effect.
5) Language Environment Settings
During installation, use the Chinese language environment instead of en_US before installation, and switch to Chinese after installation. Such a switchover may cause system instability.
