Hi All ,
I need help of a clear "step by step" how to install and configure Zulip Chat Server,if there is any other suggestions better than Zulip please let me know. Thanks all

First, you need to read the LQ Rules, and the "Question Guidelines" and "How to ask a smart question" links in my posting signature. We are not going to look up and re-type a how-to guide for you. We are happy to help with specific questions, but if you need a how-to guide, your first step needs to be reading the instructions that come WITH that software.

Secondly, Zulip is not free or open-source; it is commercial, if you looked at their website. If you're paying, call them. If you're using their free web-based chat, there is nothing TO 'install and configure'. Sign in and use it. If you're talking about what is released on github, there are (again) instructions on their page; read them. Otherwise, there are several other chat servers for Linux, openfire being a good one. Again, you can put "linux based open source chat servers" into Google and find many.

Openfire is typically what you first will run into for a self-hosted server.
however I'd suggest Prosody since it has some very light-weight dependences (lua-based)

The general suggestions are

• Gajim (Desktop Client)
• Conversations (Android)
• ChatSecure (IOS)

agouba, nobody is getting paid to provide support, here on LQ.
LQ is not a help desk for a product you purchased.
Demanding a step-by-step is the wrong way.

you need to

• ask politely
• provide deatils about your current situation
• generally show us that you are willing to do your part in solving the problem - preferably by showing us what you already tried to tackle the problem
