Did you already lost hours because you lost your information to connect to a server after months not using it?<\/p>\n\n\n\n

If it is the case what we will detail in this article will interest you for sure and make you save time for sure.<\/p>\n\n\n\n

The problem<\/h2>\n\n\n\n

Most of time, as a developer we have multiple servers we have to interact with. However our brain has limited capacities and this can rapidly become a mess when we have to interact with server we didn\u2019t worked with since a week or a month.<\/p>\n\n\n\n

Often the IP of the server is lost in a mountain of commands and it can be even worse for the key used to connect to the server which can be lost somewhere on the filesystem.<\/p>\n\n\n\n

This two problems are a certainly small but really repetitive and over a year it is hours to days you are loosing.<\/p>\n\n\n\n

Giving to the IP a name<\/h2>\n\n\n\n

The first problem we will be solving is the problem with the IP of the server.<\/p>\n\n\n\n

What we will do is that we will give it a name that we can remember later.<\/p>\n\n\n\n

For that we will have to edit the file \/etc\/hosts<\/em><\/strong> and add this line where:<\/p>\n\n\n\n

    \n
  • xxx.xxx.xxx.xxx<\/em><\/strong>\u00a0is your IP.<\/li>\n\n\n\n
  • server_name<\/em><\/strong>\u00a0is the name you want to give it.<\/li>\n<\/ul>\n\n\n\n
    xxx.xxx.xxx.xxx  server_name<\/code><\/pre>\n\n\n\n
    Once we have set this now instead of using the ip in our ssh command we can use the name we gave it which is a way easier to remember.<\/p>\n\n\n\n
    Saving login details<\/h2>\n\n\n\n
    The second thing to do is to find a way to remember our key everytime we connect to the server.<\/p>\n\n\n\n
    For that we will use ssh configuration file which will help us to set a default password for the server.<\/p>\n\n\n\n
    For that we will have to add content or create ~\/.ssh\/config.<\/p>\n\n\n\n
    To connect to the server then you add the following content:<\/p>\n\n\n\n
    Host server_name
       HostName server_name
       User root
       Port 22
       IdentityFile ~\/server_name.pem<\/code><\/pre>\n\n\n\n
    Where:<\/p>\n\n\n\n
      \n
    • server_name<\/em><\/strong>\u00a0is the name or the IP of the server.<\/li>\n\n\n\n
    • ~\/server_name.pem<\/em><\/strong>\u00a0is the path to the key to connect to the server.<\/li>\n<\/ul>\n\n\n\n
      Now that you know this you won\u2019t have anymore to search for your login when you have to connect to a server by SSH.<\/p>\n\n\n\n
      I hope you enjoyed this tutorial and it will be useful for you in the future.<\/p>","protected":false},"excerpt":{"rendered":"
