Found that someone plagiarized my article, unexpectedly did not write the source, think about it is also very happy, will also be plagiarized, used to be plagiarized in junior high school is to copy other people's homework. I have changed this article many times, and that guy copied the code that was a little bit bug before. I hope he will copy it again after he sees it, so as not to mislead the children.

Recently, a new project needs to use MongoDB's Master,Slave,Arbiter architecture. I went to the official website to look through the documents and wrote a rudimentary script. The script can find https://github.com/sangrealest on my github.

Make sure that dns is set up in advance, or that the hosts file is set up before installation. The firewall should make the corresponding rules, or turn off the firewall.

First generate the certificate file for mongodb, then copy it to the Master, Slave, Arbiter directory, and add it to the configuration file.
