Deploying TiDB is the first lesson in front of us, in fact, there are many ways to deploy, limited to the environment, I first began to think about how to deploy the stand-alone version.

If you want to deploy in the version of Centos 6, this is still quite difficult, and there will be a lot of unknown holes, according to the official suggestion, it is necessary to be in the version of Centos 7 or above, otherwise the version of glibc will soon encounter problems.

Let's install a set of Centos7 and try it out with a quick stand-alone deployment.

Get the binary package, which is about more than 100 M.

[root@localhost ~] # wget http://download.pingcap.org/tidb-latest-linux-amd64.tar.gz [root@localhost tidb] # wget http://download.pingcap.org/tidb-latest-linux-amd64.sha256 do information matching to check whether the file is verified correctly. Sha256sum-c tidb-latest-linux-amd64.sha256 decompresses the file. Tar-xzf tidb-latest-linux-amd64.tar.gz [root@localhost tidb] # cd tidb-latest-linux-amd64 launch PD [root@localhost tidb-latest-linux-amd64] #. / bin/pd-server-- data-dir=pd-- log-file=pd.log & the critical step is to start tikv, where the vast majority of deployments fail.
