This section describes how to install MySQL from the latest development source code, which is hosted on GitHub. To obtain the MySQL Server source code from this repository hosting service, you can set up a local MySQL Git repository.
MySQL officially joined GitHub in September, 2014. For more information about MySQL's move to GitHub, refer to the announcement on the MySQL Release Engineering blog: MySQL on GitHub
To install MySQL from a development source tree, your system must satisfy the tool requirements listed at Source Installation Prerequisites.
To set up a MySQL Git repository on your machine:
Clone the MySQL Git repository to your machine. The following command clones the MySQL Git repository to a directory named
mysql-server. The initial download may take some time to complete, depending on the speed of your connection.
~$ git clone https://github.com/mysql/mysql-server.git Cloning into 'mysql-server'... remote: Counting objects: 1035465, done. remote: Total 1035465 (delta 0), reused 0 (delta 0) Receiving objects: 100% (1035465/1035465), 437.48 MiB | 5.10 MiB/s, done. Resolving deltas: 100% (855607/855607), done. Checking connectivity... done. Checking out files: 100% (21902/21902), done.
When the clone operation completes, the contents of your local MySQL Git repository appear similar to the following:
~$ cd mysql-server ~/mysql-server$ ls client extra mysys storage cmake include packaging strings CMakeLists.txt INSTALL plugin support-files components libbinlogevents README testclients config.h.cmake libbinlogstandalone router unittest configure.cmake libmysql run_doxygen.cmake utilities Docs libservices scripts VERSION Doxyfile-ignored LICENSE share vio Doxyfile.in man sql win doxygen_resources mysql-test sql-common
Use the git branch -r command to view the remote tracking branches for the MySQL repository.
~/mysql-server$ git branch -r origin/5.5 origin/5.6 origin/5.7 origin/8.0 origin/HEAD -> origin/8.0 origin/cluster-7.2 origin/cluster-7.3 origin/cluster-7.4 origin/cluster-7.5 origin/cluster-7.6
To view the branch that is checked out in your local repository, issue the git branch command. When you clone the MySQL Git repository, the latest MySQL GA branch is checked out automatically. The asterisk identifies the active branch.
~/mysql-server$ git branch * 8.0
To check out an earlier MySQL branch, run the git checkout command, specifying the branch name. For example, to check out the MySQL 5.7 branch:
~/mysql-server$ git checkout 5.7 Branch 5.7 set up to track remote branch 5.7 from origin. Switched to a new branch '5.7'
To obtain changes made after your initial setup of the MySQL Git repository, switch to the branch you want to update and issue the
~/mysql-server$ git checkout 5.7 ~/mysql-server$ git pull
To examine the commit history, use the
~/mysql-server$ git log
You can also browse commit history and source code on the GitHub MySQL site.
After you have cloned the MySQL Git repository and have checked out the branch you want to build, you can build MySQL Server from the source code. Instructions are provided in Chapter 2, Installing MySQL Using a Standard Source Distribution, except that you skip the part about obtaining and unpacking the distribution.
Be careful about installing a build from a distribution source tree on a production machine. The installation command may overwrite your live release installation. If you already have MySQL installed and do not want to overwrite it, run CMake with values for the
MYSQL_UNIX_ADDRoptions different from those used by your production server. For additional information about preventing multiple servers from interfering with each other, see Running Multiple MySQL Instances on One Machine.
Play hard with your new installation. For example, try to make new features crash. Start by running make test. See The MySQL Test Suite.
