Compile and install from source¶

The following instructions install Percona XtraBackup {{vers}}.

1. Install Percona XtraBackup from the Git Source Tree¶

Percona uses the Github revision control system for development. To build the latest Percona Server for MySQL from the source tree, you will need git installed on your system.

You can now fetch the latest Percona XtraBackup {{vers}} sources:

$ git clone https://github.com/percona/percona-xtrabackup.git
$ cd percona-xtrabackup
$ git checkout trunk
$ git submodule update --init --recursive

2. Installation prerequisites¶

The following packages and tools must be installed to compile Percona XtraBackup from source. These might vary from system to system.

Important

To build **Percona XtraBackup {{vers}} from source, you must use cmake version 3. To check which version is currently installed, run cmake --version at a command prompt. If the version is not 3, install cmake3.

This cmake version may be available in your distribution as a separate package cmake3. For more information, see cmake.org.

Debian or Ubuntu using aptCentOS or Red Hat using yum

sudo apt install bison pkg-config cmake devscripts debconf \
debhelper automake bison ca-certificates libprocps-dev \
libcurl4-openssl-dev cmake debhelper libaio-dev \
libncurses-dev libssl-dev libtool libz-dev libgcrypt-dev libev-dev libprocps-dev \
lsb-release build-essential rsync libdbd-mysql-perl \
libnuma1 socat librtmp-dev libtinfo5 vim-common \
liblz4-tool liblz4-1 liblz4-dev zstd python-docutils

To install the man pages, install the python3-sphinx package first:

$ sudo apt install python3-sphinx

Percona Xtrabackup requires GCC version 5.3 or higher. If the version of GCC installed on your system is lower then you may need to install and enable the Developer Toolset on RPM-based distributions to make sure that you use the latest GCC compiler and development tools. Then, install cmake and other dependencies:

$ sudo yum install cmake openssl-devel libaio libaio-devel automake autoconf \
bison libtool ncurses-devel libgcrypt-devel libev-devel libcurl-devel zlib-devel \
zstd vim-common procps-ng-devel

To install the man pages, install the python3-sphinx package first:

$ sudo yum install python3-sphinx

3. Generate the build pipeline¶

At this step, you have cmake run the commands in the CMakeList.txt file to generate the build pipeline, i.e., a native build environment that will be used to compile the source code).

Change to the directory where you cloned the Percona XtraBackup repository
```
$ cd percona-xtrabackup
```
Create a directory to store the compiled files and then change to that directory:
```
$ mkdir build
$ cd build
```
Run cmake or cmake3. In either case, the options you need to use are the same.

Note

You can build Percona XtraBackup with man pages but this requires python-sphinx package which isn’t available from that main repositories for every distribution. If you installed the python-sphinx package you need to remove the -DWITH_MAN_PAGES=OFF from previous command.

$ cmake -DWITH_BOOST=PATH-TO-BOOST-LIBRARY -DDOWNLOAD_BOOST=ON \
-DBUILD_CONFIG=xtrabackup_release -DWITH_MAN_PAGES=OFF -B ..

Parameter Information¶

Parameter	Description
`-DWITH_BOOST`	For the `-DWITH_BOOST` parameter, specify the name of a directory to download the boost library to. This directory is created automatically in your current directory.
`-DWITH_MAN_PAGES`	To build Percona XtraBackup man pages, use `ON` or remove this parameter from the command line (it is `ON` by default). To install the man pages, install the python3-sphinx package first.
`-B` (–build)	Percona XtraBackup is configured to forbid generating the build pipeline for make in the same directory where you store your sources. The `-B` parameter refers to the directory that contains the source code. In this example, we use the relative path to the parent directory (..).

Important

CMake Error at CMakeLists.txt:367 (MESSAGE): Please do not build in-source. Out-of source builds are highly recommended: you can have multiple builds for the same source, and there is an easy way to do cleanup, simply remove the build directory (note that ‘make clean’ or ‘make distclean’ does not work)

You can force in-source build by invoking cmake with -DFORCE_INSOURCE_BUILD=1.

4. Compile the source code¶

To compile the source code in your build directory, use the make command.

Change to the build directory (created at Step 2: Generating the build pipeline).
Run the make command. This command may take a long time to complete.
```
$ make
```
To use all CPU threads and make compilation faster please use:
```
$ make -j$(nproc --all)
```

5. Install on the target system¶

The following command installs all Percona XtraBackup binaries xtrabackup and tests to default location on the target system: /usr/local/xtrabackup.

Run make install to install Percona XtraBackup to the default location.

$ sudo make install

Install to a non-default location¶

You may use the DESTDIR parameter with make install to install Percona XtraBackup to another location. Make sure that the effective user is able to write to the destination you choose.

$ sudo make DESTDIR=<DIR_NAME> install

In fact, the destination directory is determined by the installation layout (-DINSTALL_LAYOUT) that cmake applies (see Step 2: Generating the build pipeline). In addition to the installation directory, this parameter controls a number of other destinations that you can adjust for your system.

By default, this parameter is set to STANDALONE, which implies the installation directory to be /usr/local/xtrabackup.

6. Run Percona XtraBackup¶

After Percona XtraBackup is installed on your system, you may run it by using the full path to the xtrabackup command:

$ /usr/local/xtrabackup/bin/xtrabackup

Update your PATH environment variable if you would like to use the command on the command line directly.

$# Setting $PATH on the command line
$ PATH=$PATH:/usr/local/xtrabackup/bin/xtrabackup

$# Run xtrabackup directly
$ xtrabackup

Alternatively, you may consider placing a soft link (using ln -s) to one of the locations listed in your PATH environment variable.

To view the documentation with man, update the MANPATH variable.
