Install the latest version of git on CentOS

Git is available in many Linux system libraries and can be directly installed using command lines. For example, you can directly use yuminstallgit in Fedora. for details, see Debian/Ubuntu $ apt-getinstallgitFedora $ yuminstallgitGentoo $ emerge -- ask -- verbosedev-vc.

The new version of CentOS later seems to support this function, but this method is simple, but the version updates in the general repository are not timely. for example, the latest version of git in the CentOS repository is 1.7.1, however, git is officially available in version 2.x. For systems that want to obtain the latest git, only the rpm package or source code can be used.

The procedure is as follows:

1. download the compilation tool

Yum groupinstall "Development Tools"

2. download the dependency package

Yum install zlib-devel perl-ExtUtils-MakeMaker asciidoc xmlto openssl-devel

3. download the source code of the latest version of git.

Wget http://www.codemonkey.org.uk/projects/git-snapshots/git/git-latest.tar.gz

Or

Wget http://www.codemonkey.org.uk/projects/git-snapshots/git/git-latest.tar.xz

4. extract the source file

Tar-zxvf git-latest.tar.gz

Or

Xz-d git-latest.tar.xz

Tar-xvf git-latest.tar

5. Compile and install

Autoconf

./Configure

Make-jn & make-jn install

Here, n in make-j n is the specified number of threads. for multi-core processors, this can speed up compilation and installation.

6. add link

Ln-s/usr/local/bin/git/usr/bin/

This step is very important for systems with old git versions in the original system. it will be reported that the Link already exists. in this case, delete the original Link, namely/usr/bin/git, and then execute step 6.

7. check the version number

Git -- version

If the old version of git exists in the system, after the new git is installed, it is still displayed as the old version after git -- version is used, because I ignores step 6, which is very important!
