Go is a quite new programming language. It was developed\u00a0 in 2007 by Robert Griesemer<\/a>, Rob Pike<\/a>, and Ken Thompson<\/a>. Although it’s not as mature as C, Python or Java, it has already gained significant popularity in developers community. For instance, Docker is written in Go. It’s also in active use in Dropbox, Canonical and definitely in Google<\/a>. CoreOS uses Go as well. If you would like to give it a shoot, first thing you need to do is to install it. \u00a0The easiest way to install is to use standard package manager, as apt-get for Ubuntu \/ Debian or yum (Fedora). \u00a0But if you need it on Centos, it’s not that easy. \u00a0Although Go developers provide binary packages, we’d like to install RPM package. It make everything much easier later when you need to update it or uninstall. You can write your own spec file, but it’s much easier to user the SPEC file <\/a>\u00a0prepared by\u00a0Jehiah Czebotar<\/a>. The only thing we need is to modify current version. At the time of writing it’s\u00a0go1.3.3.linux-amd64.tar.gz. We assume you have your environment prepared for RPM building.<\/p>\n

Go to your SPEC directory and download the SPEC file.<\/p>\n

wget https:\/\/gist.githubusercontent.com\/jehiah\/3867005\/raw\/f5190c21a40ffedcbbcd020405c0f50e57287e0e\/go.spec<\/code><\/p>\n

Modify the version to match the current one:<\/p>\n

Source0: go1.3.3.linux-amd64.tar.gz<\/code><\/p>\n

cd to your ~\/SOURCES and download the sources codes:<\/p>\n

wget https:\/\/storage.googleapis.com\/golang\/go1.3.3.linux-amd64.tar.gz<\/code><\/p>\n

We are ready to build Go:<\/p>\n

rpmbuild -bb ~\/rpmbuild\/SPECS\/go.spec<\/code><\/p>\n

Let’s check if everything is ok:<\/p>\n

[root@dev ~]# rpm -ivh --test rpmbuild\/RPMS\/x86_64\/go-devel-go1.3.3-1.x86_64.rpm\nPreparing...                ########################################### [100%]\n[root@dev ~]#\n<\/pre>\n
If it is install Go rpm:<\/p>\n
rpm -ivh rpmbuild\/RPMS\/x86_64\/go-devel-go1.3.3-1.x86_64.rpm<\/code><\/p>\n
Update your bash env variable to make sure it knows where go is:<\/p>\n
[root@dev ~]# bash\n[root@dev ~]# which go\n\/\/usr\/local\/go\/bin\/go\n[root@dev ~]#\n<\/pre>\n
[root@dev ~]# go version\ngo version go1.3.3 linux\/amd64\n[root@dev ~]#\n\n<\/pre>\n
So far so good. Create an example:<\/p>\n
[root@dev ~]# cat hi.go\npackage main\nimport \"fmt\"\nfunc main() {\n    fmt.Println(\"hello world\")\n}\n[root@dev ~]#<\/pre>\n
To build and launch run:<\/p>\n
[root@dev ~]# go run hi.go\nhello world\n[root@dev ~]#<\/pre>\n
Now we can dive in Go world. Good start point can be found at gobyexample.com<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
