拿到CentOS后第一步

参考 http://elrepo.org/tiki/tiki-index.php CentOS 6 $ rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm

$ yum -y update #This will update installed software on CentOS to the latest versions
$ yum -y groupinstall 'Development Tools'
$ yum install man #用于查看各种软件的使用手册
$ yum info man #查看man这软件的说明

rpmforge的源更牛, 如果elrepo的源找不到, 就用rpmforge的源

$ wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
$ rpm -Uvh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

###

$ su -c 'yum provides javac' #查看哪个包提供javac
$ vi /etc/sysconfig/i18n #Change language
$ cat /etc/redhat-release #See Version

修改语言

$ echo $LANG
$ vi /etc/sysconfig/i18n #修改为：LANG="en_US.UTF-8"
$ source /etc/sysconfig/i18n #reload

修改主机名

HOSTNAME=localhost.localdomain

yum install search ngrep没有找到相关可安装包

$ sudo yum install epel-release #参考自 http://www.rackspace.com/knowledge_center/article/install-epel-and-additional-repositories-on-centos-and-red-hat
$ sudo yum upgrade ca-certificates --disablerepo=epel #参考自 http://serverfault.com/questions/637549/epel-repo-for-centos-6-causing-error

make报错

make[1]: g++: Command not found

$ yum groupinstall 'Development Tools'

安装git报错

$ yum update
$ yum install git
报错：No package git available.
解决见： http://blog.csdn.net/laiahu/article/details/7516939
git clone时报错： Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
fatal: Could not read from remote repository.
可能是因为 公钥没有上传到gitlab上。解决见： https://help.github.com/articles/generating-ssh-keys/#platform-linux
还是不行的话解决见： http://stackoverflow.com/questions/21518074/permission-denied-publickey-gssapi-keyex-gssapi-with-mic-on-openshift
这时就要安装ruby了，因为rhc是要用rubygems的。见：https://rvm.io/
Remove the keys: $ rhc sshkey-remove 
https://developers.openshift.com/en/getting-started-rhel-centos.html#client-tools
$ gem install rhc   
这时你要在openshift.com注册了，不过reCAPTCHA是google提供的，要翻墙才行。可以用海bei的VPN。
然后 https://help.github.com/articles/generating-ssh-keys/#platform-linux
http://docs.openshift.com/online/user_guide/ssh_keys.html#tutorial-creating-and-uploading-ssh-keys
$ rhc sshkey add mysshkey ~/.ssh/id_rsa.pub

RPM and yum

rpm -qa | grep postgresql14-devel # To check if a package is installed.
