#安装相关的组件

Yum-y install gcc openssl-devel pam-devel rpm-build

Second, the following start to upgrade SSH, here I wrote two ways to upgrade

1. Compile and install OpenSSH

# tar xzvf openssh-6.2p1.tar.gz# cd openssh-6.2p1#./configure--prefix=/usr--sysconfdir=/etc/ssh

Download is the source package to compile, note my compilation path, I am talking about OpenSSH installed in the original path, so after the installation after the completion of the need not in the Copy sshd service to/etc/init.d/! , you can customize the installation path according to the actual situation.

makemv/etc/ssh/*/etc/sshbak/because I made the installation in the original path, so I moved the old configuration file position, or make install will error! Make install

/etc/init.d/sshd restart

Pay attention to security here, if you compile an error before, and also force installation, sshd service may not get up

Chkconfig--add sshd chkconfig sshd on

After you restart the SSH service, review the version

2, RPM Package installation

Compile the source program for RPM installation package

Install the compiled RPM package

cd/usr/src/redhat/rpms/' uname-i ' RPM-UVH openssh*rpm
