ssh CentOS公升級OpenSSH到最新版本

公升級安裝openssh需要停止服務，適用telnet暫時代替遠端連線，安裝完成後再解除安裝

yum -y install telnet-server* telnet

# vi /etc/xinetd.d/telnet #將其中disable欄位的yes改為no以啟用telnet服務

# mv /etc/securetty /etc/securetty.old #允許root使用者通過telnet登入

# service xinetd start #啟動telnet服務

# chkconfig xinetd on #使telnet服務開機啟動，避免公升級過程中伺服器意外重啟後無法遠端登入系統

yum install gcc pam-devel openssl-devel gcc-c++ make -y

mv /etc/ssh /etc/ssh.old

mv /etc/init.d/sshd /etc/init.d/sshd.old

# rpm -qa | grep openssh openssh-clients-5.3p1-104.el6.x86_64 openssh-server-5.3p1-104.el6.x86_64 openssh-5.3p1-104.el6.x86_64 openssh-askpass-5.3p1-104.el6.x86_64 # rpm -e --nodeps openssh-5.3p1-104.el6.x86_64 # rpm -e --nodeps openssh-server-5.3p1-104.el6.x86_64 # rpm -e --nodeps openssh-clients-5.3p1-104.el6.x86_64 # rpm -e --nodeps openssh-askpass-5.3p1-104.el6.x86_64

# rpm -qa | grep openssh

注意：解除安裝過程中如果出現以下錯誤

# rpm -e --nodeps openssh-server-5.3p1-104.el6.x86_64 error reading information on service sshd: no such file or directory

error: %preun(openssh-server-5.3p1-104.el6.x86_64) scriptlet failed, exit status 1

解決辦法：

#rpm -e --noscripts openssh-server-5.3p1-104.el6.x86_64

# install -v -m700 -d /var/lib/sshd

# chown -v root:sys /var/lib/sshd

get tar -zxf openssh-7.7p1.tar.gz cd openssh-7.7p1 ./configure --prefix=/usr --sysconfdir=/etc/ssh --with-md5-passwords --with-pam --with-ssl --with-zlib --with-openssl-includes=/usr --with-privsep-path=/var/lib/sshd mandir=/usr/share/man/ make &&make

install

# 在openssh編譯目錄執行如下目錄 # echo 'x11forwarding yes' >> /etc/ssh/sshd_config # echo "permitrootlogin yes" >> /etc/ssh/sshd_config #允許root使用者通過ssh登入 # cp -p contrib/redhat/sshd.init /etc/init.d/sshd # chmod +x /etc/init.d/sshd # chkconfig --add sshd # chkconfig sshd on # chkconfig --list sshd

# service sshd restart
