Centos7升級OpenSSH
1、下載相關依賴包
# yum install -y gcc openssl-devel pam-devel rpm-build
2、 下載安裝包
wget http://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-7.9p1.tar.gz
3、解除安裝原Openssh
[[email protected] ~]# rpm -qa |grep openssh
openssh-7.4p1-16.el7.x86_64
openssh-clients-7.4p1-16.el7.x86_64
openssh-server-7.4p1-16.el7.x86_64
[[email protected] ~]# for i in $(rpm -qa |grep openssh);do rpm -e $i --nodeps;done
4、解壓openssh安裝包
tar -xvf openssh-7.9p1.tar.gz
[[email protected] openssh-7.9p1]# cd openssh-7.9p1
5、編譯安裝
[[email protected] openssh-7.9p1]# ./configure --prefix=/usr --sysconfdir=/etc/ssh --with-md5-passwords--with-pam --with-tcp-wrappers --with-ssl-dir=/usr/local/ssl --without-hardening
[
[[email protected] openssh-7.9p1]# make && make install
6、安裝完成，執行配置
[[email protected] openssh-7.8p1]# cp contrib/redhat/sshd.init /etc/init.d/sshd [[email protected] openssh-7.8p1]# chkconfig --add sshd [[email protected] openssh-7.8p1]# chkconfig sshd on [
[[email protected] openssh-7.8p1]# systemctl restart sshd
7、檢視版本
[[email protected] openssh-7.9p1]# systemctl status sshd
