本文带领大家升级最新版本的openssh6.1哦。
首先,安装zlib
下载地址:http://www.jb200.com/down/56.html
安装openssl
下载最新包:http://www.openssl.org/source/openssl-1.0.1c.tar.gz
tar zxvf openssl-1.0.1c.tar.gz
cd openssl-1.01c
./config shared zlib --prefix=/usr/local/openssl
make && make install
whereis openssl
cd /usr/bin/
mv openssl openssl.bak
ln -s /usr/local/openssl/bin/openssl .
cd /usr/include/
mv openssl openssl.bak
ln -s /usr/local/openssl/include/openssl .
验证:
安装openssh
下载最新安装包:http://openbsd.org.ar/pub/OpenBSD/OpenSSH/portable/openssh-6.1p1.tar.gz
tar zxvf openssh-6.1p1.tar.gz
cd openssl-6.1p1
./configure --prefix=/usr//local/openssh --sysconfdir=/usr/local/openssh/etc/ssh --with-pam --with-zlib=/usr/local/zlib/ --with-ssl-dir=/usr/local/openssl/ --with-md5-passwords-mandir=/usr/share/man/
make && make install
若提示:configure: error: PAM headers not found
安装 pam* pam-devel 是关键
yum -y install pam*
查看sshd运行状态:
netstat -anptul | grep :22
停掉服务,取消开机启动:
service sshd stop
chkconfig sshd off
设置环境变量:
echo "export
PATH=/usr/local/openssh/bin:$JAVA_HOME/bin:$PATH " >>/etc/profile
使其生效:
source /etc/profile
设置sshd开机启动:
启动sshd
/usr/local/opoenssh/sbin/sshd
没有错误提示
查看进程监听状态
[root@localhost ~]# lsof -i:22
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
sshd 2686 root 3u IPv6 11222 TCP *:ssh(LISTEN)
sshd 2686 root 4u IPv4 11230 TCP *:ssh(LISTEN)
说明服务已经正常启动。
查看ssh版本:
[root@localhost ~]# ssh -v
OpenSSH_6.1p1, OpenSSL 1.0.1c 10 May 2012

或者:
[root@localhost ~]# telnet localhost 22
