Ctyun系统 升级OpenSSH 9.3

大家好，欢迎来到IT知识分享网。

1、上传zlib-1.2.12，openssl-1.1.t，openssh-9.3p1压缩文件到服务器

zlib下载地址：

zlib Home Sitehttps://zlib.net/

openssl下载地址：/source/index.htmlhttps://www.openssl.org/source/

openssh下载地址

Index of /pub/OpenBSD/OpenSSH/portable/http://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/

2、解压上传压缩包

[root@localhost ~]# yum -y install tar [root@localhost ~]# tar -zxvf 压缩包

3、创建编译目录

[root@localhost ~]# mkdir -p /usr/local/zlib/ [root@localhost ~]# mkdir -p /usr/local/openssl/ [root@localhost ~]# mkdir -p /usr/local/openssh/

4、卸载openssh

# 备份 [root@localhost ~]# cp /etc/ssh/ssh_config /opt/ [root@localhost ~]# cp /etc/ssh/sshd_config /opt/ # 卸载 [root@localhost ~]# yum remove openssh # 查看是否卸载 [root@localhost ~]# rpm -qa | grep openssh

5、卸载openssl

[root@localhost ~]# rpm -qa | grep openssl openssl-1.1.1f-1.ctl2.x86_64 openssl-pkcs11-0.4.10-1.ctl2.x86_64 openssl-libs-1.1.1f-1.ctl2.x86_64 [root@localhost ~]# yum remove openssl [root@localhost ~]# rpm -qa | grep openssl openssl-libs-1.1.1f-1.ctl2.x86_64

6、安装编译需要用到的依赖包

[root@localhost ~]# yum -y install gcc make perl pam

7、编译安装zlib

# 进入zlib解压目录 # 预编译 [root@localhost ~/zlib-1.2.12]# ./configure --prefix=/usr/local/zlib/ # 编译 [root@localhost ~/zlib-1.2.12]# make && make install # 查看版本 [root@localhost ~/zlib-1.2.12]# ll /usr/local/zlib/lib

8、编译安装openssl

# 进入openssl解压目录 # 预编译 [root@localhost ~/openssl-1.1.1t]# ./config --prefix=/usr/local/openssl/ --openssldir=/usr/local/openssl/ shared # 编译 [root@localhost ~/openssl-1.1.1t]# make && make install # 创建软连接文件 [root@localhost ~/openssl-1.1.1t]# ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl [root@localhost ~/openssl-1.1.1t]# ln -s /usr/local/openssl/include/openssl/ /usr/include/openssl # 不摒弃老版本的情况下，下面几步无需执行 echo "/usr/local/openssl/lib" >> /etc/ld.so.conf ldconfig # 检查版本 [root@localhost ~/openssl-1.1.1t]# openssl version OpenSSL 1.1.1t 7 Feb 2023

9、编译安装openssh

# 进入openssh解压目录 # 预编译 [root@localhost ~/openssh-9.3p1]# ./configure --prefix=/usr/local/openssh/ --sysconfdir=/usr/local/openssh/ssh/ --with-openssl-includes=/usr/local/openssl/include/ --with-ssl-dir=/usr/local/openssl/ --with-zlib=/usr/local/zlib/ --with-md5-passwords --without-openssl-header-check # 编译 [root@localhost ~/openssh-9.3p1]# make -j 4 && make install # 创建软连接 [root@localhost ~/openssh-9.3p1]# ln -s /usr/local/openssh/sbin/sshd /sbin/sshd [root@localhost ~/openssh-9.3p1]# ln -s /usr/local/openssh/bin/ssh /usr/bin/ssh [root@localhost ~/openssh-9.3p1]# ln -s /usr/local/openssh/bin/scp /usr/bin/scp [root@localhost ~/openssh-9.3p1]# ln -s /usr/local/openssh/bin/sftp /usr/bin/sftp [root@localhost ~/openssh-9.3p1]# ln -s /usr/local/openssh/bin/ssh-add /usr/bin/ssh-add [root@localhost ~/openssh-9.3p1]# ln -s /usr/local/openssh/bin/ssh-keygen /usr/bin/ssh-keygen [root@localhost ~/openssh-9.3p1]# ln -s /usr/local/openssh/bin/ssh-keyscan /usr/bin/ssh-keyscan # 配置启动脚本，并设置开机自启动 [root@localhost ~/openssh-9.3p1]# cp -rf /root/openssh-9.3p1/contrib/redhat/sshd.init /etc/init.d/sshd [root@localhost ~/openssh-9.3p1]# cp -rf /root/openssh-9.3p1/contrib/redhat/sshd.pam /etc/pam.d/sshd.pam [root@localhost ~/openssh-9.3p1]# chkconfig --add sshd [root@localhost ~/openssh-9.3p1]# chkconfig sshd on # 修改配置文件 [root@localhost ~/openssh-9.3p1]# cp -rf /usr/local/openssh/ssh/* /etc/ssh/ # 查看版本 [root@localhost ~/openssh-9.3p1]# ssh -V OpenSSH_9.3p1, OpenSSL 1.1.1t 31 Mar 2020
