centos7 openssh升级到9.3.p1

配置openssh目录
cp /etc/ssh/sshd_config  /etc/ssh/sshd_config.bak
cp /etc/pam.d/sshd /etc/pam.d/sshd.bak
mkdir -p /root/openssh
cd /root/openssh


上传已经制作好的openssh包
openssh-9.3p1-1.el7.x86_64.rpm
openssh-clients-9.3p1-1.el7.x86_64.rpm 
openssh-server-9.3p1-1.el7.x86_64.rpm

rpm -Uvh /root/openssh/*.rpm --force --nodeps --nosignature

修改ssh目录权限
chmod 600 /etc/ssh/ssh_host_rsa_key
chmod 600 /etc/ssh/ssh_host_ecdsa_key
chmod 600 /etc/ssh/ssh_host_ed25519_key

移除sshd_config配置
mv /etc/ssh/sshd_config /etc/ssh/sshd_config.bak1
恢复原先的ssh配置
mv /etc/ssh/sshd_config.bak /etc/ssh/sshd_config


修改sshd_config参数，否则root无法登录
sed -i -e "s/#PasswordAuthentication yes/PasswordAuthentication yes/g" /etc/ssh/sshd_config
sed -i -e "s/#PermitEmptyPasswords no/PermitEmptyPasswords no/g" /etc/ssh/sshd_config
sed -i -e "s/#PermitRootLogin prohibit-password/PermitRootLogin yes/g" /etc/ssh/sshd_config
sed -i -e "s/#PermitRootLogin yes/PermitRootLogin yes/g" /etc/ssh/sshd_config



修改/etc/pam.d/sshd的配置 
cat > /etc/pam.d/sshd <<EOF
#%PAM-1.0 
auth required pam_sepermit.so 
auth include password-auth 
account required pam_nologin.so 
account include password-auth 
password include password-auth 
# pam_selinux.so close should be the first session rule 
session required pam_selinux.so close 
session required pam_loginuid.so 
# pam_selinux.so open should only be followed by sessions to be executed in the user context 
session required pam_selinux.so open env_params 
session optional pam_keyinit.so force revoke 
session include password-auth
EOF
