Error: transaction check vs depsolve:
(gcc >= 8 with gcc < 9) is needed by annobin-9.72-1.el8_5.2.x86_64
如果遇上需要annobin包报错， 用 rpm 强制安装一下
rpm -ivh --nodeps --force `find /var/cache/dnf -name annobin*`
这几个包也可以删除
dnf -y remove NetworkManager dracut-network python36-rpmconf
centos8的三个包centos-release centos-gpg-keys centos-repos版本会有变动, 操作的时候需要注意选择更新.
也可以不用http://mirror.centos.org/centos/8/BaseOS/x86_64/os/Packages/ ,选用centos vault的库.
总结
在dnf -y --releasever=8 的时候遇上 rpm 包需要的就用rpm -ivh --nodeps --force强制安装， 其他要不就是rpm -e --nodeps强制卸载一下

新装系统的esxi密码正确无法登陆, 在几年前就遇上过用,在shell下操作重置解决的, 但时间太久忘记了, 然后最近又遇上了几次像无头苍蝇一样,特此记录一下.
主要原因是ssh端口被爆破错误次数过多,导致锁死的问题.
新装系统,登陆上管理页面后在“管理”->"高级设置"里面搜索把Security.AccountLockFailures设置成0或者是关闭ssh服务
Security.AccountLockFailures
Security.AccountUnlockTime
或者用PowerCLI进行操作
Set-VMHostAdvancedConfiguration Security.AccountLockFailures -Value 0
Set-VMHostAdvancedConfiguration Security.AccountUnlockTime -Value 0
也可以在设置成ssh key登陆, 对root账户进行重置解决
authorized_keys路径
/etc/ssh/keys-root/authorized_keys
重置命令
pam_tally2 --user root
pam_tally2 --user root --reset
如果新装系统已经被锁死还没设置key登陆, 则需要到ipmi下操作.
在Troubleshooting mode options项目下选择Restart Management Agents进行重置, 之后就可以再用web或者客户端进行登陆设置了.

touch /etc/authbind/byport/179
chmod 755 /etc/authbind/byport/179
在 /etc/init.d/sflow-rt文件内找到START这一行
START='authbind --deep /usr/local/sflow-rt/bin/run-rt'
