centos 彻底卸载软件包（含依赖）并解决安装冲突包问题

1、查看yum操作事务

[root@localhost ~]# yum history list 或 yum history
Loading "fastestmirror" plugin
Config time: 0.007
Yum version: 3.4.3
ID     | Login user               | Date and time    | Action(s)      | Altered
-------------------------------------------------------------------------------
     3 | root <root>              | 2022-05-20 15:38 | Install        |   12 EE
     2 | root <root>              | 2022-05-20 10:38 | I, U           |    8   
     1 | System <unset>           | 2022-05-20 10:05 | Install        |  311   

2、查看某个事务的详细信息

[root@localhost ~]# yum history info 3
Loaded plugins: fastestmirror
Transaction ID : 3
Begin time     : Mon Jan 10 15:38:41 2022
Begin rpmdb    : 318:0a512f196782814fe726bc61f44b5332aac74b38
End time       :            15:38:44 2022 (3 seconds)
End rpmdb      : 330:d9fb4e7bea655b40bcabffd6eb2a8a2f81110793
User           : root <root>
Return-Code    : Success
Command Line   : install zabbix-server-mysql zabbix-agent
Transaction performed with:
    Installed     rpm-4.11.3-32.el7.x86_64                      @anaconda
    Installed     yum-3.4.3-158.el7.centos.noarch               @anaconda
    Installed     yum-plugin-fastestmirror-1.1.31-45.el7.noarch @anaconda
Packages Altered:
    Dep-Install OpenIPMI-libs-2.0.23-2.el7.x86_64          @centos7
    Dep-Install OpenIPMI-modalias-2.0.23-2.el7.x86_64      @centos7
    Dep-Install fping-3.10-4.el7.x86_64                    @epel

Scriptlet output:
   1 sed: can't read /etc/sysconfig/ipmi: No such file or directory
history info

3、卸载安装包（也就是回滚）

[root@localhost ~]# yum history undo 3
......
Removed:
  OpenIPMI-libs.x86_64 0:2.0.23-2.el7           OpenIPMI-modalias.x86_64 0:2.0.23-2.el7             fping.x86_64 0:3.10-4.el7              libevent.x86_64 0:2.0.21-4.el7               net-snmp-libs.x86_64 1:5.7.2-32.el7                 
  traceroute.x86_64 3:2.0.22-2.el7              unixODBC.x86_64 0:2.3.1-11.el7                      zabbix50.x86_64 0:5.0.18-1.el7         zabbix50-agent.x86_64 0:5.0.18-1.el7         zabbix50-dbfiles-mysql.noarch 0:5.0.18-1.el7        
  zabbix50-server.noarch 0:5.0.18-1.el7         zabbix50-server-mysql.x86_64 0:5.0.18-1.el7  

4、查看yum history help信息

[root@localhost ~]# yum history help
Loaded plugins: fastestmirror
Invalid history sub-command, use: list, info, summary, repeat, redo, undo, new, rollback, addon, addon-info, stats, statistics, sync, synchronizepkg, pkgs, pkg-list, pkgs-list, package, package-list, packages, packages-list, pkg-info, pkgs-info, package-info, packages-info.

5、当安装时提示有冲突时

Error: Package: glibc-devel-2.17-317.el7.x86_64 (c7-media)
           Requires: glibc-headers = 2.17-317.el7
           Installing: glibc-headers-2.17-260.el7.x86_64 (c7-media)
               glibc-headers = 2.17-260.el7
Error: Package: glibc-devel-2.17-317.el7.x86_64 (c7-media)
           Requires: glibc-headers = 2.17-317.el7
           Available: glibc-headers-2.17-260.el7.x86_64 (c7-media)
               glibc-headers = 2.17-260.el7
Error: Package: glibc-devel-2.17-317.el7.x86_64 (c7-media)
           Requires: glibc = 2.17-317.el7
           Installed: glibc-2.17-260.el7.x86_64 (@anaconda)
               glibc = 2.17-260.el7
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

安装包冲突了，卸载掉（移除）已经安装的glibc-devel-2.17-317.el7.x86_64.rpm包即可
[root@localhost ~]#yum remove -y glibc-devel-2.17-317.el7.x86_64
