centos7安装mariadb出现依赖问题的解决

 

今天我想安装mariadb-server服务，但是突然间报了这么多错误。

Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).
The program yum-complete-transaction is found in the yum-utils package.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

报了这么多错误，我也是花费了大量的心思去解决，可是总是不尽人意，还是报错误，突然见我又仔细的查看一下错误的原因，细心一点才发现自己解决错了放心。

大家来看上面的青色背景的话，猛地一看这么多，脑子都懵逼了。不过想要解决，我们得自己慢慢研究才行

仔细一看其实最主要的愿意是青色背景的第一行，也就是这个

Error: MariaDB-compat conflicts with 1:mariadb-libs-5.5.64-1.el7.x86_64

说白了就是MariaDB-compat这个包和mariadb-libs这个包发生了冲突，既然发生了冲突，我们就要看看安装这个mariadb-server的时候，它需要的是这两个冲突包其中的哪个包，仔细一看

 

 不难发现，mariab-server需要安装的是mariadb-libs这个包，但是安装这个包的时候发现“Installed”，也就是后面的MariaDB-compat这个包已经存在系统上面了，那么解决的方法就是把MariaDB-compat给卸载了。

现在我搜索一下

[root@chaofeng ~]# rpm -qa | grep MariaDB
MariaDB-common-10.2.31-1.el7.centos.x86_64
MariaDB-compat-10.2.31-1.el7.centos.x86_64

发现有两个包，那我干脆两个都直接卸载算了。我使用这种方法居然还不行

[root@chaofeng ~]# rpm -qa | grep MariaDB | xargs rpm -e
error: Failed dependencies:
    libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-7.el7.x86_64

    libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) zabbix-proxy-mysql-4.4.7-1.el7.x86_64

原来是卸载的包之间也是有依赖的，所以卸载的时候有一个先后顺序，

[root@chaofeng ~]# rpm -e MariaDB-compat-10.2.31-1.el7.centos.x86_64 --force
rpm: only installation and upgrading may be forced

接着卸载另一个

[root@chaofeng ~]# rpm -e MariaDB-common-10.2.31-1.el7.centos.x86_64

两个都卸载完毕了。这样子就清楚了

终于可以安装mariadb-server了
