这个错误提示是因为 conntrack-tools-1.4.4-7.el7.x86_64 这个软件包所依赖的一些库文件没有安装或者版本过低。你可以尝试用以下命令安装这些依赖库：

sudo yum install libnetfilter_cthelper libnetfilter_cttimeout libnetfilter_queue

如果还有其他依赖问题，可以继续按照错误提示来安装相应的依赖库。如果还无法解决问题，可以尝试升级系统或者找到更高版本的软件包来安装。

[dzzzapp@gxzc-dzzz-0007 ~]$ sudo rpm -Uvh mysql-community-libs-8.0.33-1.el7.x86_64.rpm warning: mysql-community-libs-8.0.33-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY 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) postfix-2:2.10.1-7.el7.x86_64

根据你提供的信息，安装mysql-community-libs-8.0.33-1.el7.x86_64.rpm时出现了依赖问题，提示缺少libmysqlclient.so.18()(64bit)和libmysqlclient.so.18(libmysqlclient_18)(64bit)。同时，提示已安装的postfix-2:2.10.1-7.el7.x86_64也需要这些依赖。

你需要先安装缺失的依赖，可以使用以下命令安装：

sudo yum install mysql-community-libs-compat

安装完毕后，再次尝试安装mysql-community-libs-8.0.33-1.el7.x86_64.rpm即可。
