三种安装方式

 

 

 tar -xf  mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz
[root@sc-mysql opt]# tar -xf  mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz
[root@sc-mysql opt]# ls
apache-zookeeper-3.6.3-bin         kafka_2.12-2.8.1.tgz
apache-zookeeper-3.6.3-bin.tar.gz  mysql-5.7.37-linux-glibc2.12-x86_64
kafka_2.12-2.8.1                   mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz

 上面是解压压缩包
