一、由于环境变量没有添加、添加即可
查看mysqldump位置
[root@VM-20-10-centos data]# sudo find / -name mysqldump
/usr/local/mysql-5.7.44/bin/mysqldump
vim /etc/profile
export MYSQL_HOME=/usr/local/mysql-5.7.44
export PATH=.:${MYSQL_HOME}/bin:$PATH
source /etc/profile二、查看到地址添加一个软连接即可
ln -s /usr/local/mysql-5.7.44/bin/mysqldump /usr/bin
