1. Unzip the file
[root@localhost software]# tar -xzvf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
2. Modify the file
[root@localhost software]# mv mysql-5.7.19-linux-glibc2.12-x86_64 mysql
3. Check whether the library file has been deleted, and if so, delete it (it comes with the linux system)
[root@localhost mysql]# rpm -qa | grep mysql
删除
[root@localhost mysql]# rm -e –-nodeps mysql-libs-5.1.52.x86_64
4. Check whether the mysql group and user exist, if not created:
5. Add the data directory under mysql
[root@localhost mysql]# mkdir data
6. Change the combined user of all directories and folders in the mysql directory
[root@localhost /]# cd /usr/local/
[root@localhost local]# chown -R mysql mysql/
[root@localhost local]# chgrp -R mysql mysql/
[root@localhost local]# cd mysql/
[root@localhost mysql]# ls -l
