[client]
socket = / var / lib / MySQL / Data / mysql.sock

17. Installation mysql
mysqld --user=root --basedir=/usr/local/mysql --datadir=/var/lib/mysql/data --initialize
After a successful installation, you need to pay attention to the last line: # WQ.os6 <wwk to mysql random password?
2019-10-27T01:28:32.711916Z 1 [Note] A temporary password is generated for root@localhost: #WQ.os6?<wwk
18. Start mysql:
service mysql start
19. The configuration environment variable:
vi / etc / profile at the end add: Export the PATH = $ the PATH: / usr / local / MySQL / bin
20. Refresh environment variable file:
