Initialize MySQL

Cp/root/tools/support-files/mysql.server/etc/init.d/mysqld
Chown–r Mysql.mysql/app/mysql_5.7.21/data
chmod +x/etc/init.d/mysqld
chmod 1777/tmp
Echo ' Export path=/app/mysql-5.7.21/bin: $PATH ' >>/etc/profile
Source/etc/profile
/app/mysql/bin/mysqld--initialize--user=mysql--basedir=/app/mysql-5.7.21--datadir=/app/mysql-5.7.21/data
Note: Initialization completion generates root password, copy, easy login to MySQL reset password

Report warning after initialization is complete
2018-06-17t10:53:58.352241z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. --explicit_defaults_for_timestamp server option (see documentation for more details).

Solve:
Add a line under [Mysqld] in the/etc/my.cnf file Explicit_defaults_for_timestamp = True

Start MySQL Start
/etc/init.d/mysqld start

But it was an error,
It's an error.
An error.
[[email protected] support-files]#/etc/init.d/mysqld start
Starting mysql.2018-06-17t11:08:05.949747z Mysqld_safe Error:log-error set to '/var/log/mariadb/mariadb.log ', however File don ' t exists. Create writable for user ' MySQL '.
error! The server quit without updating PID file (/var/lib/mysql/ecs-adfa.novalocal.pid).

Also saw a few netizens article, some said is deleted my.cnf can start, but, production environment needs to add or modify MySQL configuration file, delete must be not feasible, oneself also did not try to be possible no.

Your own solution:
Manually create a log file and authorize it to MySQL
Mkdir-p/var/log/mariadb
Touch/var/log/mariadb/mariadb.log
Chown-r Mysql.mysql/var/log/mariadb/mariadb.log

Start MySQL again, and error (tried several times, the middle of missing some error messages)
MYSQL Server Startup error ' the server quit without updating PID file '

Solve
Modify the path of the DataDir and sock of the default [mysqld] in MY.CNF
Switch
[Mysqld]
Datadir=/app/mysql-5.7.21/data
Socket=/tmp/mysql.sock

Start MySQL again
[[email protected] support-files]#/etc/init.d/mysqld start
Starting MySQL. success!

However, when mysql-uroot-p log in to MySQL, the error
Said to be unable to find sock (error was not recorded at the time)

Solve:
Add path to Sock
Modify/ETC/MY.CNF.D/MYSQL-CLIENTS.CNF
[MySQL]
Socket=/tmp/mysql.sock

At this point, you can log in, remember to change the password after login, even if you do not modify, MySQL will remind you to modify.

First of all, this is probably recorded, later encountered in the revision.
