Error Resolution:

1,

[[email protected] mysql-5.7.13] #./bin/mysql_install_db--user=mysql

2016-06-26 02:47:09 [WARNING] mysql_install_db is deprecated. Consider switching to mysqld--initialize

2016-06-26 02:47:09 [ERROR] The data directory needs to be specified.


WORKAROUND: You need to create a new data directory, specify the installation directory (you need to specify the default path when you are not in the default directory:/usr/local/mysql, and you need to specify./support-files/ Basedir and DataDir in Mysql.server are the corresponding paths).

[[email protected] mysql-5.7.13] #./bin/mysql_install_db--user=mysql--basedir=/usr/local/mysql-5.7.13/--datadir=/usr/local/mysql-5.7.13/ data/

2016-06-26 02:48:47 [WARNING] mysql_install_db is deprecated. Consider switching to mysqld--initialize

2016-06-26 02:49:19 [WARNING] The bootstrap log isn ' t empty:

2016-06-26 02:49:19 [WARNING] 2016-06-26t09:48:50.798592z 0 [WARNING]--bootstrap is deprecated. Please consider using--initialize instead

2016-06-26t09:48:50.898732z 0 [Warning] Changed limits:max_open_files:1024 (requested 5000)

2016-06-26t09:48:50.898778z 0 [Warning] Changed limits:table_open_cache:431 (requested 2000)

A custom path is not specified in Mysql.server because of an escalation error.


2, starting the MySQL service is unsuccessful.

[[Email protected] ~] #/etc/init.d/mysqld Start

/etc/init.d/mysqld:line 256:my_print_defaults:command not found

Starting MySQL error! Couldn ' t find MySQL server (/usr/local/mysql/bin/mysqld_safe)

Resolution: The original default path is the/usr/local/mysql directory, where the directory is/usr/local/mysql-5.7.13.

Change the mysql-5.7.13 to MySQL and restart, and find the following error:

error! MySQL server PID file could not being found!

Confirm that the current directory owner is root and change to MySQL:

[[email protected] local] # chown-r Mysql:mysql mysql/

[[email protected] local] #/etc/init.d/mysqld Restart

error! MySQL server PID file could not being found!

Starting MySQL ..... success!


3, the login was unsuccessful because the service did not start.

[[email protected] mysql-5.7.13] # Cat/root/.mysql_secret

# Password set for user ' [e-mail protected] ' at 2016-06-26 02:48:47

: Jidfmi%5kak

[[email protected] mysql-5.7.13] #./bin/mysql-uroot-p

Enter Password:

ERROR 2002 (HY000): Can ' t connect to local MySQL server through socket '/tmp/mysql.sock ' (2)

Workaround: This problem disappears after the 2nd problem is resolved (the MYSQLD service needs to be started).
