To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

./bin/mysqladmin -u root password ‘new-password’
./bin/mysqladmin -u root -h localhost.localdomain password ‘new-password’

Alternatively you can run:

./bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

The latest information about MySQL is available on the web at

http://www.mysql.com

Support MySQL by buying support/licenses at http://shop.mysql.com

New default config file was created as ./my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
–defaults-file argument to mysqld_safe when starting the server

复制mysql.server至启动目录

[root@localhost mysql]#cp support-files/mysql.server /etc/init.d/mysql.server

[root@localhost mysql]# chown -R mysql:mysql /var/log/

[root@localhost mysql]# mkdir -p /var/log/mariadb
[root@localhost mysql]# touch /var/log/mariadb/mariadb.log

以安全模式启动mysql并修改mysql密码

[root@localhost mysql]#bin/mysqld_safe –user=mysql &
[root@localhost mysql]#./bin/mysqladmin -u root password ‘123456’

配置mysql允许远程访问

[root@localhost mysql]#sql>mysql -uroot -p
[root@localhost mysql]#sql> use mysql;
GRANT ALL PRIVILEGES ON *.* TO ‘root’@’%’ IDENTIFIED BY  ‘123456’  WITH GRANT OPTION;
flush privileges;

regist service

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

停止安全模式下的mysql的进程命令

[root@localhost mysql]#mysqladmin -uroot -p shutdown

start with shell:
配置开机启动

[root@localhost mysql]# chmod 755 /etc/init.d/mysqld
[root@localhost mysql]#chkconfig –list mysqld
[root@localhost mysql]#chkconfig –add mysqld
[root@localhost mysql]#chkconfig mysqld on

注意防火墙是否开启

[root@localhost bin]# systemctl status firewalld
[root@localhost bin]# systemctl disable firewalld

Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@localhost bin]# systemctl stop firewalld
[root@localhost bin]# systemctl status firewalld

配置mysql全局的编码方式

[mysql]
default-character-set=utf8

[mysqld]
character_set_server=utf8
