[root@oradb bin]# tar zxvf mariadb-10.3.18-linux-x86_64.tar.gz
[root@oradb bin]# mv mariadb-10.3.18-linux-x86_64 /usr/local/
[root@oradb bin]# cd /usr/local/
[root@oradb local]# mv mariadb-10.3.18-linux-x86_64/ mysql/2.新建mysql用户
groupadd mysql
useradd -g mysql mysql
chown mysql:mysql -R /usr/local/mysql3.新建数据库目录
mkdir -p /u01/data
chown mysql:mysql -R /u01/data4.初始化数据库
scripts/mysql_install_db --user=mysql --datadir=/u01/data5.查看my.cnf执行的顺序.
[root@oradb support-files]# /usr/local/mysql/bin/mysqld --verbose --help |grep -A 1 'Default options'

2019-09-23 15:25:07 0 [Warning] Could not open mysql.plugin table. Some options may be missing from the help text
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf 顺序为/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
也可以用如下命令查找:
[root@oradb support-files]# locate my.cnf
/etc/my.cnf6.修改my.cnf
[root@oradb support-files]# vi /etc/my.cnf
[mysqld]
datadir=/u01/data/
socket=/tmp/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/u01/data/mysqld.log
pid-file=/tmp/mysqld.pid7.生成自启动脚本
[root@oradb mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@oradb mysql]# vi /etc/init.d/mysqld
###修改data目录
datadir=/u01/data
[root@oradb mysql]# chkconfig --add mysqld
[root@oradb mysql]# chkconfig mysqld on错误
[root@oradb mysql]# service mysqld start

8.修改环境变量
[root@oradb data]# vi /etc/profile
export PATH=/usr/local/mysql/bin:$PATH
[root@oradb data]# source /etc/profile9.mysql 安全配置
[root@oradb data]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
##是否设置root用户密码
Set root password? [Y/n] Y
##新的root密码
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
## 是否删除匿名用户
Remove anonymous users? [Y/n] Y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
## 是否禁止root远程登录
Disallow root login remotely? [Y/n] Y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
## 是否删除test数据库
Remove test database and access to it? [Y/n] Y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
## 是否重新加载权限表
Reload privilege tables now? [Y/n] Y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!10.进入mysql
[root@oradb data]# mysql -uroot -predhat
