1、安装MariaDB
dnf -y install mariadb-server
2、修改配置
# vim /etc/my.cnf [client] port = 3306 socket = /var/lib/mysql/mysql.sock default-character-set = utf8mb4 [mysqld] port = 3306 socket = /var/lib/mysql/mysql.sock datadir = /var/lib/mysql pid-file = /var/lib/mysql/mysql.pid user = mysql bind-address = 0.0.0.0 server-id = 1 init-connect = 'SET NAMES utf8mb4' character-set-server = utf8mb4 skip-name-resolve #skip-networking back_log = 300 max_connections = 5246 max_connect_errors = 6000 open_files_limit = 65535 table_open_cache = 1024 max_allowed_packet = 500M binlog_cache_size = 1M max_heap_table_size = 8M tmp_table_size = 128M read_buffer_size = 2M read_rnd_buffer_size = 8M sort_buffer_size = 8M join_buffer_size = 8M key_buffer_size = 256M thread_cache_size = 64 query_cache_type = 1 query_cache_size = 64M query_cache_limit = 2M ft_min_word_len = 4 log_bin = mysql-bin binlog_format = row expire_logs_days = 7 log_error = /var/lib/mysql/mysql-error.log slow_query_log = 1 long_query_time = 1 slow_query_log_file = /var/lib/mysql/mysql-slow.log performance_schema = 0 lower_case_table_names = 1 skip-external-locking default_storage_engine = InnoDB innodb_file_per_table = 1 innodb_open_files = 500 innodb_buffer_pool_size = 1024M innodb_write_io_threads = 4 innodb_read_io_threads = 4 innodb_purge_threads = 1 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 2M innodb_log_file_size = 32M innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 bulk_insert_buffer_size = 8M myisam_sort_buffer_size = 64M myisam_max_sort_file_size = 10G interactive_timeout = 28800 wait_timeout = 28800 binlog_annotate_row_events = 1 log_bin_trust_function_creators = 1 sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION #sql_mode = NO_AUTO_VALUE_ON_ZERO [mysqldump] quick max_allowed_packet = 500M [myisamchk] key_buffer_size = 256M sort_buffer_size = 8M read_buffer = 4M write_buffer = 4M
3、启动服务
systemctl enable --now mariadb
4、安全配置
# 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
haven't set the root password yet, you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.
You already have your root account protected, so you can safely answer 'n'.
Switch to unix_socket authentication [Y/n] n
... skipping.
You already have your root account protected, so you can safely answer 'n'.
Change the root password? [Y/n] y
New password: #输入密码
Re-enter new password: #输入密码
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.
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.
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.
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.
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!
