MariaBD安装配置
官方地址:https://mariadb.com/docs/server/deploy/topologies/single-node/community-server-10-5/
YUM安装:
1、下载用到 wget 工具;
yum install wget
2、下载 MariaDB repo 的安装文件;默认下载到当前文件夹
wget https://r.mariadb.com/downloads/mariadb_repo_setup
3、特征码校验(可跳过该步骤);
echo "ad125f01bada12a1ba2f9986a21c59d2cccbe8d584e7f55079ecbeb7f43a4da4 mariadb_repo_setup" | sha256sum -c -
4、安装 MariaDB repo;
chmod +x mariadb_repo_setup && ./mariadb_repo_setup --mariadb-server-version="mariadb-10.5"
5、安装server以及相关的工具包;
yum install MariaDB-server MariaDB-backup
安装完成。
启动:
systemctl start mysqld
设置开机自启:
systemctl enable mysqld
执行安全初始化程序:
mysql_secure_installation
配置说明:
/etc/my.cnf 用来声明包含 /etc/my.cnf.d/ 下的所有配置文件:
/etc/my.cnf.d/client.cnf
/etc/my.cnf.d/mysql-clients.cnf
/etc/my.cnf.d/server.cnf
server.cnf:
[galera]
# 跳过主机名解析,避免对主机名解析造成响应慢
skip_name_resolve=on
innodb_file_per_table = on
# 修改数据的存储目录
datadir = /var/mysql_data
调整数据的存放目录:
配置文件:server.cnf
参数:datadir = /var/mysql_data
注意事项: /var/mysql_data 必须事先存在,将 /var/lib/mysql/ 下的所有文件都必须拷贝到 /var/mysql_data 中,同时注意文件的权限,建议使用 cp -ar 进行拷贝,将 /var/mysql_data 的属主和属组改为 mysql;保留 /var/lib/mysql/ mariadb在运行的时候会用到该目录,尽量不要删除;
登录:
MariaDB在安装之后,系统默认创建 root@localhost 和 mysql@localhost 两个用户,是不需要密码便可登录的。
设置密码:
MariaDB [(none)]> use mysql; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed MariaDB [mysql]> SELECT PASSWORD('root'); +-------------------------------------------+ | PASSWORD('root') | +-------------------------------------------+ | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | +-------------------------------------------+ 1 row in set (0.000 sec) MariaDB [mysql]> ALTER USER root@localhost IDENTIFIED VIA mysql_native_password USING '*81F5E21E35407D884A6CD4A731AEBFB6AF209E1B'; Query OK, 0 rows affected (0.000 sec) MariaDB [mysql]> flush privileges; Query OK, 0 rows affected (0.001 sec)
