一、下载MariaDB
wget https://downloads.mariadb.com/MariaDB/mariadb-10.3.7/bintar-linux-glibc_214-x86_64/mariadb-10.3.7-linux-glibc_214-x86_64.tar.gz
二、安装MariaDB
- 准备
(1)解压tar.gz文件
tar -zxvf mariadb-10.3.7-linux-glibc_214-x86_64.tar.gz
(2)将解压后的文件夹移动至 /usr/local 文件夹下
mv mariadb-10.3.7-linux-glibc_214-x86_64 /usr/local
(3)切换工作目录至 /usr/local
cd /usr/local
(4)创建文件链接mysql
ln -s mariadb-10.3.7-linux-glibc_214-x86_64 mysql
(5)创建mysql用户组及用户
groupadd mysql
useradd -g mysql mysql
创建数据目录
mkdir /home/mysql/data
- 安装配置
(1)执行配置脚本
cd mysql
./scripts/mysql_install_db --user=mysql --datadir=/home/mysql/data
(2)更改文件及文件夹权限
chown -R root:mysql .
chown -R mysql:mysql data
修改/etc/my.cnf中的配置
datadir = /app/dbdata
innodb_file_per_table = on
skip_name_resolve = on
查看my.cnf下面几个文件路径,创建它并将权限赋给mysql用户与用户组
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
mkdir /var/log/mariadb
mkdir /var/run/mariadb
touch /var/log/mariadb/mariadb.log
touch /var/run/mariadb/mariadb.pid
chown -R mysql:mysql /var/run/mariadb
chown -R mysql:mysql /var/log/mariadb
3. 启动数据库
./bin/mysqld_safe --user=mysql --datadir=/home/mysql/data &
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
-
设置数据库root用户密码
(1)设置root用户密码
./bin/mysqladmin -u root password ‘123456’
(2)查看主机名
[root@ecs-test1 mysql]# hostname
ecs-test1.novalocal
(3)设置连接到本主机的root用户密码
./bin/mysqladmin -u root -h localhost.localdomain password ‘123456’ -
关闭数据库
[root@ecs-test1 mysql]# ./bin/mysqladmin -uroot -p shutdown
Enter password:
[1]+ Done ./bin/mysqld_safe --user=mysql
四、数据库连接、查询
-
连接与登录
[root@ecs-test1 mysql]# ./bin/mysql -uroot -p
Enter password: -
查询
MariaDB [(none)]> show databases;
MariaDB [(none)]> use mysql;
MariaDB [mysql]> desc user;
MariaDB [mysql]> select host,user,password from user;
