yum安装软件(官网很慢)
yum install mariadb 发现版本如下,版本特别低,且安装包特别小, mariadb x86_64 1:5.5.60-1.el7_5 base 8.9 M 2.我们可以配置mariadb官方的yum源(官方的mariadb包一定是最新的,最好的,功能最全的,但是下载速度可能很慢) 配置官方mariadb的yum源步骤 1.新建一个yum源仓库 touch /etc/yum.repos.d/Mariadb.repo 2.在这个yum源仓库文件中,添加仓库url地址 [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.1/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1 3.一条命令安装mariadb yum install MariaDB-server MariaDB-client -y
由于官方的下载网速忒慢了,我们学习使用阿里云的mariadb数据库!!
重命名这个Mariadb.repo文件
mv /etc/yum.repos.d/Mariadb.repo /etc/yum.repos.d/Mariadb.repo.bak
使用阿里云的mariadb
yum install mariadb-server mariadb -y
启动mariadb数据库
systemctl start/stop/status/restart mariadb
初始化数据库
mysql_secure_installation
登录数据库
mysql -uroot -p
设置mariadb数据库支持中文
vim /etc/my.cnf
[mysqld] character-set-server=utf8 collation-server=utf8_general_ci log-error=/var/log/mysqld.log datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # Settings user and group are ignored when systemd is used. # If you need to run mysqld under a different user or group, # customize your systemd unit file for mariadb according to the # instructions in http://fedoraproject.org/wiki/Systemd [client] default-character-set=utf8 [mysql] default-character-set=utf8 [mysqld_safe] log-error=/var/log/mariadb/mariadb.log pid-file=/var/run/mariadb/mariadb.pid # # include all files from the config directory # !includedir /etc/my.cnf.d
重启数据库服务
systemctl restart mariadb
登录新的数据库,查看中文编码设置
MariaDB [(none)]> s
10.查看数据库的编码设置,以及表的设置 show create database qishi1; show create table shenqu;
