Posted 2021-10-30 xiaofengfree

1）增加mariaDB的yum源

1 2 3 4 5 6 7 8 9

[[email protected] ~]# cd /etc/yum.repos.d/ [[email protected] yum.repos.d]# cp CentOS-Base.repo CentOS-Base.repo.bak [[email protected] yum.repos.d]# vim CentOS-Base.repo ...... [mariadb]    name = MariaDB baseurl = http://yum.mariadb.org/10.3.5/centos6-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB   gpgcheck=1

2）yum安装MariaDB

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

[[email protected] yum.repos.d]# yum install -y MariaDB-server MariaDB MariaDB-client   安装好后，启动服务 [[email protected] yum.repos.d]# /etc/init.d/mysql start [[email protected] yum.repos.d]# ps -ef|grep mysql [[email protected] yum.repos.d]# lsof -i:3306   设置开机启动 [[email protected] yum.repos.d]# chkconfig mysql on   [[email protected] yum.repos.d]# mysql Welcome to the MariaDB monitor.  Commands end with ; or \g. Your MariaDB connection id is 9 Server version: 10.3.5-MariaDB MariaDB Server   Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.   Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.   MariaDB [(none)]>

3）接下来进行MariaDB的相关简单配置，设置密码，会提示先输入密码

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

[[email protected] yum.repos.d]# 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):      <–初次运行直接回车     设置密码 Set root password? [Y/n]                               <– 是否设置root用户密码，输入y并回车或直接回车 New password:                                          <– 设置root用户的密码，比如密码为123456 Re-enter new password:                                 <– 再输入一次你设置的密码     其他配置 Remove anonymous users? [Y/n]                          <– 是否删除匿名用户，回车 Disallow root login remotely? [Y/n]                    <–是否禁止root远程登录,回车, Remove test database and access to it? [Y/n]           <– 是否删除test数据库，回车 Reload privilege tables now? [Y/n]                     <– 是否重新加载权限表，回车   [[email protected] yum.repos.d]# mysql -p123456 Welcome to the MariaDB monitor.  Commands end with ; or \g. Your MariaDB connection id is 19 Server version: 10.3.5-MariaDB MariaDB Server   Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.   Type ‘help;‘ or ‘\h‘ for help.

4）接下来配置MariaDB的字符集

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64

[[email protected] yum.repos.d]# cat /etc/my.cnf # # This group is read both both by the client and the server # use it for options that affect everything # [client-server]   # # include all files from the config directory # !includedir /etc/my.cnf.d                              //说明在该配置文件中引入/etc/my.cnf.d 目录下的配置文件   [[email protected] yum.repos.d]# ls /etc/my.cnf.d/ enable_encryption.preset  mysql-clients.cnf  server.cnf   首先是配置文件/etc/my.cnf.d/server.cnf，在[mysqld]标签下添加 init_connect=‘SET collation_connection = utf8_unicode_ci‘ init_connect=‘SET NAMES utf8‘ character-set-server=utf8 collation-server=utf8_unicode_ci skip-character-set-client-handshake   然后配置文件/etc/my.cnf.d/mysql-clients.cnf，在[mysql]中添加 default-character-set=utf8   最后是重启MariaDB，并登陆MariaDB查看字符集 [[email protected] yum.repos.d]# /etc/init.d/mysql restart Shutting down MariaDB.. SUCCESS! Starting MariaDB.180313 05:47:41 mysqld_safe Logging to ‘/var/lib/mysql/centos6-test08.err‘. 180313 05:47:41 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql  SUCCESS!   [[email protected] yum.repos.d]# mysql -p123456 Welcome to the MariaDB monitor.  Commands end with ; or \g. Your MariaDB connection id is 9 Server version: 10.3.5-MariaDB MariaDB Server   Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.   Type ‘help;‘ or ‘\h‘ for help.
