Centos6下使用yum安裝MariaDB

1）增長mariaDB的yum源

1 2 3 4 5 6 7 8 9

[root@centos6-test08 ~]# cd /etc/yum.repos.d/ [root@centos6-test08 yum.repos.d]# cp CentOS-Base.repo CentOS-Base.repo.bak [root@centos6-test08 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安裝MariaDB

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

[root@centos6-test08 yum.repos.d]# yum install -y MariaDB-server MariaDB MariaDB-client   安裝好後，啓動服務 [root@centos6-test08 yum.repos.d]# /etc/init.d/mysql start [root@centos6-test08 yum.repos.d]# ps -ef|grep mysql [root@centos6-test08 yum.repos.d]# lsof -i:3306   設置開機啓動 [root@centos6-test08 yum.repos.d]# chkconfig mysql on   [root@centos6-test08 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）接下來進行MariaDB的相關簡單配置，設置密碼，會提示先輸入密碼

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

[root@centos6-test08 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):      <–初次運行直接回車     設置密碼 Set root password? [Y/n]                               <– 是否設置root用戶密碼，輸入y並回車或直接回車 New password:                                          <– 設置root用戶的密碼，好比密碼爲123456 Re-enter new password:                                 <– 再輸入一次你設置的密碼     其餘配置 Remove anonymous users? [Y/n]                          <– 是否刪除匿名用戶，回車 Disallow root login remotely? [Y/n]                    <–是否禁止root遠程登陸,回車, Remove test database and access to it? [Y/n]           <– 是否刪除test數據庫，回車 Reload privilege tables now? [Y/n]                     <– 是否從新加載權限表，回車   [root@centos6-test08 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. Type '\c' to clear the current input statement.   MariaDB [(none)]> show databases; +--------------------+ | Database           | +--------------------+ | information_schema | | mysql              | | performance_schema | +--------------------+ 3 rows in set (0.001 sec)

4）接下來配置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

[root@centos6-test08 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                              //說明在該配置文件中引入/etc/my.cnf.d 目錄下的配置文件   [root@centos6-test08 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]標籤下添加 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   而後配置文件/etc/my.cnf.d/mysql-clients.cnf，在[mysql]中添加 default-character-set=utf8   最後是重啓MariaDB，並登錄MariaDB查看字符集 [root@centos6-test08 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!   [root@centos6-test08 yum.repos.d]# mysql -p123456 Welcome to the MariaDB monitor.  Commands end with ; or \g.
