安裝mariadb
通過yum;或者自行下載RPM 和依賴包安裝。***** 將/var/lib/mysql 下的檔案,複製到所需的資料檔案目錄。修改所屬使用者和組。
3.編輯MariaDB 配置檔案
編輯/etc/my.cnf.d/server.cnf ,或者/etc/my.cnf 檔案
# # These groups are read by MariaDB server. # Use it for options that only the server (but not clients) should see # # See the examples of server my.cnf files in /usr/share/mysql/ # # this is read by the standalone daemon and embedded servers [client] socket=/u01/mysql/data/mysql.sock [server] socket=/u01/mysql/data/mysql.sock datadir=/u01/mysql/data [mysqld] [galera] [embedded] [mariadb] [mariadb-10.4]
可能遇到的問題
