標籤:mysql 資料庫 設定檔
錯誤1:資料庫做遷移時,往往會出現各種問題,比如performance_schema,資料庫perfor這個出錯,可以嘗試用此命令修複:
mysql_upgrade -u root -p mysql_upgrade -u root -p --force
錯誤2:找不到指定的innodb目錄。
在my.cnf設定檔中添加如下參數:
innodb_data_home_dir = /home/data/databaseinnodb_data_file_path = ibdata1:10M:autoextendinnodb_log_group_home_dir = /home/data/database
這裡說一下正確遷移資料庫的步驟:
1)初始化資料庫目錄:/datamysqld --initialize-insecure --basedir=/usr/local/mysql --datadir=/home/data/database --user=mysql --server-id=502)刪除初始化目錄下的檔案:rm -rf ibdata1 iblogfile1 iblogfile2 mysql 3)把複製的資料庫拷貝到初始化的目錄下cp mysql ibdata1 iblogfile1 iblogfile2 /data/ 4)mysql_upgrade -u root -p #這一步至關重要,一般能解決遷移時所有問題。
拷貝的資料庫可能出現各種錯誤,此時需要在my.cnf設定檔中設定innodb_force_recovery=1 ,重啟mysql,如果出錯改為2一直到6試試。
錯誤3:遷移完資料庫配置主從複製時,總是提示least set server_id:
刪除mysql下的5張表。
drop table if exists innodb_index_stats;drop table if exists innodb_table_stats;drop table if exists slave_master_info;drop table if exists slave_relay_log_info;drop table if exists slave_worker_info;
然後刪除:/data/mysql下相關的.frm .ibd檔案 #如果沒有則無需刪除
rm -rf innodb_index_stats*rm -rf innodb_table_stats*rm -rf slave_master_info*rm -rf slave_relay_log_info*rm -rf slave_worker_info*
登入資料庫:> source /usr/local/mysql/share/mysql_system_tables.sql #此命令不行的話需要重建立表。
