Linux 沒有 my.cnf 解決方案檔案完全我自己的整個教程很多口才

標籤：

我看過好多關於Linux下沒有my.cnf的部落格，都是什麼rmp安裝沒有my.cnf檔案啊，然後什麼兩個方法啊，我就無語了，大家要是知道就不會查資料了，你們敢不敢負責點？說具體點？有的說從 /usr/share/mysql 裡複製一個.cnf檔案到 /etc 下，實用嗎？設定檔資料不給別人，複製個毛線？複製誰都會！

my.cnf 設定檔：

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the# *** default location during install, and will be replaced if you# *** upgrade to a newer version of MySQL.[mysqld]#innodb# Remove leading # and set to the amount of RAM for the most important data# cache in MySQL.

假設上述檔案配置好後，運行mysql登入，拋出xxxx.line 這種異常，就去 /usr/share/mysql 以下複製一個.cnf檔案的頭部替換掉上述my.cnf的頭部代碼，前提是要copy一個到/etc下，命名my.cnf，再把上面的copy，版本號碼資訊和一些具體檔案的

詳細路徑配置，和參數配置看你自己的安裝情況

我替換的是/usr/share/mysql/my-default.cnf 標頭檔的這幾句：

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the# *** default location during install, and will be replaced if you# *** upgrade to a newer version of MySQL.[mysqld]

然後[mysqlld]下面的所有是copy上面的，從上面設定檔的第7行的#號開始，能夠解決類似 Fatal error in defaults handling. Program aborted 或者xxxx line xxxx 錯誤的問題，依據你server的詳細情況詳細分析，我的是以我配置的為基準的

配置完之後，mysql能夠正常登入，查看和開機記錄：

須要開啟的能夠自己設定，希望能夠幫到大家，少走歪路！
