CentOS MySQL 5.7編譯安裝

CentOS　MySQL 5.7編譯安裝

MySQL 5.7 GA版本的發布，也就是說從現在開始5.7已經可以在生產環境中使用，有任何問題官方都將立刻修復。

MySQL 5.7主要特性：

• 更好的性能：對于多核CPU、固態硬盤、鎖有著更好的優化，每秒100W QPS已不再是MySQL的追求，下個版本能否上200W QPS才是吾等用戶更關心的
• 更好的InnoDB存儲引擎
• 更為健壯的復制功能：復制帶來了數據完全不丟失的方案，傳統金融客戶也可以選擇使用MySQL數據庫。此外，GTID在線平滑升級也變得可能
• 更好的優化器：優化器代碼重構的意義將在這個版本及以后的版本中帶來巨大的改進，Oracle官方正在解決MySQL之前最大的難題
• 原生JSON類型的支持
• 更好的地理信息服務支持：InnoDB原生支持地理位置類型，支持GeoJSON，GeoHash特性
• 新增sys庫：以后這會是DBA訪問最頻繁的庫

MySQL 5.7已經作為數據庫可選項添加到《OneinStack》

編譯安裝

?

1 2	make -j `grep processor /proc/cpuinfo | wc -l` #編譯很消耗系統資源，小內存可能編譯通不過 make install

啟動腳本，設置開機自啟動

初始化數據庫

注：

• 之前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目錄下,且已被廢棄
• "--initialize"會生成一個隨機密碼(~/.mysql_secret)，而"--initialize-insecure"不會生成密碼
• --datadir目標目錄下不能有數據文件

啟動數據庫

?

1	/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
