為MySQL5.6加上5.7才有的sys庫
阿新 • • 發佈：2018-12-31
MySQL5.7.7引入的sys庫可以看作是由information_schema引出的一套檢視，更便於獲取一些效能資料。
下面我會記錄如何為MySQL5.6加上sys庫。
首先從https://github.com/mysql/mysql-sys上克隆專案到本地
假設存放在/tmp/mysql-sys下（注意檔案許可權為root，執行的可以是擁有invoke許可權的使用者）
[[email protected]_21 tmp]# git clone https://github.com/mysql/mysql-sys.git Initialized empty Git repository in /tmp/mysql-sys/.git/ remote: Counting objects: 3009, done. remote: Total 3009 (delta 0), reused 0 (delta 0), pack-reused 3009 Receiving objects: 100% (3009/3009), 1.17 MiB | 205 KiB/s, done. Resolving deltas: 100% (1770/1770), done. [[email protected]_21 tmp]# ll mysql-sys/ total 380 -rw-r--r-- 1 root root 782 Oct 30 11:12 after_setup.sql -rw-r--r-- 1 root root 891 Oct 30 11:12 before_setup.sql -rw-r--r-- 1 root root 17987 Oct 30 11:12 COPYING drwxr-xr-x 2 root root 4096 Oct 30 11:12 functions -rwxr-xr-x 1 root root 7842 Oct 30 11:12 generate_sql_file.sh -rw-r--r-- 1 root root 707 Oct 30 11:12 LICENSE drwxr-xr-x 3 root root 4096 Oct 30 11:12 mysql-test -rw-r--r-- 1 root root 20596 Oct 30 11:12 NEWS.md drwxr-xr-x 2 root root 4096 Oct 30 11:12 procedures -rw-r--r-- 1 root root 270716 Oct 30 11:12 README.md -rw-r--r-- 1 root root 7613 Oct 30 11:12 sys_56.sql -rw-r--r-- 1 root root 8366 Oct 30 11:12 sys_57.sql drwxr-xr-x 2 root root 4096 Oct 30 11:12 tables drwxr-xr-x 2 root root 4096 Oct 30 11:12 templates drwxr-xr-x 2 root root 4096 Oct 30 11:12 triggers drwxr-xr-x 4 root root 4096 Oct 30 11:12 views
匯入出錯
[[email protected]_21 tmp]# mysql -uroot -p -S /tmp/mysql3306.sock < ./mysql-sys/sys_56.sql
Enter password:
ERROR at line 16: Failed to open file './before_setup.sql', error: 2修改檔案許可權：mysql:mysql後，可以正確匯入了
