apt搜索一下
$ sudo apt search mytop Sorting... Done Full Text Search... Done mytop/focal,focal,now 1.9.1-4 all top like query monitor for MySQL
然後安裝一下
sudo apt-get install mytop
直接執行 mytop 報錯
$ mytop Cannot connect to MySQL server. Please check the: * database you specified "" (default is "") * username you specified "root" (default is "root") * password you specified "" (default is "") * hostname you specified "localhost" (default is "localhost") * port you specified "3306" (default is 3306) * socket you specified "" (default is "") The options my be specified on the command-line or in a ~/.mytop or ~/.my.cnf config file. See the manual (perldoc mytop) for details. Here's the exact error from DBI. It might help you debug: Access denied for user 'root'@'localhost' (using password: NO)
說我沒有找到 .mytop 或者 my.cnf 文件，那麼這個文件應該怎麼配置呢？通過find尋找發現了跟mytop有關的文件夾
$ sudo find / -name "mytop" find: ‘/proc/2308/task/2308/net’: Invalid argument find: ‘/proc/2308/net’: Invalid argument find: ‘/run/user/1001/doc’: Permission denied find: ‘/run/user/1001/gvfs’: Permission denied /usr/bin/mytop /usr/share/doc/mytop
這個就是可執行文件，不是它
$ ll /usr/bin/mytop -rwxr-xr-x 1 root root 60K 1月 10 2017 /usr/bin/mytop*
發現這個有配置，然後查看一下這個默認配置有個參考
$ ll /usr/share/doc/mytop total 12K -rw-r--r-- 1 root root 2.2K 1月 10 2017 changelog.Debian.gz -rw-r--r-- 1 root root 1.3K 1月 10 2017 copyright -rw-r--r-- 1 root root 871 1月 10 2017 mytop.sample.conf
發現了這個 simple conf 。好了，如此以來應該是要按這個配置，看一下它的內容
# Copy this file to ~/.mytop and customize it to your own needs # Username to use when logging in to the MySQL server user=root # Password to use when logging in to the MySQL server pass= # Hostname of the MySQL server. host=localhost # Port number of the MySQL server. port=3306 # Connect to specific database by default. db=test # How long between display refreshes. delay=5 # Use direct socket instead of TCP/IP network to connect to the MySQL server. socket= # Run mytop only once and than exit. batchmode=0 # Display headers or not. header=1 # Use colors if available. color=1 # Display idle threads. idle=1 # Resolve IP addresses to names. resolve=1 # Compact large numbers for better readability, e.g. 10.000 -> 10.0k. long=0 # Reverse sort order from ascending to descending using Idle time. sort=0 # Use vt100 escape sequences to reduce screen flicker. vt100=0
然後配置一份文件到
touch ~/.mytop
這個文件裏面配置如下內容
# Copy this file to ~/.mytop and customize it to your own needs # Username to use when logging in to the MySQL server user=root # Password to use when logging in to the MySQL server pass=密碼 # Hostname of the MySQL server. host=localhost # Port number of the MySQL server. port=3306 # Connect to specific database by default. db=test # How long between display refreshes. delay=5 # Use direct socket instead of TCP/IP network to connect to the MySQL server. socket=/tmp/mysql.sock # Run mytop only once and than exit. batchmode=0 # Display headers or not. header=1 # Use colors if available. color=1 # Display idle threads. idle=1 # Resolve IP addresses to names. resolve=1 # Compact large numbers for better readability, e.g. 10.000 -> 10.0k. long=0 # Reverse sort order from ascending to descending using Idle time. sort=0 # Use vt100 escape sequences to reduce screen flicker. vt100=0
如此以來就配置好了。重新啓動一下看看。
$ mytop
得到
這樣以來就可以用它監控mysql 的 qps 了
