No need to type in the password, just use any one of these commands (self explanatory):
mysqlcheck --all-databases -a #analyze
mysqlcheck --all-databases -r #repair
mysqlcheck --all-databases -o #optimize
The following command worked for me using the command prompt (As an Administrator) in Windows:
mysqlcheck -u root -p -A --auto-repair
Run mysqlcheck with the root user, prompt for a password, check all databases, and auto-repair any corrupted tables.
The command is this:
mysqlcheck -u root -p --auto-repair --check --all-databases
You must supply the password when asked,
or you can run this one but it's not recommended because the password is written in clear text:
mysqlcheck -u root --password=THEPASSWORD --auto-repair --check --all-databases
There is no default command to do that, but you may create a procedure to do the job.
It will iterate through rows of information_schema
and call REPAIR TABLE 'tablename';
for every row. CHECK TABLE
is not yet supported for prepared statements. Here's the example (replace MYDATABASE with your database name):
CREATE DEFINER = 'root'@'localhost'
PROCEDURE MYDATABASE.repair_all()
BEGIN
DECLARE endloop INT DEFAULT 0;
DECLARE tableName char(100);
DECLARE rCursor CURSOR FOR SELECT `TABLE_NAME` FROM `information_schema`.`TABLES` WHERE `TABLE_SCHEMA`=DATABASE();
DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET endloop=1;
OPEN rCursor;
FETCH rCursor INTO tableName;
WHILE endloop = 0 DO
SET @sql = CONCAT("REPAIR TABLE `", tableName, "`");
PREPARE statement FROM @sql;
EXECUTE statement;
FETCH rCursor INTO tableName;
END WHILE;
CLOSE rCursor;
END
If corrupted tables remain after
mysqlcheck -A --auto-repair
try
mysqlcheck -A --auto-repair --use-frm
I like this for a simple check from the shell:
mysql -p<password> -D<database> -B -e "SHOW TABLES LIKE 'User%'" \
| awk 'NR != 1 {print "CHECK TABLE "$1";"}' \
| mysql -p<password> -D<database>
You may need user name and password:
mysqlcheck -A --auto-repair -uroot -p
You will be prompted for password.
mysqlcheck -A --auto-repair -uroot -p{{password here}}
If you want to put in cron, BUT your password will be visible in plain text!
from command line you can use:
mysqlcheck -A --auto-repair
Use following query to print REPAIR
SQL statments for all tables inside a database:
select concat('REPAIR TABLE ', table_name, ';') from information_schema.tables
where table_schema='mydatabase';
After that copy all the queries and execute it on mydatabase
.
Note: replace mydatabase
with desired DB name
for plesk hosts, one of these should do: (both do the same)
mysqlrepair -uadmin -p$(cat /etc/psa/.psa.shadow) -A
# or
mysqlcheck -uadmin -p$(cat /etc/psa/.psa.shadow) --repair -A
