innodb_lock_wait_timeout can be set at runtime with the SET GLOBAL or SET SESSION statement. 可以在运行时使用SET GLOBAL或SET SESSION语句设置innodb_lock_wait_timeout。 Changing the GLOBAL setting requires the SUPER privilege and affects the operation of all clients that subsequently connect.
更改GLOBAL设置需要SUPER特权,并影响随后连接的所有客户端的操作。 Any client can change the SESSION setting for innodb_lock_wait_timeout, which affects only that client.
任何客户端都可以更改innodb_lock_wait_timeout的SESSION设置,这仅影响该客户端。
You may also change the config file my.cnf and add innodb_lock_wait_timeout=900. 您也可以更改配置文件my.cnf并添加innodb_lock_wait_timeout = 900。
