我在运行我的 mysql docker 时遇到了一些麻烦。这是我的错误：
testmysql | + echo 'Finished mysql_install_db'
testmysql | Finished mysql_install_db
testmysql | + pid=59
testmysql | + mysql=(mysql --protocol=socket -uroot -hlocalhost --socket=/var/run/mysqld/mysqld.sock)
testmysql | + for i in '{30..0}'
testmysql | + mysqld --verbose --skip-networking --socket=/var/run/mysqld/mysqld.sock
testmysql | + echo 'SELECT 1'
testmysql | + mysql --protocol=socket -uroot -hlocalhost '--socket=/var/run/mysqld/mysqld.sock --verbose'
testmysql | + echo 'MySQL init process in progress...'
testmysql | + sleep 1
testmysql | MySQL init process in progress...
