可用于监控 mysql Master Slave 状态的python代码
复制代码 代码如下:
import os
import sys
import MySQLdb
def getStatus(conn):
query = \” SHOW SLAVE STATUS \”
# print query
cursor = conn.cursor()
cursor.execute(query)
result = cursor.fetchall()
return result[0]
def resolve(conn):
cursor = conn.cursor()
query1 = \”set global sql_slave_skip_counter=1\”
query2 = \”START SLAVE\”
query3 = \”SHOW SLAVE STATUS\”
cursor.execute(query1)
cursor.execute(query2)
cursor.execute(query3)
conn.commit()
if __name__ == \’__main__\’:
conn = MySQLdb.connect(read_default_file=\”~/.my.cnf\”, db=\”\”, port=3306, charset=\”utf8\”)
status = getStatus(conn)
print \”Master_Log_File: %s\” % status[5]
print \”Read_Master_Log_Pos: %s\” % status[6]
print \”Seconds_Behind_Master: %s\” % status[-1]
if status[32] is None:
resolve(conn)
else:
print \’resolved\’
