then

if [[ $# -ne 1 ]]
then

#根据情况修改变量信息
mysqluser="root"
mysqlpass="123456"
mysqlport=3398
mysqlsocket="/opt/mysql/$mysqlport/$mysqlport.sock"
currdate=$(date +%Y%m%d)
logpath="/root/checkslave"
logfile=$logpath/${currdate}
#各个错误代码解释
1158网络错误,出现读错误,请检查网络连接状况
1159网络错误,读超时,请检查网络连接状况
1008数据库不存在,删除数据库失败
1007数据库已存在,创建数据库失败
1062字段值重复,入库失败
1452不能删除或更新父行,外键约束失败
PS:1452这个根据情况跳过错误
