查看MYSQL启动时间 mysql查看启动日志

mysql有以下几种日志：
   错误日志：     -log-err
   查询日志：     -log
   慢查询日志:   -log-slow-queries
   更新日志:     -log-update
   二进制日志： -log-bin

顯示二進制日志數目

mysql> show master logs;

看二进制日志文件用

mysqlbinlog 
 shell>mysqlbinlog mail-bin.000001 
 或者shell>mysqlbinlog mail-bin.000001 | tail

1.首先确认是否启用了日志

mysql> show variables like 'log_bin';
 +---------------+-------+
 | Variable_name | Value |
 +---------------+-------+
 | log_bin       | ON    |
 +---------------+-------+
 1 row in set (0.00 sec)
 mysql>

2.如果启用了，即ON
那日志文件就在mysql的安装目录的data目录下

3.怎样知道当前的日志

mysql> show master status;
 +------------------+----------+--------------+------------------+
 | File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
 +------------------+----------+--------------+------------------+
 | mysql-bin.000014 | 22029080 |              |                  |
 +------------------+----------+--------------+------------------+
 1 row in set (0.00 sec) 
 mysql>

                                                                                                                                  

 

 4.看二进制日志文件用

mysqlbinlog
 #/usr/local/mysqlbin/mysqlbinlog mail-bin.0000014
 或者mysqlbinlog mail-bin.0000014 | tail

在linux下：
Sql代码

1. # 在[mysqld] 中輸入  
    2. #log  
    3. log-error=/usr/local/mysql/log/error.log  
    4. log=/usr/local/mysql/log/mysql.log  
    5. long_query_time=2  
    6. log-slow-queries= /usr/local/mysql/log/slowquery.log  

 # 在[mysqld] 中輸入 
 #log 
 log-error=/usr/local/mysql/log/error.log 
 log=/usr/local/mysql/log/mysql.log 
 long_query_time=2 
 log-slow-queries= /usr/local/mysql/log/slowquery.log
