Question

mysql开记二进制日志即配置my.cnf中的log_bin参数后无法正常启动，求高手解答！

mysql配置my.cnf中的log_bin参数后无法启动报错：
Starting MySQL.The server quit without updating PID file (/[FAILED]mysql/localhost.localdomain.pid).
my.cnf文件如下：
[mysqld]
log_bin= mysql-bin

basedir = /usr
datadir = /var/lib/mysql/
pid-file = /var/lib/mysql/localhost.localdomain.pid
port = 3306
# server_id = .....
socket = /var/lib/mysql/mysql.sock
都是默认配置，本来后面几行都是带#的，我怕它找不到试着加上路径，还是不行，求高手指点
自已给自己解答吧. 查看错误日志，里面显示：
[ERROR] You have enabled the binary log, but you haven't provided the mandatory server-id. Please refer to the proper server start-up parameters documentation

Answer 1

你在[mysqld]下，配置一个
server-id = 1
然后重启一下！

Answer 2

log-bin和server-id要一起设置，否则会报错
