max_allowed_packet = 16Mskip-name-resolve #跳过dns查询max_connections=1000#log-bin=mysql-bin #如果不使用主从配置,可以注释#binlog_format=mixeddefault-storage-engine=INNODB #设置默认引擎thread_concurrency = 16 #CPU逻辑线程数的2-4倍,我们搭载的CPU为8核心 × 2
3, 设置密码
[root@localhost mysql]# bin/mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!In order to log into MySQL to secure it, we'll need the currentpassword for the root user.
