新安装的MySQL的简单配置

修改配置文件

 

bind-address = 10.6.20.1
port = 3306
character_set_server = utf8
max_connect_errors = 1000000
max_connections = 500
datadir = /data/mysql
log-error = /var/log/mysql/mysql-error.log-error
skip_name_resolve
back_log = 2000
log-bin = /data/mysql
binlog-format = MIXED
expire_logs_days = 2

  

 

新安装的MySQL的简单配置

bind-address:监听的IP地址

max_connect_errors:最大允许错误次数(注:是访问协议错误,若某个IP错误次数达到该阈值,则被屏蔽)

max_connections :最大连接数(能同时访问server的连接个数,若达到该阈值,则不能再连接到server)

skip_name_resolve :跳过域名反解

back_log :创建TCP连接时,允许的最大同时未完成的连接个数

expire_logs_days :binlog的保留天数

注:

datadir和log-error和log-bin等对应目录需要确保已创建,并且权限为mysql所有。

例如:

mkdir -p /data/mysql

chown -R mysql.mysql /data/mysql

 

mkdir -p /var/log/mysql

chown -R mysql.mysql /var/log/mysql

 

配置完成后,启动mysql:

/etc/init.d/mysqld start

 
 mysql> SELECT user,host FROM MYSQL.USER;

+------+-----------+
| user | host |
+------+-----------+
| root | 127.0.0.1 |
| root | ::1 |
| | localhost |
| root | localhost |
+------+-----------+
4 rows in set (0.00 sec) mysql> DROP USER ''@localhost;
Query OK, 0 rows affected (0.25 sec) mysql> DROP USER 'root'@'::1';
Query OK, 0 rows affected (0.00 sec) mysql> SELECT user,host FROM MYSQL.USER;
+------+-----------+
| user | host |
+------+-----------+
| root | 127.0.0.1 |
| root | localhost |
+------+-----------+
2 rows in set (0.00 sec)

  

为root用户赋予密码:

mysql> UPDATE mysql.user SET password = PASSWORD('newpassword') WHERE user = 'root';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 3 Changed: 0 Warnings: 0 mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec) mysql> quit
Bye
