找不到mysqladmin命命设置密码,用
usr/bin/mysql_secure_installation 安装出现错误
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
是因为没有启动mysql /etc/init.d/mysql start
仍然出现无法连接问题
安装客户端 rpm -ivh MySQL-client-5.5.24-1.linux2.6.i386.rpm
- 设置root密码
设置: /usr/bin/mysqladmin -u root password root
更改密码方法1: /usr/bin/mysqladmin -u root -ppassword password newpassword
方法2:
mysql> use mysql; mysql> update user set password=PASSWORD("NEWPASSWORD") where User='vivek'; mysql> flush privileges; mysql> quit方法3 不知道旧密码重设mysql密码

测试时出现了个很诡异的现象 在旧的ssh 终端始终无法登陆 ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
新开终端则可以登录上,没弄清原因。
远程登录权限 grant select,update,insert,delete,create on *.* to root@ip identified by "root";http://www.sar4.com/2011/09/16/MYSQL%E5%AE%89%E5%85%A8%E8%AE%BE%E7%BD%AE.html mysql安全设置
- 复制
问题:找不到my.cnf的位置。
MySQL 的复制(Replication),实际上就是通过将Master 端的Binlog 通过利用IO 线 程通过网络复制到Slave 端,然后再通过SQL 线程解析Binlog 中的日志再应用到数据库中来实现的
mac 下 安装 mysql5.5 tar文件
http://dev.mysql.com/doc/refman/5.5/en/binary-installation.html
解压
scripts/mysql_install_db --user=mysql
shell> cp support-files/my-medium.cnf /etc/my.cnf
shell> bin/mysqld_safe --user=mysql &
# Next command is optional
cp support-files/mysql.server /etc/init.d/mysql.server
cp bin/mysql /user/sbin/.
设置密码 删掉旧用户即可
