centos6.9安装mysql5.7.22并设置初始密码

  • 第一步:卸载以前版本或者自带lib包

 

[root@hdp01 apps]# rpm -qa |grep -i mysql mysql-libs-5.1.73-8.el6_8.x86_64

[root@hdp01 apps]# rpm -ev mysql-libs-* --nodeps



  • 第二步:安装相关安装包
[root@hdp01 apps]# rpm -ivh mysqlPackge/mysql-community-common-5.7.22-1.el6.x86_64.rpm
[root@hdp01 apps]# rpm -ivh mysqlPackge/mysql-community-libs-5.7.22-1.el6.x86_64.rpm
[root@hdp01 apps]# rpm -ivh mysqlPackge/mysql-community-client-5.7.22-1.el6.x86_64.rpm 
[root@hdp01 apps]# rpm -ivh mysqlPackge/mysql-community-client-5.7.22-1.el6.x86_64.rpm 
[root@hdp01 apps]# rpm -ivh mysqlPackge/mysql-community-server-5.7.22-1.el6.x86_64.rpm 
warning: mysqlPackge/mysql-community-server-5.7.22-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
    libnuma.so.1()(64bit) is needed by mysql-community-server-5.7.22-1.el6.x86_64
    libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-server-5.7.22-1.el6.x86_64
    libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-server-5.7.22-1.el6.x86_64

这里缺少相关依赖,解决方法:
[root@hdp01 apps]# yum install libnuma*
[root@hdp01 apps]# rpm -ivh mysqlPackge/mysql-community-server-5.7.22-1.el6.x86_64.rpm 
安装成功!

  • 第三步:修改初始密码

开启mysqld服务然后关闭,才会产生随机初始密码

 [root@hdp01 mysqlPackge]# service mysqld start

 [root@hdp01 mysqlPackge]# service mysqld stop

[root@hdp01 mysqlPackge]# cat /var/log/mysqld.log |more 找到下面这句话,标记处就是随机初始密码
2018-04-20T06:06:15.182041Z 1 [Note] A temporary password is generated for root@localhost: oWz=Ldt2KEfg

  [root@hdp01 mysqlPackge]# mysql -uroot -p
  Enter password:
  ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

  这里可能会报错(没有报错请忽略),解决办法:

    1)首先保证关闭mysql服务

      [root@hdp01 mysqlPackge]# service mysqld status
      mysqld is stopped

    2) 输入

      [root@hdp01 mysqlPackge]# sudo mysqld_safe --user=mysql --skip-grant-tables --skip-networking & 

      [5] 5781
      [root@hdp01 mysqlPackge]# 2018-04-20T06:07:57.907809Z mysqld_safe Logging to '/var/log/mysqld.log'.
      2018-04-20T06:07:57.943249Z mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

    3) 输入sudo mysql -u root mysql 进入数据库

    4) mysql> update user set password_expired = "Y" where user="root";

      mysql> flush privileges;

      mysql> quit

 

 [root@hdp01 mysqlPackge]# mysql -uroot -p
  Enter password:   这里的密码是随机初始密码

 再次进入,,成功  

 mysql> set password='mysql@1234'; 修改密码

  mysql> grant all privileges on *.* to 'root'@'%' identified by 'mysql@1234'; 允许远程访问   

 [root@hdp01 mysqlPackge]# chkconfig mysqld on  设置mysql开机自启动服务
