mysqld.log 中没有临时密码
No temporary password in mysqld.log
我用的是mysql5.7.16社区和centos 7.
我正在关注视频 tutorial 以安装 mysql:
- wget http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
- yum localinstall dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
- yum repolist 已启用 | grep "mysql.-community."
- yum 安装mysql-社区服务器
- 服务mysqld 启动
启动 mysql 后,我可以看到状态为 alive (运行) service mysqld status
。
但是我什么也得不到:grep 'temporary password' /var/log/mysqld.log
msyqld.log(忽略正常日志):
[Warning] InnoDB: Cannot open table mysql/plugin from the internal data dictionary of InnoDB though the .frm file for the table exists.
mysqld: Table 'mysql.plugin' doesn't exist
[ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
[Warning] InnoDB: Cannot open table mysql/gtid_executed from the internal data dictionary of InnoDB though the .frm file for the table exists.
mysqld: Table 'mysql.gtid_executed' doesn't exist

[Warning] InnoDB: Cannot open table mysql/server_cost from the internal data dictionary of InnoDB though the .frm file for the table exists.

[Warning] Can't open and lock time zone table: Table 'mysql.time_zone_leap_second' doesn't exist trying to live without them
[Warning] InnoDB: Cannot open table mysql/servers from the internal data dictionary of InnoDB though the .frm file for the table exists.
[ERROR] Can't open and lock privilege tables: Table 'mysql.servers' doesn't exist
感谢任何帮助!
我想通了。
- 我安装的centos 7选择了mysql,mysql版本是5.5.
- 通过以下方式删除它:yum remove mysql-serverl.
- 按照本教程安装 5.7.16。
- 有这些错误。
- yum 删除 mysql-community-server,重新安装 5.7。
- 仍然有这些错误。
- Yum 删除 mysql-community-server,但删除目录 /var/lib/mysql.
- 然后重新安装,成功了。
关键是需要手动删除/var/lib/mysql。
如果没有密码,不用担心。
做吧。
sudo mysql_secure_installation
您没有密码,请按回车键。
我只是重新启动 mysql 并搜索:
service mysqld start
grep 'temporary password' /var/log/mysqld.log
已显示默认密码。
尝试
sudo grep 'temporary password' /var/log/mysqld.log | rev | cut -d" " -f1 | rev | tr -d "."
pwd
之后会显示。
