[root@iZ8vb7bjatr2sn0a6n2tncZ jdk]# ^C
[root@iZ8vb7bjatr2sn0a6n2tncZ jdk]# grep "password" /var/log/mysqld.log

这是已经安装了吧？登陆的时候需要查看默认密码怎么查看？
我尝试执行了【systemctl start mysqld】命令启动mysql；但是没有反应 ，提示如下？
[root@iZ8vb7bjatr2sn0a6n2tncZ ~]# systemctl start mysqld
Failed to start mysqld.service: Unit mysqld.service not found.
我想查看刚安装的数据库的默认密码
安装好后，先启动
[root@server ~]# systemctl start mysqld #启动mysql会生成临时密码（注意，别一上来就使用enable，会出现错误导致启动不了）
第一次通过# grep "password" /var/log/mysqld.log 命令获取MySQL的临时密码
[root@server ~]# mysql -uroot -p'&B=o4Fp!Rq_X' #注意临时密码要引号
所以，你是先启动，再去查，但你先明确是否安装正确，而且，看你安装的，不四海mysql 5.7 而是，mysql 8。。。
不过，8的操作，也一样，都是启动后，去找日志拿密码。
