好了。下面就可以进行安装MySQL了。
安装MySQL
我这里也是使用MySQL5.7来安装的。
我们只需要执行以下命令就OK了：
1
yum install mysql-community-server
#MySQL 管理命令
使用下面的命令启动MySQL：
1 2
[root@localhost ~]# service mysqld start Redirecting to /bin/systemctl start mysqld.service
只要没有错误信息就表示已经正常启动了。
现在我们看以下MySQL的状态：
1 2 3 4 5 6 7 8 9 10 11 12 13
[root@localhost ~]# service mysqld status Redirecting to /bin/systemctl status mysqld.service ● mysqld.service - MySQL Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) Active: active (running) since 一 2016-11-14 12:34:44 CST; 5min ago Process: 35494 ExecStart=/usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid $MYSQLD_OPTS (code=exited, status=0/SUCCESS) Process: 35421 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS) Main PID: 35498 (mysqld) CGroup: /system.slice/mysqld.service └─35498 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid
11月 14 12:34:39 localhost.localdomain systemd[1]: Starting MySQL Server... 11月 14 12:34:44 localhost.localdomain systemd[1]: Started MySQL Server.
这样表示已经正常启动了。
停止：
1
service mysqld stop
重启：
1
service mysqld restart
修改MySQL密码
我们首先查找一下MySQL的密码：
1 2
[root@localhost ~]# grep 'temporary password' /var/log/mysqld.log 2016-11-14T04:34:41.742516Z 1 [Note] A temporary password is generated for root@localhost: sNKz9yEdzw%/
我们就可以看到我们的密码就是： **sNKz9yEdzw%/**。
首先启动MySQL client:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
[root@localhost ~]# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.16

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql>
首先我们先查看一下数据库：
1 2
mysql>show databases; ERROR 1820 (HY000): You must reset your password usingALTERUSER statement before executing this statement.
