1. linux安装mysql8.0.12,亲测可用。
以下是安装过程中出现的问题:
1 [[email protected] file]# systemctl start mysqld 2 Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details. 3 4 [[email protected] file]# systemctl status mysqld 5 ● mysqld.service - MySQL Server 6 Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) 7 Active: failed (Result: exit-code) since Tue 2018-09-11 19:58:27 CST; 15s ago 8 Docs: man:mysqld(8) 9 http://dev.mysql.com/doc/refman/en/using-systemd.html 10 Process: 29481 ExecStart=/usr/sbin/mysqld $MYSQLD_OPTS (code=exited, status=1/FAILURE) 11 Process: 29454 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS) 12 Main PID: 29481 (code=exited, status=1/FAILURE) 13 Status: "SERVER_BOOTING" 14 Error: 98 (Address already in use) 15 16 Sep 11 19:58:23 localtest1.guandata.com systemd[1]: Starting MySQL Server... 17 Sep 11 19:58:27 localtest1.guandata.com systemd[1]: mysqld.service: main process exited, code=exited, status=1/FAILURE 18 Sep 11 19:58:27 localtest1.guandata.com systemd[1]: Failed to start MySQL Server. 19 Sep 11 19:58:27 localtest1.guandata.com systemd[1]: Unit mysqld.service entered failed state. 20 Sep 11 19:58:27 localtest1.guandata.com systemd[1]: mysqld.service failed. 21 [[email protected] file]# lsof -i :3306 22 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME 23 docker-pr 17413 root 4u IPv6 23187758 0t0 TCP *:mysql (LISTEN) 24 25 原因:docker中已使用mysql并占用3306端口。由于我是测试自己的项目,就改了自己的mysql的端口号,重新装了一个mysql。
修改mysql端口号: [[email protected] file]# vi /etc/my.cnf 增加行: port=7566
2. 安装过程中会用到的linux命令
1 启动mysqld服务 2 systemctl start mysqld 3 4 查看mysqld状态 5 systemctl status mysqld 6 7 查看mysql日志 8 tail -n 100 /var/log/mysqld.log 9 10 列出谁在使用某个端口(https://www.cnblogs.com/sparkbj/p/7161669.html) 11 lsof -i :7566 12 13 netstat命令用来打印Linux中网络系统的状态信息 14 netstat -anp|grep 0715
