服务器安装centos7.9步骤

戴尔T430安装步骤

1. 准备centos7.9的安装镜像u盘
2. 插入u盘按住F11选择u盘优先启动项
3. 选择储存位置将原有的磁盘删除选择我要配置分区
4. 删除原有磁盘的分区，点击自动创建将home目录设置150G，其余容量给/目录，点击完成
5. 选择安装软件选择，选择java平台、gnome桌面、基本开发环境
6. 设置管理员密码sy123@，添加一个用户 admin hykj2023
7. 开始安装
8. 安装完成，拔掉u盘重启服务器进入linux系统
9. 进入root权限账户，删除添加的用户，设置root用户为第一登录选择

设置root用户为第一登录选择

vi /etc/gdm/custom.conf

[daemon]
AutomaticLoginEnable=True
AutomaticLogin=root

chmod +x /etc/gdm/custom.conf

docker

docker安装地址

curl -sSL https://get.daocloud.io/docker | sh
或 
    curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
启动
    systemctl start docker
或
service docker start

docker开机启动

systemctl enable docker

离线安装docker

1.下载docker 离线包 https://download.docker.com/linux/static/stable/x86_64/

tar -xvf docker-24.0.7.tgz #解压
cp docker/* /usr/bin/   #将解压出来的docker文件内容移动到 /usr/bin/ 目录下+

2.docker 注册为服务
vim /etc/systemd/system/docker.service  #修改如下
chmod +x /etc/systemd/system/docker.service #添加文件权限
systemctl daemon-reload #重载unit配置文件
systemctl start docker #
systemctl enable docker.service

补充配置文件 docker.service

gzip -c spm.tar >spm.tar.gz
#docker 将tar包 加载为镜像
docker load --input spm.tar.gz
docker rmi IMAGE ID #删除指定镜像
docker stop [容器ID或名称] #停止容器
docker start [容器ID或名称] #启动容器


#删除历史的卷 镜像包修改后需要执行
docker volume rm $(docker volume ls -qf dangling=true)

开放数据库远程连接权限

1、连接服务器: mysql -u root -p

2、查看当前所有数据库：show databases;

3、进入mysql数据库：use mysql;

4、查看mysql数据库中所有的表：show tables;

5、查看user表中的数据：select host,user from user;

6、修改user表update user set host=‘%’ where user=‘root’;

7、刷新flush privileges;

宝塔面板mysql配置修改添加

group_concat_max_len = 999999、skip_ssl

服务器raid5问题处理

1. 将服务器数据所有数据清除，五块磁盘组raid5

2. 进入bios启动界面，按住ctrl+r进入磁盘管理

3. 解决办法如下

数据同步

1. 井队新建和线上一样的数据库
2. cloud_down_sync_config、drilling_crew_up_sync_config 两张表创建时间改为当前最新时间两小时后（避免同步重复数据）
3. 复制一张表到本地数据库触发同步数据，取消选中
breakdown_error_data、
breakdown_info、
cloud_mq_sync_log、
cloud_sync_instructions_record、
current_mean_table、
current_table、
device_online_record、
three_current、
top_drive_monitor、
top_drive_monitor_second、
top_drive_monitor_his的所有表、
vibration_table、
名称带时间的表（如：three_d_solution_info_20231023）
4. 数据同步完后，同步表结构
breakdown_info、
breakdown_error_data、
cloud_mq_sync_log、
cloud_sync_instructions_record、
current_mean_table、
current_table、
device_online_record、
three_current、
top_drive_monitor、
top_drive_monitor_second、
vibration_table、
