服务器安装centos7.9步骤

戴尔T430安装步骤

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

服务环境安装

宝塔安装（公网环境下）

yum install -y wget && wget -O install.sh http://download.bt.cn/install/install_6.0.sh && sh install.sh ed8484bec

Nginx1.22.1

# 解压nginx软件包
tar -zxvf nginx-1.22.1.tar.gz -C /usr/local/srccd /usr/local/src/nginx-1.22.1/
# 安装编译环境
yum install -y gcc gcc-c++ pcre pcre-devel zlib zlib-devel
# 预编译
./configure –prefix=/usr/local/nginx
# 编译安装
make
ma keinstall

# 修改配置文件端口
vim /usr/local/nginx/conf/nginx.conf
# 进入启动目录，启动服务
cd /usr/local/nginx/sbin./nginx
# 快速停止
./nginx -s stop# 优雅关闭，在退出前完成已经接受的连接请求
./nginx-s quit
# 重新加载配置
/nginx -s reload

# 编辑服务脚本
vim /usr/lib/systemd/system/nginx.service

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

docker进入容器
docker exec -it spm /bin/bash
#文件:主机->容器
docker cp spm-1.0-SNAPSHOT.jar spm:/usr/local/server/java/spm/
#文件:容器->主机
docker cp spm:/usr/local/server/java/spm/spm-1.0-SNAPSHOT.jar /mydata/
#刷新配置
supervisorctl -c /usr/local/server/supervisor/config/supervisord.conf update

#docker build 打包基于Dockerfile
docker build -t spm:1.0.0 .
docker build -t visor:1 .

#docker save 命令用于将 Docker 镜像保存为 tar 文件
docker save -o spm.tar spm:1.0.19
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)

#运行容器 注意版本号
docker run -d –name=spm –restart=always -v /etc/localtime:/etc/localtime:ro -v /data/bvdata/data:/data/bvdata/data:ro -v /usr/local/oss:/usr/local/oss -v /data/spmdata/data:/usr/local/server/data -v /data/spmdata/config:/usr/local/server/config -v /data/spmdata/logs/sync:/usr/local/server/logs/sync -v /data/spmdata/logs/sync-client:/usr/local/server/logs/sync-client -v /data/spmdata/logs/xxl-job:/usr/local/server/logs/xxl-job -v /data/spmdata/logs/spm:/usr/local/server/java/spm/logs -v /data/spmdata/logs/spm-admin:/usr/local/server/java/spm-admin/logs –network=host spm:1.0.21

更换阿里云镜像源

cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo-bak #备份
rm -f /etc/yum.repos.d/CentOS-Base.repo # 删除旧文件
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo #在线下载aliyun镜像

jdk环境配置

vim /etc/profile #打开配置文件内容
# set java evironment 配置文件如下
JAVA_HOME=/usr/local/java/jdk/jdk1.8.0_361
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME
export PATH CLASSPATH
source /etc/profile #立即生效

redis配置

protected-mode no #第90行把yes 改为no

配 置完成后需要修改默认密码并重新启动redis

/www/server/redis/redis.conf 宝塔安装存储位置

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

tdengine配置

服务启动命令

#rpm 安装
rpm -ivh TDengine-server-3.0.4.0-Linux-x64.rpm
#启动tdengine
systemctl start taosd
#查看状态
systemctl status taosd
#自启动
systemctl enable taosd

修改密码

alter user root pass 'hykj2022';

创建库，用作存储井队动作事件
taos -uroot -phykj2022
create database spm_his;
use spm_his;
create stable top_driver_action(ts TIMESTAMP,drilling_crew_no nchar(20),device_info_no nchar(20),mapping_code nchar(20),data_group nchar(100),json_value varchar(15000),monitor_time TIMESTAMP) TAGS (month varchar(20));
td建表语句

emqx配置

服务启动命令

#rpm 安装
rpm -ivh emqx-5.5.0-el7-amd64.rpm
#启动emqx
systemctl start emqx
#查看状态
systemctl status emqx
#自启动
systemctl enable emqx

rocketmq配置

rocketmq 运行
# 1.关闭Nameserver
sh mqshutdown namesrv
# 2.关闭ker
sh mqshutdown broker
1.启动nameserver
nohup ./usr/local/software/rocketmq-all-4.7.1-bin-release/bin/mqnamesrv -n 192.168.110.244:9876 &
启动mqbroker
nohup ./usr/local/software/rocketmq-all-4.7.1-bin-release/bin/mqbroker -n 192.168.110.244:9876 -c ../conf/broker.conf autoCreateTopicEnable=true &

服务器raid5问题处理

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、

shell脚本

查看端口

#coding: utf-8
import os
import sys
os.chdir('/www/server/panel')
sys.path.insert(0,'class/')
import public
import socket
arg = sys.argv[-1]
ip,port = arg.split(':')
try:
s = socket.socket()
s.settimeout(0.15)
s.connect((ip,int(port)))
s.close()
except:
print('closed')
sys.exit(1)

print('open')

linux语法

修改服务器ip方法

vim /etc/sysconfig/network-scripts/ifcfg-em1

BOOTPROT0=static #启用静态IP地址
ONB00T=yes #开机自动启用网络连接

systemctl restart network

查看磁盘使用情况命令Linux

df -h：以人类可读的格式（如 KB、MB、GB）显示磁盘使用情况。

df -T：显示文件系统的类型。

df -a：显示所有文件系统的磁盘使用情况，包括特殊文件系统如 /proc。df -h

linux查看所有开放的端口

netstat -tuln

ys os.chdir(‘/www/server/panel’) sys.path.insert(0,‘class/’) import public import socket arg = sys.argv[-1] ip,port = arg.split(‘:’) try: s = socket.socket() s.settimeout(0.15) s.connect((ip,int(port))) s.close() except: print(‘closed’) sys.exit(1)
