CentOS7 安装 Docker

Centos7配置国内yum源和epel源


cd /etc/yum.repos.d/ && mkdir repo_bak && mv *.repo repo_bak/

wget http://mirrors.aliyun.com/repo/Centos-7.repo 

wget http://mirrors.aliyun.com/repo/epel-7.repo 

yum clean all && yum makecache

CentOS7安装docker（参考官方文档）

官方地址：传送门


yum install -y yum-utils && yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

systemctl start docker  && systemctl enable docker

加速服务

# vim /etc/docker/daemon.json
{
  "data-root": "/data/dockerdata",
  "registry-mirrors": [
    "https://docker.1ms.run",
    "https://docker.1panel.live"
  ],
  "dns": [
    "8.8.8.8",

MySQL备份

常规备份

执行编辑脚本 bash vim /opt/script/mysqlbak.sh 输入如下内容：

#!/bin/bash
bak_date=`date +%Y%m%d`
log_date=`date +'%Y年%m月%d日%k时%M分%S秒'`

mkdir -p /opt/mysql_bak/log /opt/mysql_bak/bak

echo  "$log_date:  开始备份..." >> /opt/mysql_bak/log/mysqlbak.log
echo  "$log_date:  正在生成备份文件.sql..." >> /opt/mysql_bak/log/mysqlbak.log

#全量备份文件生成 
mysqldump -u{用户名} -p{密码} --all-databases > /opt/mysql_bak/bak/mysqlbak.sql
size=`ls -l /opt/mysql_bak/bak/  | grep mysqlbak.sql | awk '{print int($5)}'`
#验证备份文件大小
m_bak_size=100000
m_tar_size=10
if [ "$size" -gt "$m_bak_size" ]; then

        echo  "$log_date:  备份文件生成成功！" >> /opt/mysql_bak/log/mysqlbak.log
        echo  "$log_date:  正在生成打包文件..." >> /opt/mysql_bak/log/mysqlbak.log
        #打包备份文件
        cd  /opt/mysql_bak/bak/
        tar -zcf mysqlbak$bak_date.tar.gz mysqlbak.sql
        tar_size=`ls -l /opt/mysql_bak/bak/ | grep mysqlbak$bak_date.tar.gz | awk '{print int($5)}'`
        #验证打包文件并删除原备份文件
        
        if [ "$tar_size" -gt "$m_tar_size" ]; then
                rm -rf /opt/mysql_bak/bak/mysqlbak.sql
                tar_status='已经完成备份！'
                echo "$log_date:  $tar_status" >> /opt/mysql_bak/log/mysqlbak.log
        else
                tar_status='备份打包失败！'
                echo "$log_date:  $tar_status" >> /opt/mysql_bak/log/mysqlbak.log

else     
         tar_status='备份生成失败！'
        echo "$log_date:  $tar_status" >> /opt/mysql_bak/log/mysqlbak.log
fi

# 删除180天前的备份文件
find /opt/mysql_bak/bak/ -mtime "+180"  -exec rm -f {} \;

利用docker备份

执行编辑脚本 bash vim /opt/script/mysqlbak_docker.sh 输入如下内容：

#!/bin/bash
bak_date=`date +%Y%m%d`
log_date=`date +'%Y年%m月%d日%k时%M分%S秒'`

mkdir -p /opt/mysql_bak/log /opt/mysql_bak/bak

echo  "$log_date:  开始备份..." >> /opt/mysql_bak/log/mysqlbak.log
echo  "$log_date:  正在生成备份文件.sql..." >> /opt/mysql_bak/log/mysqlbak.log

#全量备份文件生成 
docker exec {容器名称或容器ID}  mysqldump -u{用户名} -p{密码} --all-databases > /opt/mysql_bak/bak/mysqlbak.sql
size=`ls -l /opt/mysql_bak/bak/  | grep mysqlbak.sql | awk '{print int($5)}'`
#验证备份文件大小
m_bak_size=100000
m_tar_size=10
if [ "$size" -gt "$m_bak_size" ]; then

        echo  "$log_date:  备份文件生成成功！" >> /opt/mysql_bak/log/mysqlbak.log
        echo  "$log_date:  正在生成打包文件..." >> /opt/mysql_bak/log/mysqlbak.log
        #打包备份文件
        cd  /opt/mysql_bak/bak/
        tar -zcf mysqlbak$bak_date.tar.gz mysqlbak.sql
        tar_size=`ls -l /opt/mysql_bak/bak/ | grep mysqlbak$bak_date.tar.gz | awk '{print int($5)}'`
        #验证打包文件并删除原备份文件
        
        if [ "$tar_size" -gt "$m_tar_size" ]; then
                rm -rf /opt/mysql_bak/bak/mysqlbak.sql
                tar_status='已经完成备份！'
                echo "$log_date:  $tar_status" >> /opt/mysql_bak/log/mysqlbak.log
        else
                tar_status='备份打包失败！'
                echo "$log_date:  $tar_status" >> /opt/mysql_bak/log/mysqlbak.log

SSL证书

申请免费的通配SSL证书

环境

系统：CentOS 7.9
域名：*.example.com

步骤

安装Certbot

安装Snap
Snap
安装Certbot
Certbot文档

申请证书

# 因为申请通配证书需要手动验证，所以需要使用dns-01验证方式
certbot certonly -d "*.xx.com" -d xx.com --manual --preferred-challenges dns-01
# 按照提示进行验证 在dns解析中添加txt记录 
# 在提示信息中给到的类似https://toolbox.googleapps.com/apps/dig/#TXT/的站点验证txt记录后 再进行下一步

# 最后会生成证书 保存目录会在日志中打印出来
# 证书有效期为90天 需要手动续签  同时还有邮件的，非常方便

SpringBoot►Docker

springboot with docker

常用的springboot项目中的Dockerfile示例

Dockerfile：利用容器打包并缓存maven

# 拉取编译环境
FROM maven:3.8.3-openjdk-17 as builder
# 创建项目目录
RUN mkdir /project

# 使用项目配置的文件
COPY settings.xml /usr/share/maven/conf/settings.xml

# 拷贝源码到固定的目录，注意前面有个 '.'
COPY ./pom.xml /project/pom.xml

# 切换到源码目录
WORKDIR /project

# 安装依赖
RUN mvn dependency:go-offline

# 复制源代码
COPY ./src /project/src

# 使用maven进行编译
RUN mvn clean package -Dmaven.test.skip=true

# 拉取运行环境，这个镜像打包出的镜像比较小，如需要可换成oracle的jre
FROM openjdk:17

# 从编译好的镜像中将jar拷贝到运行时容器
COPY --from=builder /project/target/xxxx.jar /

# 容器启动时执行的命令，这里可加jvm参数
ENTRYPOINT ["java","-jar","/xxxx.jar"]

# 开放端口，根据自己的配置进行开放
EXPOSE 8080

配套deploy.sh脚本

#!/bin/bash
start=$(date +%s)
cd /data/java_project_dir #切换到java项目所在目录 
echo "切换目录"
git pull 
echo "更新代码 完成"
docker build . --tag tts 
echo "打包镜像 完成"
docker stop tts
echo "停止服务 完成" 
docker rm tts
echo "删除容器 完成" 
docker run -itd --name=tts -p 28085:8080 tts
echo "启动服务 完成" 
docker image prune -f
echo "删除无tag镜像"
end=$(date +%s)
take=$(( end - start ))
echo 操作完成 本次用时：${take}s

安装dnf命令

正常情况下openjdk:17的镜像中是不带有yum或者dnf命令，如果要用上这个命令那就需要安装一下

启动与openjdk:17 对应相同版本的 oracleLinux (查询镜像内的cat /etc/os-release)
1
docker run -itd --name=oraclelinux85 oraclelinux:8.5

进入容器

1	docker exec -it oraclelinux85 /bin/bash

安装基础包
1
yum -y install yum-utils
下载dnf所有程序包（包括依赖），程序会下载所有文件在当前目录下
1
repotrack dnf
退出容器 oraclelinux85 ，并复制文件到宿主机
1
docker cp oraclelinux85:/root/* ./tmp

复制文件从宿主机到目标容器

1	docker cp ./tmp targetContainer:/root/

进入目标容器安装程序

docker exec -it targetContainer /bin/bah
cd /root/
rpm -Uvh --force --nodeps *.rpm
rm -rf *.rpm

最后，愉快的使用dnf命令吧
