docker msyql redis 容器创建以及备份

mysql

1. docker pull mysql:8.0.17

2. 	docker run \
   	-p 3307:3306 \
   	--name mysql \
   	--restart always \
   	-v /var/docker/mysql/data/:/var/lib/mysql \
   	-v /var/docker/mysql/conf/:/etc/mysql/conf.d \
   	-v /var/docker/mysql/init/:/docker-entrypoint-initdb.d \
   	-e MYSQL_ROOT_PASSWORD=xx \
   	-d mysql:8.0.17
   

   其它参数
   -e MYSQL_USER=”fengwei”：添加用户fengwei
   -e MYSQL_PASSWORD=”pwd123”：设置fengwei的密码伟pwd123
   -e MYSQL_ROOT_PASSWORD=”rootpwd123”：设置root的密码伟rootpwd123
   –character-set-server=utf8：设置字符集为utf8
   –collation-server=utf8_general_ci：设置字符比较规则为utf8_general_ci

3. 进入容器实例： docker exec -it mysql bash

4. 支持远程连接数据库

      	mysql -uroot -pxx
      	ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'xx';
      	flush privileges;
   

docker run -p 3307:3306 --name mysql --restart always -v D:/docker/mysql/data/:/var/lib/mysql -v D:/docker/mysql/init/:/docker-entrypoint-initdb.d -v D:/docker/mysql/my.cnf:/etc/my.cnf -e MYSQL_ROOT_PASSWORD=hztc12345 -d mysql:8.0.17 --default-authentication-plugin=mysql_native_password

5. 定时备份

    ```
    source /etc/profile
    . ~/.bash_profile
    #!/bin/bash
    
    DATABASE=wechat #database name
    DB_USER=root #database username
    DB_PASS="xx" #database password
    BACKUP=/var/docker/backups/mysql/ #backup path
    DATE=`date +%Y%m%d%H%M` 
    
    # 判断目录是不是已经存在，如果不存在则创建
    if [ ! -d ${BACKUP} ]; then
      mkdir -p ${BACKUP}
    fi
    
    docker exec -i mysql mysqldump -u$DB_USER -p$DB_PASS -h 127.0.0.1 -R --opt $DATABASE |gzip > ${BACKUP}\/${DATABASE}_${DATE}.sql.gz
     
    #just backup the latest 5 days 
    #测试：find /data/bak/mysqldata -name "ei_*.sql.gz" -type f -mtime +5 -exec rm {} \; > /dev/null 2>&1
    find ${BACKUP} -name "${DATABASE}_*.sql.gz" -type f -mtime +5 -exec rm {} \; > /dev/null 2>&1
    
    ```
   

docker exec -i mysql 记住一定不能加 “t”， 否则定时器执行不成功

• 测试脚本 ： sh /shell/docker_mysql_bak.sh
• 添加可执行权限：chmod u+x /shell/docker_mysql_bak.sh
• 查看权限 ls -l /shell/docker_mysql_bak.sh
• 设置定时任务
  添加任务： crontab -e

   00 03 * * * /shell/docker_mysql_bak.sh
  

  查看任务：crontab -l

mysql自动执行sql

docker 连接 redis

1. docker pull redis:5.0.5

2. docker run \
   -p 6380:6379 \
   --name redis \
   -v /var/docker/redis/data:/data \
   -v /var/docker/redis/conf/redis.conf:/etc/redis/redis.conf \
   -d redis:5.0.5 redis-server /etc/redis/redis.conf \
   --appendonly yes
   

   • 添加对外端口-p 6380:6379 外面不需密码就可访问， 去掉不能访问6379端口

spring boot 构建镜像

1. 一个镜像运行两个容器实例

   docker run \
   --name wechat8001 \
   -p 8001:8001 \
   --link mysql:mysql \
   --link redis:redis \
   -d registry.cn-beijing.aliyuncs.com/sunxin/wechat:1.0.1
   
   docker run \
   --name wechat8002 \
   -p 8002:8001 \
   --link mysql:mysql \
   --link redis:redis \
   -d registry.cn-beijing.aliyuncs.com/sunxin/wechat:1.0.1
   

nginx

1. docker pull nginx:1.17.3

2. 用命令：cat /etc/nginx/nginx.conf 查看nginx.conf文件内容然后拷贝出来
   用命令：cat /etc/nginx/conf.d/default.conf 查看default.conf文件内容然后拷贝出来

   mkdir -p /var/docker/nginx/conf / 
   mkdir -p /var/docker/nginx/conf.d /
   mkdir -p /var/docker/nginx/html /
   mkdir -p /var/docker/nginx/logs
   
   
    docker run \
    --name nginx \
    -p 8000:80 \
    -v /var/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
    -v /var/docker/nginx/conf.d:/etc/nginx/conf.d \
    -v /var/docker/nginx/logs:/var/log/nginx \
    -v /var/docker/nginx/html:/usr/share/nginx/html \
    --link wechat8001:wechat8001 \
    --link wechat8002:wechat8002 \
    nginx:1.17.3
   

   安全证书

    docker run \
    --name nginx \
    -p 8000:80 \
    -p 8443:443 \
    -v /var/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
    -v /var/docker/nginx/cert:/etc/nginx/cert \
    -v /var/docker/nginx/conf.d:/etc/nginx/conf.d \
    -v /var/docker/nginx/logs:/var/log/nginx \
    -v /var/docker/nginx/html:/usr/share/nginx/html \
    --link wechat8001:wechat8001 \
    --link wechat8002:wechat8002 \
    nginx:1.17.3
   

   nginx中不要使用下划线命名
