详解docker 制作mysql镜像并自动安装脚本

#docker自动安装mysql
echo -e "\033[32m '>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 默认安装参数： >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>' \033[0m"
echo -e "\033[32m '端口：3309' \033[0m"
echo -e "\033[32m '映射宿主机路径： /mysql' \033[0m"
echo -e "\033[32m '密码：xxxxxx' \033[0m"
echo -e "\033[32m '容器名称：mysql8' \033[0m"
echo -e "\033[32m '开启binlog' \033[0m"
echo -e "\033[32m '设置连接数1k' \033[0m"
echo -e "\033[32m '设置连接超时断开24h' \033[0m"
echo -e "\033[32m '设置使用4个cpu核心' \033[0m"
mkdir -p /mysql
### 1下载镜像
docker pull mysql
if [ $? -eq 0 ]
    then 
        echo -e "\033[32m '>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 1下载镜像 finish >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>' \033[0m"
    else 
        echo -e "\033[31m '__________________________________  1下载镜像 bad ,and EXIT' \033[0m"
        exit 1
fi

### 创建 dockerfile
rm -rf ./mymysql.yaml
echo '### dockerfile 自定义mysql容器镜像' >> ./mymysql.yaml
echo 'FROM mysql:latest' >> ./mymysql.yaml
echo '#使用官方mysql镜像最新版' >> ./mymysql.yaml
echo '' >> ./mymysql.yaml
echo 'RUN echo "###" >> /etc/mysql/my.cnf' >> ./mymysql.yaml
echo '' >> ./mymysql.yaml
echo 'RUN echo "log_bin = 1" >> /etc/mysql/my.cnf' >> ./mymysql.yaml
echo '#开启binlog日志,存储在默认位置' >> ./mymysql.yaml
echo '' >> ./mymysql.yaml
echo 'RUN echo "max_connections = 1050" >> /etc/mysql/my.cnf' >> ./mymysql.yaml
echo 'RUN echo "mysqlx_max_connections = 1000" >> /etc/mysql/my.cnf' >> ./mymysql.yaml
echo '#最大连接数' >> ./mymysql.yaml
echo '' >> ./mymysql.yaml
echo 'RUN echo "wait_timeout=86400" >> /etc/mysql/my.cnf' >> ./mymysql.yaml
echo 'RUN echo "interactive_timeout=86400" >> /etc/mysql/my.cnf' >> ./mymysql.yaml
echo '#空闲断开时长，秒' >> ./mymysql.yaml
echo '' >> ./mymysql.yaml
echo 'RUN echo "innodb_read_io_threads=4" >> /etc/mysql/my.cnf' >> ./mymysql.yaml
echo 'RUN echo "innodb_write_io_threads=4" >> /etc/mysql/my.cnf' >> ./mymysql.yaml
echo '#设置使用多核cpu，默认使用4核，根据cpu核心数设置' >> ./mymysql.yaml
###______________________________________________________________________________________________________
###使用mymysql.yaml构建镜像mymysql:1
docker build -f ./mymysql.yaml -t "mymysql:1" .
if [ $? -eq 0 ]
    then 
        echo -e "\033[32m '>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> mymysql:1 镜像构建成功 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>' \033[0m"
    else 
        echo -e "\033[31m '__________________________________  mymysql:1 镜像构建失败,and EXIT' \033[0m"
        exit 1
fi
### 2创建容器
docker create -p 3309:3306 --restart=always --name mysql8 -v /mysql/mysql_08/log:/var/log/mysql -v /mysql/mysql_08/data:/var/lib/mysql -v /etc/localtime:/etc/localtime -e MYSQL_ROOT_PASSWord=xxxxx -it  mymysql:1
if [ $? -eq 0 ]
    then 
        echo -e "\033[32m '>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>  2创建容器 finish >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>' \033[0m"
    else 
        echo -e "\033[31m '__________________________________  2创建容器 bad ,and EXIT' \033[0m"
        exit 1
fi
### 3启动容器
docker start mysql8
if [ $? -eq 0 ]
    then 
        echo -e "\033[32m '>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 3启动容器 finish >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>' \033[0m"
    else 
        echo -e "\033[31m '__________________________________  3启动容器 bad ,and EXIT' \033[0m"
        exit 1
fi
### 显示容器状态
echo -e "\033[32m '>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 显示已运行容器：' \033[0m"
docker ps
