构建自己的mysql镜像

##MYSQL的Dockerfile##
将mysql-boost-5.7.20.tar.gz这个包拖进mysql/下
[root@docker mysql]# vim Dockerfile
FROM centos:7
MAINTAINER ZZT
ADD mysql-boost-5.7.20.tar.gz /opt
ADD run.sh /opt
WORKDIR /opt
RUN chmod +x run.sh
RUN ./run.sh
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
WORKDIR /usr/local/mysql/
RUN bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
##这里遇到个坑，start不起来，所以我使用开机自启最后交给容器帮我启动
RUN cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
EXPOSE 3306
RUN echo -e "#!/bin/bash \n systemctl enable mysqld" > /1.sh
RUN chmod 755 /1.sh
RUN sh /1.sh
##这里初始化，将mysql启动起来，对应前面的enable
CMD ["init"]
[root@docker mysql]# docker build -t mysql:new .
==================================================
###privileged表示root账户访问容器不降权，如果不加进不去mysql###
[root@docker mysql]# docker run -d -P --name=mysql_root --privileged mysql:new
[root@docker ~]# docker ps -a
