安装mysql5.7

1) 下载rpm安装包

wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
2) 安装mysql源
yum localinstall mysql57-community-release-el7-8.noarch.rpm
3）检查mysql源是否安装成功
yum repolist enabled | grep "mysql.-community."
4）开始安装mysql
yum install mysql-community-server
yum install mysql-community-devel
5) 启动mysql
service mysqld start
6)查看mysql启动状态
service mysqld status
7）设置开机启动
systemctl enable mysqld
systemctl daemon-reload
8）获取mysql默认生成的密码
grep ‘temporary password‘ /var/log/mysqld.log
进入mysql命令行
nysql -uroot -p
更换密码
ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘123IsYourNewPassword!‘;

安装docker

首先查看内核版本：uname -r
命令安装docker:

yum -y install docker-io

启动docker

service docker start
设置开机启动
chkconfig --add --level 245 docker
service docker status

如果出现docker dead but subsys locked执行
　　rm /var/run/docker.
　　rm /var/lock/subsys/docker
　　rm -rf /var/lib/docker/
rpm手动下载安装docker

yum install https://get.docker.com/rpm/1.7.1/centos-6/RPMS/x86_64/docker-engine-1.7.1-1.el6.x86_64.rpm

docker镜像加速（用的网易蜂巢）

　　 $ sudo echo "DOCKER_OPTS="$DOCKER_OPTS --registry-mirror=http://hub-mirror.c.163.com"" >> /etc/default/docker
　　 $ service docker restart
