linux命令

安裝mysql5.7

1) 下載rpm安裝包

wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
2) 安裝mysql源
yum localinstall mysql57-community-release-el7-8.noarch.rpm
3）檢查mysql源是否安裝成功
yum repolist enabled | grep "mysql.-community."
4）開始安裝mysql
yum install mysql-community-server
yum install mysql-community-devel
5) 啓動mysql
service mysqld start
6)查看mysql啓動狀態
service mysqld status
7）設置開機啓動
systemctl enable mysqld
systemctl daemon-reload
8）獲取mysql默認生成的密碼
grep 'temporary password' /var/log/mysqld.log
進入mysql命令行
nysql -uroot -p
更換密碼
ALTER USER 'root'@'localhost' IDENTIFIED BY '123IsYourNewPassword!';

安裝docker

首先查看內核版本：uname -r
命令安裝docker:

yum -y install docker-io

啓動docker

service docker start
設置開機啓動
chkconfig --add --level 245 docker
service docker status

如果出現docker dead but subsys locked執行
　　rm /var/run/docker.
　　rm /var/lock/subsys/docker
　　rm -rf /var/lib/docker/
rpm手動下載安裝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鏡像加速（用的網易蜂巢）

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