COMCAT_HOME=/usr/share/tomcat
export JAVA_HOME PATH CLASSPATH COMCAT_BASE COMCAT_HOME
source /etc/profile
systemctl start tomcat.service
systemctl status tomcat
​
systemctl status firewalld
​
#执行命令来开启8080端口
firewall-cmd --permanent --zone=public --add-port=8080/tcp
​
#重启防火墙
firewall-cmd --reload
​
#验证开启的8080端口是否生效
firewall-cmd --zone=public --query-port=8080/tcp
解决FirewallD警告问题
vi /etc/firewalld/firewalld.conf

yum -y install ./mysql80-community-release-el7.rpm
​
#生成yum索引缓存并查看目录大小
yum makecache fast
​
#查看正在使用的MySQL repo
yum repolist all|grep mysql
​
#安装MySQL8.0

use mysql;
#备注Mysql5.7+ password字段 已改成 authentication_string字段
update user set authentication_string='' where user='root';
​
#重置成新密码
#备注Mysql8.0修改密码方式已有变化此处是个坑需要注意
​
#Mysql8.0之前;
update user set password=password('root') where user='root';
#Mysql8.0之后
alter user 'root'@'localhost' identified by 'root';
​
#显示密码策略
SHOW VARIABLES LIKE 'validate_password%';
#校验密码不能等同于用户名
set global validate_password.check_user_name=OFF;
#设置最低长度为4
set global validate_password.length=4;
#校验设置低级别策略
set global validate_password.policy=LOW;
​
#显示密码策略
SHOW VARIABLES LIKE 'validate_password%';
​
​
#设置完密码策略后重新输入修改命令更改后的密码为123456
alter user 'root'@'localhost' identified by '123456';
​
#退出命令行
mysql> quit;
Bye

​
八、docker开机启动
​
[root@localhost ~]# systemctl enable docker
​
九、修改镜像默认存储路径
​
