腾讯云服务器安装java服务部署环境

一、安装Java

1.查看镜像中带有的java安装版本

yum -y list java*

2.安装已有的版本

yum install java-1.8.0-openjdk.i686

二、安装mysql

1.检测是否已安装mysql，一下任意一条都可检测

rpm -qa|grep mysql*
rpm -qa|grep -i mysql
yum list installed mysql*

2.下载mysql8

mysql8使用wget命令下载安装会报错，所以需要再官网下载的，需要注意版本

解压安装包

[root@VM_0_13_centos mysql]# rpm -ivh mysql80-community-release-el7-3.noarch.rpm 

安装

只要有输入全选择y

[root@VM_0_13_centos mysql]# yum install mysql-community-server

启动

[root@VM_0_13_centos mysql]# grep "password" /var/log/mysqld.log

修改密码

# 查看默认密码
[root@VM_0_13_centos mysql]# grep "password" /var/log/mysqld.log

# 登录后修改
mysql> set global validate_password.policy=LOW;
mysql> set password='12345';

创建用户

# 进入mysql数据库
create user username@'%' identified by 'password';
# 设置远程登录权限
grant all privileges on *.* to devuser@'%' with grant option;

yum install nginx
