最近买了阿里云的CentOS系统的Linux服务器，花了些时间把环境配置了一下，用来发布后端。
- jdk
- Tomcat
- Maven
- Git
- mysql5.7.17
CentOS环境初始化
1.CentOS备份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2.下载新的CentOS-Base.repo
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
3.生成缓存
yum makecache
阿里云Centos环境初始化
http://mirrors.aliyun.com/help/centos
创建新用户
1. 创建用户
useradd -d /usr/用户名 -m 用户名
2.设置用户密码
passwd 用户名
设置新用户密码
![创建新用户命令截图]()
3.修改配置文件
vim /etc/sudoers
找到root后添加一条新用户的信息 ALL=(ALL) ALL意思是 用户=可以以root权限执行的命令 添加完成后 wq! 强制保存退出
![修改配置文件截图]()
到这里新用户的配置就结束了。
用新用户登录后注意要使用 “sudo”命令
创建安装包存放文件夹
用mkdir命令创建用来存放安装包的文件夹
mkdir developer
注意不是root用户要用sudo
sudo mkdir developer
配置JDk
1.检查是否安装JDk
rpm -qa| grep jdk
使用这条命令检查是否安装jdk
2.下载JDk

4.赋权
chmod 777 赋权对象，让所有用户都能使用JDK
sudo chmod 777 apache-tomcat-7.0.79.tar.gz
5.安装JDK

3.启动mysql 重启linux服务器
sudo shutdown -r now
启动数据库
service mysqld start
数据库初始化
1.初始化数据库
sudo mysql_secure_installation
mysql5.7.17加强了安全系统，需要去/var/log/mysqld.log下找到初始密码
vim /var/log/mysqld.log
收索 A temporary password is generated for root@localhost ![mysql初始密码]()
Securing the MySQL server deployment.
Enter password for user root: <–输入找到的初始密码
he existing password for the user account root has expired. Please set a new password.
New password: <– 设置root用户的密码
Re-enter new password: <– 再输入一次你设置的密码
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration
of the plugin.
Using existing password for root.
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : <-是否更改root密码
New password:<– 再输入一次你设置的密码
Re-enter new password: <– 再输入一次你设置的密码
Estimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : <-确认更改root密码
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : <-删除匿名用户?
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : <–是否禁止root远程登录,根据自己的需求选择Y/n并回车,建议禁止
... skipping.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : <– 是否删除test数据库,直接回车
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : <– 是否重新加载权限表，直接回车
Success.
All done!
3.登录数据库
mysql -uroot -p
3.创建用户
CREATE USER '用户名'@'地址' IDENTIFIED BY '密码';
4.创建数据库
create database `数据库` default character set utf8 collate utf8_general_ci;
5.赋权
grant all privileges on 数据库.* to 用户名@localhost identified by '密码';
6.进入数据库
use 数据库
7.还原表
source 备份文件地址
8.设置开机启动
sudo chkconfig mysqld on
到这里服务器的配置就结束了
修改完成后wq！强制保存退出
