阿里云CentOS6Web服务器配置

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。

1. jdk
2. Tomcat
3. Maven
4. Git
5. 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

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

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

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

官方下载地址

http://www.oracle.com/technetwork/java/javase/archive-139210.html

使用wget命令下载JDk

3.重命名JDK

mv 原文件名 新文件名 这里要用空格分开

sudo mv jdk-7u80-linux-x64.rpm\?AuthParam\=1502245631_f04b3399ba732d3836923a1103166a05  jdk-7u80-linux-x64.rpm

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

sudo rpm -ivh 文件

sudo rpm -ivh jdk-7u80-linux-x64.rpm

6.配置环境变量

sudo vim /etc/profile

编辑配置文件

修改完成后wq！强制保存退出

生效配置文件

source /etc/profile

2.解压Tomcat

tar -zxvf 解压文件

sudo tar -zxvf apache-tomcat-7.0.79.tar.gz

3.将解压好的Tomcat文件放到/usr/local文件夹下

sudo mv apache-tomcat-7.0.79 /usr/local/

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

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.
