一文搞定linux N个服务的搭建

搭建开发测试环境非常麻烦，公司的开发测试服务器中毒做数据恢复，顺带整理下搭建的方式。

本人是程序员，linux系统知识比较薄弱，故系统的安全方面本文未涉及，请酌情做安全策略。

本来是内网服务器，用frp暴露到了公网，导致被挖矿。。感觉frp还是不安全，现在只能在需要穿透的
时候开下，其他时候关闭。

SpringBoot整合jwt和mybatis-plus的脚手架项目

基本配置

安装基本命令

有些命令可能未默认安装，如果发现命令无法使用，再通过下面的方式进行安装。

安装ifconfig

centos 7中自带的查看网络的命令是: ip addr

如果还是想要 ifconfig

安装net-tools

yum install net-tools

安装vim

yum install vim

网络配置

如果是虚拟机模式，VM box的网络模式修改为 桥接。

修改hostname

修改ip地址

命令为：

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s3

修改为如下即可，然后重启网卡service network restart：

TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static"                   ###修改为static模式才能配置ip，默认是dhcp模式
IPADDR="192.168.1.254"               ###网卡IP地址
BROADCAST-"192.168.1.255"            ###子网广播地址
GATEWAY="192.168.1.1"                 ###网关地址
NETMASK="255.255.255.0"                 ###网卡对应网络掩码
DNS1="192.168.1.1"                     ###DNS地址
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="enp0s3"
UUID="226a0768-3a2f-4485-9694-d8fea85694ad"
DEVICE="enp0s3"
ONBOOT="yes"            #系统启动时是否设置此网络接口，设置为yes时，系统启动时激活此设备。默认设置为yes。

修改dns

1） vi /etc/resolv.conf
[root@localhost ~]# vi /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.1.1        #本机的网关地址（路由器的地址），在ip配置的时候有指定
nameserver 114.114.114.114    #其他dns
naemserver 1.1.1.1

search localdomain
3）确保可用DNS解析

[root@localhost Desktop]# grep hosts /etc/nsswitch.conf

配置更新源

配置更新源为阿里源

新建sourceSet.sh文件，贴上如下代码执行即可：

chmod 775 sourceSet.sh 
#!/bin/bash

开发环境

JDK

下载jdk

最新jdk1.8.0_211我已经上传到网盘：

链接：https://pan.baidu.com/s/1B9DR...
提取码：5e92 复制这段内容后打开百度网盘手机App，操作更方便哦)

上传和解压到该路径：
/usr/local/base/jdk1.8.0_211

设置环境变量：

vi /etc/profile
在最后添加如下内容：

#java environment
export JAVA_HOME=/data/jdk1.8.0_211
export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar
export PATH=$PATH:${JAVA_HOME}/bin
重新加载环境变量：
[root@izwz9hy3mj62nle7573jv5z jdk1.8.0_181]# source /etc/profile
[root@izwz9hy3mj62nle7573jv5z jdk1.8.0_181]# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
卸载jdk：

如果需要卸载，那么删除环境变量和jdk解压后的目录即可。

安装服务

nginx

添加源

# rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

安装

yum install -y nginx

查看安装后的目录

# whereis nginx
nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz /usr/share/man/man3/nginx.3pm.gz
  • Nginx配置路径：/etc/nginx/
  • 执行程序路径：/usr/sbin/nginx
  • PID目录：/var/run/nginx.pid
  • 错误日志：/var/log/nginx/error.log
  • 访问日志：/var/log/nginx/access.log
  • 默认站点目录：/usr/share/nginx/html

需要主要的是配置路径和执行程序路径。

启停命令

#启动
[root@nginx]#/usr/sbin/nginx -c /etc/nginx/nginx.conf
#检测配置
[root@nginx]#/usr/sbin/nginx -c /etc/nginx/nginx.conf -t
#重启
[root@nginx]# /usr/sbin/nginx -s reload
[root@nginx]# /usr/sbin/nginx -c /etc/nginx/nginx.conf -s reload

测试

如果显示表示成功

[root@zhirui-base nginx]# curl localhost:80
