请先安装好jdk1.8

1. 安装mysql5.7

   安装方法

---

2. 安装nginx

• 程序安装 sudo apt-get install nginx
  安装后可执行文件路径/usr/sbin/nginx 此时在任意路径下输入nginx都可以启动
  查看nginx是否在执行 ps -ef|grep nginx
• nginx命令

nginx -s stop 停止运行
nginx -s reload 重新加载配置文件,慎用，有概率不生效，建议老老实实重启

• 配置文件更改，ubuntu下的配置文件有两个路径
  /etc/nginx/nginx.conf 文件内容如下

---

worker_processes auto;
pid /run/nginx.pid;events {worker_connections 768;# multi_accept on;

#	}
# 
#	server {
#		listen     localhost:143;
#		protocol   imap;
#		proxy      on;
#	}
#}

---

/etc/nginx/sites-available/default 文件内容如下,已更改
作用为:监听本地1111端口,并将请求转发到cluster上，cluster配置了3个地址，实现负载均衡

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

3. nacos 安装，我使用的是nacos 1.1.4，版本不同对下面的步骤有影响，尤其是startup.sh

• nacos github下载
• 可以在ubuntu中使用wget 下载地址 下载
• 加压下载后的gz压缩包 tar -zxvf 文件名 默认加压到当前文件夹，可以使用**-C 路径**指定解压目录
• 进入解压得到的nacos文件夹cd nacos
• 进入配置文件目录cd conf
• 编辑application.properties文件 在文件最后新增

##############mysqlspring.datasource.platform=mysqldb.num=1
db.url.0=jdbc:mysql://localhost:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=数据库用户名
db.password=数据库密码

• 编写cluster.conf配置文件

#当前目录还是conf
cp cluster.conf.example cluster.conf
#查询ubuntu本机ip，内网外网都可以
ifconfig
#编辑cluster.conf文件，将里面的ip和端口换成自己的，比如我的是,和nginx中配置的端口号#一致
#it is ip
#example
192.168.88.130:3333
192.168.88.130:4444
192.168.88.130:5555

• 更改startup.sh文件，在nacos/bin目录下
  备份startup.sh文件

cp startup.sh startup.sh.back

编辑startup.sh文件,以下是我修改后的
增加-p参数设置属性，用于设置nacos运行端口号

• 启动nacos集群

#在bin目录下，启动三个服务，内存占用较大，可以更改startup.sh中的JAVA_OPT属性减少内
#存分配,下面三条语句请隔2分钟分别执行，如果你的ubuntu配置牛逼当我没说
bash startup.sh -p 3333
bash startup.sh -p 4444
bash startup.sh -p 5555

启动成功的输出

nacos is starting with cluster
nacos is starting，you can check the /home/tom/app/mynacos/nacos/logs/start.out

验证，执行下面的语句输出3说明三台nacos都启动成功

ps -ef|grep nacos|grep -v grep|wc -l

4. 防火墙设置

• 查看防火墙当前状态

sudo ufw status

• 开启防火墙

sudo ufw enable

• 关闭防火墙

sudo ufw disable

• 查看防火墙版本

sudo ufw version

• 默认允许外部访问本机

sudo ufw default allow

• 默认拒绝外部访问主机

sudo ufw default deny

• 允许外部访问53端口

sudo ufw allow 53

• 拒绝外部访问53端口

sudo ufw deny 53

• 允许某个IP地址访问本机所有端口

sudo ufw allow from 192.168.0.1

以上是ubuntu配置nacos的步骤，配置过程中的小问题还需自己解决。
