安装node.js

yum -y update

1.curl -sL https://rpm.nodesource.com/setup_10.x | bash -
2.yum install -y nodejs
3.npm install pm2 -g

安装git

yum install -y git

本地生成ssh拉取代码

1.ssh-keygen -t rsa -C "2331396362@qq.com" 
2.三次回车直接使用默认值
3.cd ~/.ssh
4.cat  id_rsa.pub 复制内容到gitee上

部署项目

1.在项目的package.json中script加入 "pm2": "pm2 start npm --name 'pc_hhb' -- run start" //写自己的项目名字

2.npm run pm2 

3.pm2 save //保存列表防止重启后node服务丢失

4.pm2 satrtup //pm2加入开机自启动

修改hosts

1.vi /etc/hosts 写入对应的接口地址，保存退出
2./etc/init.d/network restart //重新读取配置

nginx方面值得注意的地方

• 1.查看服务器允许的最大连接数

ulimit -a 查看open files 一般是65535

• 2.查看cpu核

cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l cpu个数
cat /proc/cpuinfo| grep "processor"| wc -l cpu核数

• 2.nginx.conf配置

user root;
worker_processes  4; ##与cpu的核数一致 如果不写可以使用 auto
events {
    worker_connections  16300; ##这个值是根据 (65535/4)取整数出来的
    multi_accept on;  ## events区域下accept_mutex参数将使每个可用的worker进程逐个接受新连接
    accept_mutex_delay 500ms; ## 尝试获取互斥锁并开始接受新的连接
    accept_mutex on;   ##连接放到监听队列中,不开启则一条一条监听
