第1章 安装依赖环境
node和npm有版本要求的，数据库MongoDB的安装自己百度
[root@jhkj177 ~]# node -v
v6.14.0
[root@jhkj177 ~]# npm -v
3.10.10
npm install -g yapi-cli --registry https://registry.npm.taobao.org
报错：
[root@jhkj177 ~]# yapi server
/usr/lib/node_modules/yapi-cli/src/commands/import.js:16

^^^^^^^^

网上搜报错没找到什么解决方法，然后去官网看了一下，发现官方要求的node版本在7.6以上，于是怀疑是不是node版本太低的问题，换了符合官方要求版本的node后：
[root@jhkj66 home]# npm install -g yapi-cli --registry https://registry.npm.taobao.org
/server/tools/node-v8.11.4-linux-x64/bin/yapi -> /server/tools/node-v8.11.4-linux-x64/lib/node_modules/yapi-cli/bin/yapi-cli
/server/tools/node-v8.11.4-linux-x64/bin/yapi-cli -> /server/tools/node-v8.11.4-linux-x64/lib/node_modules/yapi-cli/bin/yapi-cli
+ yapi-cli@1.2.8
added 266 packages in 7.322s
[root@jhkj66 home]# yapi server
-bash: yapi: 未找到命令
找不到命令这个报错要看上一条命令中yapi的位置，他都会告诉你的进去以后执行命令：
[root@jhkj66 bin]# ./yapi server
在浏览器打开http://0.0.0.0:9090 访问。非本地服务器，请将0.0.0.0 替换成指定的域名或ip
在浏览器中进入安装页面
1.1报错：
查看yapi目录属主是不是root，
[root@jhkj66 node-v8.11.4-linux-x64]# chown -R root.root /server/tools/node-v8.11.4-linux-x64
删除init.lock，
清空数据库
[admin@jhkj66 mongodb]$ ./bin/mongo

Server has startup warnings:

switched to db yapi
> db.dropDatabase()

1.2重新部署：
成功！
log: mongodb load success...
初始化管理员账号成功,账号名："admin@admin.com"，密码："ymfe.org"
部署成功，请切换到部署目录，输入："node vendors/server/app.js" 指令启动服务器, 然后在浏览器打开http://127.0.0.1:3000 访问
1.1启动yapi：
安装的目录下面会有vendors目录，进入执行一下命令启动
[root@jhkj66 vendors]# node server/app.js
log: the server is start at 127.0.0.1:3000
log: mongodb load success...
浏览器访问：
安装pm2，来管理node项目，让yapi变成守护进程
[root@jhkj66 vendors]# npm install -g pm2

+ pm2@3.0.4

现在执行启动命令会提示找不到pm2，是因为没有做软连接
[root@jhkj66 bin]# ln -s /server/tools/node-v8.11.4-linux-x64/bin/pm2 /usr/bin/
[root@jhkj66 vendors]# pm2 start server/app.js
