#开发
#启动 Run steps: 0. cd accounts
- npm install //install node modules
- npm start //start nodejs server command
or 3. $ [sudo] npm install forever -g forever start ./bin/www forever stop ./bin/www
文件定义: app.js define routes
安装nodejs链接mongodb的driver(在express没有mongodb的情况下): 1.npm install mongodb --save 2.npm install bson --save
//Data level 创建mogodb: 0. cd ~/mongodb-osx-x86_64-3.2.4
- cd bin
- mkdir -p data/db
- mkdir log/
- touch dbName
启动mongodb(本地): 4. ./mongod --dbpath=../data/db/ --logpath ../log/dbName --fork
测试启动是否正常: 5. ./mongo 6. use dbName 7. db.users.save({name:'121212',password:123456}) 8. 27017 9. db.users.find() // show collections 查看所有集合

root@instance-tbbjrcnc:/# touch ?/var/run/mongodb/mongod.pid root@instance-tbbjrcnc:/# chown -R mongodb:mongodb /var/run/mongodb/mongod.pid 即可启动成功。
1.找到mongod.lock文件，并删除mongod.lock
2.以修复方式启动mongodb
/usr/bin/mongod -f /etc/mongod.conf --repair
rm -rf /var/lib/mongo/mongod.lock

/usr/local/mongodb/bin/mongod -f /opt/config/mongod.conf
问题描述：（mongod和s也有同样的情况） /usr/bin/mongod -f /etc/mongoc.conf about to fork child process, waiting until server is ready for connections. forked process: 911 ERROR: child process failed, exited with error number 1
查看mongoc日志如下： ERROR: Cannot write pid file to /var/run/mongodb/mongoc.pid: No such file or directory
日志说的很明白了，无法写入pid文件到/var/run/mongodb/mongoc.pid下。
查看/var/run/下面会发现没有mongodb目录，所以建一个mongodb目录就可以了，启动的时候会自动在这个目录下生成pid文件。
然后再启动：
/usr/local/mongodb/bin/mongod -f /opt/config/mongod .conf http://118.24.221.219:3000/#h5/view/incomes_lis

先通过shell连上服务器： mongo use admin db.shutdownServer()
