  -a, --append     Append logs
  -f, --fifo       Stream logs to stdout
  -n, --number     Number of log lines to print
  --pidFile        The pid file
  --uid            Process uid, useful as a namespace for processes (must wrap in a string)
                   e.g. forever start --uid "production" app.js
                       forever stop production

  --watchDirectory Top-level directory to watch from
  --watchIgnore    To ignore pattern when watch is enabled (multiple option is allowed)
  --killSignal     Support exit signal customization (default is SIGKILL)
                   used for restarting script gracefully e.g. --killSignal=SIGTERM
  -h, --help       You're staring at it

[Long Running Process]
  The forever process will continue to run outputting log messages to the console.
  ex. forever -o out.log -e err.log my-script.js

[Daemon]
  The forever process will run as a daemon which will make the target process start
  in the background. This is extremely useful for remote starting simple node.js scripts
  without using nohup. It is recommended to run start with -o -l, & -e.
  ex. forever start -l forever.log -o out.log -e err.log my-daemon.js
      forever stop my-daemon.js

启动脚本范例

通过forever或脚本来管理站点服务的启动和停止，并设置服务自启动；
日志统一输出至/var/log/，设置日志回滚；
避免重复启动。
以下待完成：
- 使用非root用户启动nodejs，降低安全风险

使用方法

将公共启动脚本放到/usr/local/bin目录中

cp nodejs_startup.sh /usr/local/bin/
chmod 755 /usr/local/bin/nodejs_startup.sh

编辑nodejs_startup.sh设置环境参数

LOGDIR=/var/log/           #统一日志目录
NODEJS=/usr/local/nodejs   #nodejs路径
#NODEJS=/opt/nodejs

#启动环境参数
#export NODE_ENV=development
#export NODE_ENV=production
export NODE_ENV=testing
export brand=foton

放置项目工程文件到/opt/

# 将App放到/opt/目录下，如：/opt/myportal
cp -R myportal /opt/

设置启动脚本及开机自启动

# 创建启动脚本软链接，使用nodejs-AppName命名(其中AppName为/opt/下的目录名称)，如：
cd /etc/init.d && ln -sfT /usr/local/bin/nodejs_startup.sh nodejs-myportal

# 设置开机自启动
chkconfig --add nodejs-myportal

# 服务进程管理
/etc/init.d/nodejs-myportal {start|stop|restart|list|logs|status}

设置日志自动回滚

cat > /etc/logrotate.d/nodejs <<EOF
/var/log/tima/nodejs_*.log {
    copytruncate
    weekly
    rotate 20
    compress
    missingok
    size 100M
}

项目构建

grunt: 基于任务的命令行构建工具。类似Java业界的Ant工具一样。
- http://www.gruntjs.net/
Bower: 管理bootstrap、JQuery、CSS等前端框架
- http://bower.io/

环境配置

# 安装nodejs
# 设置npm镜像地址
npm config set registry http://registry.cnpmjs.org
# 安装基于任务的命令行构建工具
npm install -g grunt-cli
npm install -g bower

项目构建

# 从git仓库clone源代码，进入项目目录下，运行：
npm install    # 自动下载相对应的Grunt插件
bower install  # 安装依赖
grunt package

国内npm镜像

通过config命令

npm config set registry https://registry.npm.taobao.org 
npm info underscore #（如果上面配置正确这个命令会有字符串response）

命令行指定

npm --registry https://registry.npm.taobao.org info underscore

编辑 ~/.npmrc 加入下面内容

registry = https://registry.npm.taobao.org
