pm2 自定义log, pid 等日志文件位置

方法一:

Log configuration

CLI

Example:

$ pm2 start echo.js --merge-logs --log-date-format="YYYY-MM-DD HH:mm Z"

Options:

--merge-logs                 do not postfix log file with process id--log-date-format <format>   prefix logs with formated timestamp-l --log [path]              specify entire log file (error and out are both included)-o --output <path>           specify out log file-e --error <path>            specify error log file

JSON way

 {  "script"          : "echo.js",  "error_file"      : "err.log",  "out_file"        : "out.log",  "merge_logs"      : true,  "log_date_format" : "YYYY-MM-DD HH:mm Z"}

Combine out and err logs

To combine all logs into the same file set the same value for error_file, out_file or use an additional log_file.

For example, this keeps out and err separated but adds a combined file:

{  "log_file": "combined.outerr.log",  "out_file": "out.log",  "err_file": "err.log"}

Or if you want out and err combined without any other file, just use the same log file:

{  "out_file": "combined.log",  "err_file": "combined.log"}

Note that relatives logs paths will usually be written in the PM2_HOME (~/.pm2/logs).

修改 ~/.pm2 目录下的 conf.js

//conf.js/** * Overidde PM2 configuration */var p    = require('path');module.exports = function(DEFAULT_HOME) {  if (!DEFAULT_HOME)    return false;  var PM2_HOME = DEFAULT_HOME;  var pm2_conf = {    PM2_HOME                 : PM2_HOME,    PM2_LOG_FILE_PATH        : p.join(PM2_HOME, 'pm2.log'),    PM2_PID_FILE_PATH        : p.join(PM2_HOME, 'pm2.pid'),    DEFAULT_PID_PATH         : p.join(PM2_HOME, 'pids'),    //例如修改默认的 pm2 logs的位置.     DEFAULT_LOG_PATH         : '/data/pm2logs',    DUMP_FILE_PATH           : p.join(PM2_HOME, 'dump.pm2'),    DAEMON_RPC_PORT          : p.join(PM2_HOME, 'rpc.sock'),    DAEMON_PUB_PORT          : p.join(PM2_HOME, 'pub.sock'),    INTERACTOR_RPC_PORT      : p.join(PM2_HOME, 'interactor.sock'),    GRACEFUL_TIMEOUT         : parseInt(process.env.PM2_GRACEFUL_TIMEOUT) || 8000,    GRACEFUL_LISTEN_TIMEOUT  : parseInt(process.env.PM2_GRACEFUL_LISTEN_TIMEOUT) || 3000,    CONCURRENT_ACTIONS       : parseInt(process.env.PM2_CONCURRENT_ACTIONS) || 1,    DEBUG                    : process.env.PM2_DEBUG || false,    WEB_INTERFACE            : parseInt(process.env.PM2_API_PORT)  || 9615,    MODIFY_REQUIRE           : process.env.PM2_MODIFY_REQUIRE || false,    PM2_LOG_DATE_FORMAT      : process.env.PM2_LOG_DATE_FORMAT !== undefined ? process.env.PM2_LOG_DATE_FORMAT : 'YYYY-MM-DD HH:mm:ss',    INTERACTOR_LOG_FILE_PATH : p.join(PM2_HOME, 'agent.log'),    INTERACTOR_PID_PATH      : p.join(PM2_HOME, 'agent.pid'),    INTERACTION_CONF         : p.join(PM2_HOME, 'agent.json5')  };  return pm2_conf || null;};

修改完之后还不是立即生效.
执行一下 pm2 kill 来 杀掉 pm2 然后 执行 pm2 start 你的配置 来使修改生效.
