supervisor是一個很好的守護程序管理工具，配置方面自動啟動，日志輸出，自動切割日志等等一系列強大功能，下面是在CentOS下安裝使用supervisor的記錄。

安裝

# epel源yum install epel-release# 安裝supervisoryum install -y supervisor# 開機自啟動systemctl enable supervisord# 啟動supervisord服務systemctl start supervisord Bash

配置路徑

# 主配置文件/etc/supervisord.conf# 運行程序配置文件夾/etc/supervisord.d/Bash

操作命令

systemctl stop supervisordsystemctl start supervisordsystemctl status supervisord# 重新加載配置文件，不影響正在運行的程序systemctl reload supervisordsystemctl restart supervisordBash

使用測試

寫一個測試腳本test.php，記錄啟動次數和運行。

<?phptry {  $a = file_get_contents('./times.json');} catch (Exception $e) {  $a = 0;}$a ++;file_put_contents('./times.json', $a);echo date('Y-m-d H:i:s') . " 這是第{$a}次啟動!!!!" . PHP_EOL;$i = 1;while (1) {  echo date('Y-m-d H:i:s') . " 第{$i}次輸出" . PHP_EOL;  $i ++;  sleep(5);}

PHP

在程序配置文件夾/etc/supervisord.d中添加test.ini：

[program:test]directory=/home/wwwroot/test.cccommand=php test.phpautostart=trueautorestart=truestderr_logfile=/home/wwwroot/test.cc/log/error.logstdout_logfile=/home/wwwroot/test.cc/log/out.logIni

上面只是一些必要的基本配置，更詳細的配置參考：

;[program:theprogramname];command=/bin/cat       ; the program (relative uses PATH, can take args);process_name=%(program_name)s ; process_name expr (default %(program_name)s);numprocs=1          ; number of processes copies to start (def 1);directory=/tmp        ; directory to cwd to before exec (def no cwd);umask=022           ; umask for process (default None);priority=999         ; the relative start priority (default 999);autostart=true        ; start at supervisord start (default: true);autorestart=true       ; retstart at unexpected quit (default: true);startsecs=10         ; number of secs prog must stay running (def. 1);startretries=3        ; max # of serial start failures (default 3);exitcodes=0,2         ; 'expected' exit codes for process (default 0,2);stopsignal=QUIT        ; signal used to kill process (default TERM);stopwaitsecs=10        ; max num secs to wait b4 SIGKILL (default 10);user=chrism          ; setuid to this UNIX account to run the program;redirect_stderr=true     ; redirect proc stderr to stdout (default false);stdout_logfile=/a/path    ; stdout log path, NONE for none; default AUTO;stdout_logfile_maxbytes=1MB  ; max # logfile bytes b4 rotation (default 50MB);stdout_logfile_backups=10   ; # of stdout logfile backups (default 10);stdout_capture_maxbytes=1MB  ; number of bytes in 'capturemode' (default 0);stdout_events_enabled=false  ; emit events on stdout writes (default false);stderr_logfile=/a/path    ; stderr log path, NONE for none; default AUTO;stderr_logfile_maxbytes=1MB  ; max # logfile bytes b4 rotation (default 50MB);stderr_logfile_backups=10   ; # of stderr logfile backups (default 10);stderr_capture_maxbytes=1MB  ; number of bytes in 'capturemode' (default 0);stderr_events_enabled=false  ; emit events on stderr writes (default false);environment=A=1,B=2      ; process environment additions (def no adds);serverurl=AUTO        ; override serverurl computation (childutils)Ini
