安裝
可以用Python的pip工具進行安裝
sudo pip install supervisor也可以使用Linux的包管理命令安裝
sudo apt-get install supervisor配置
執行如下命令可以檢視預設的配置
echo_supervisord_conf如果需要修改預設的配置，可以執行下面命令生成一個預設的配置檔案
echo_supervisord_conf > /etc/supervisord.conf修改預設配置
預設配置檔案中的
supervisord.sock、supervisord.log以及supervisord.pid是放在/tmp目錄下，這個目錄存放的是Linux中的臨時檔案，一旦被系統刪除，就會提示unix:///tmp/supervisor.sock no such file，所以我們要把這三個檔案放到其他目錄中儲存。
此處注意中文註釋的幾個需要修改的地方
[unix_http_server]
;此處修改為/var/run目錄，避免被系統刪除
file=/var/run/supervisor.sock ; the path to the socket file
;chmod=0700 ; socket file mode (default 0700)
;chown=nobody:nogroup ; socket file uid:gid owner

;port=127.0.0.1:9001 ; ip_address:port specifier, *:port for all iface
;username=user ; default is no username (open server)
;password=123 ; default is no password (open server)
[supervisord]
;此處修改為/var/log/supervisor目錄

; added by defining them in separate [rpcinterface:x] sections.
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
; The supervisorctl section configures how supervisorctl will connect to
; supervisord. configure it match the settings in either the unix_http_server
; or inet_http_server section.
[supervisorctl]
;此處是關鍵，否則執行supervisorctl status會爆出unix:// not found錯誤
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL for a unix socket
;serverurl=http://127.0.0.1:9001 ; use an http:// url to specify an inet socket

; The [include] section can just contain the "files" setting. This
; setting can list multiple files (separated by whitespace or
; newlines). It can also contain wildcards. The filenames are
; interpreted as relative to this file. Included files *cannot*
; include files themselves.
；在最後加上include，新增的配置將在/etc/supervisord.d/conf.d目錄下並以.conf結尾
[include]
files = /etc/supervisord.d/conf.d/*.conf上面的一些目錄如果做了修改首先要建立這些目錄，並且賦予相應的許可權
sudo chmod 777 /var/run
sudo chmod 777 /var/log/supervisor現在我們啟動服務
supervisord -c /etc/supervisord.conf此處最好別用root許可權啟動，否則可能導致後面php artisan命令出錯
現在我們檢視程式
pgrep supervisord | xargs ps -u --pidUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 13744 0.0 1.7 226320 17460 ? Ss 1月12 0:08 /bin/python /usr/bin/supervisord -c /etc/supervisord.conf具體專案配置
Supervisorctl 是 Supervisord 的一個命令列客戶端工具，啟動時需要指定與 Supervisord 使用同一份配置檔案
我們在上面預設配置檔案中加入了[include]，所以我們在/etc/supervisord.d/conf.d下新建一個配置檔案larashop-worker.conf
[program:larashop-worker] ;專案名稱
process_name=%(program_name)s_%(process_num)02d
command=php (填入你的artisan路徑)/artisan queue:work redis --sleep=3 --tries=3 ;需要啟動的命令
autostart=true
autorestart=true
user=root ;此處填入你執行WEB應用的使用者
numprocs=8 ;程式數
redirect_stderr=true ;把 stderr 重定向到 stdout，預設 false
stdout_logfile=/var/log/supervisor/larashop-queue.log ;注意分配好日誌資料夾許可權配置完成後我們執行
supervisorctl reread # 讀取有更新（增加）的配置檔案，不會啟動新新增的程式
supervisorctl update # 重啟配置檔案修改過的程式
supervisorctl start larashop-worker:* # 啟動 larashop-worker 程式執行
supervisorctl status # 檢視狀態看到
larashop-worker:larashop-worker_00 RUNNING pid 13769, uptime 14:03:33
larashop-worker:larashop-worker_01 RUNNING pid 13770, uptime 14:03:33
larashop-worker:larashop-worker_02 RUNNING pid 13767, uptime 14:03:33
larashop-worker:larashop-worker_03 RUNNING pid 13768, uptime 14:03:33
larashop-worker:larashop-worker_04 RUNNING pid 13765, uptime 14:03:33
larashop-worker:larashop-worker_05 RUNNING pid 13766, uptime 14:03:33
larashop-worker:larashop-worker_06 RUNNING pid 13763, uptime 14:03:33
larashop-worker:larashop-worker_07 RUNNING pid 13764, uptime 14:03:33說明Laravel佇列已經開始正常執行了
如果在Laravel中修改了佇列程式碼，需要重啟Supervisor才能生效
可能出現的問題
1. ERROR (spawn error)
此時如果提示
larashop-worker:larashop-worker_00: ERROR (spawn error)
...先檢查上述的日誌目錄有沒有許可權，如果許可權正常，則進入上面設定的日誌目錄檢視日誌檔案
我這裡進入var/log/supervisor檢視日誌檔案larashop-queue.conf
可以看到錯誤均為
PHP Parse error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in xxx/artisan on line 33然後我進入Laravel目錄，使用
sudo php artisan 你的命令執行artisan命令，同樣爆出這個錯誤。所以原因在於啟動supervisord和服務端的時候使用了root許可權導致
先將原來的程式kill掉，使用非root許可權重新執行服務端和客戶端即可成功執行
2. unix:///tmp/supervisor.sock no such file
在服務端配置檔案中將/tmp/supervisor.sock修改為var/run/supervisor.sock
3. supervisorctl start錯誤
執行supervisorctl start 你的專案名稱，遲遲不出結果，按ctrl+c後爆出錯誤
Traceback (most recent call last):
File "/bin/supervisorctl", line 11, in <module>
...建議kill掉supervisord的程式，然後重新用pip安裝一次，並重新配置一遍預設配置檔案
