dnmp 中supervisor使用教程

supervisor是用python 实现的,所以安装supervisor容器就要消耗更多空间.

supervisor 单独一个容器用法:

git clone https://github.com/yeszao/dnmp.git

cp docker-compose.sample.yml docker-compose.yml

cp env.sample .env

然后把docker-compose.yml中最下面的supervisor部分的注释解开

  supervisor:(注意顶到头前要空两格)
    build:
     context: ./services/supervisor   //DockerFile目录
     args:
        ALPINE_VERSION: alpine:${ALPINE_VERSION}   //容器镜像
        TZ: "$TZ"
        CONTAINER_PACKAGE_URL: ${CONTAINER_PACKAGE_URL}  //映射ENV文件中的镜像地址
    container_name: supervisor
    ports:
     - "${SUPERVISOR_HOST_PORT_C}:9001"   //映射Web Supervisor管理的端口
    volumes:  //映射目录
     - ${SOURCE_DIR}:/www/:rw
     - ${SUPERVISOR_LOG}:/var/log/supervisor/:rw
     - ${SUPERVISOR_CONFIG}:/etc/supervisor/conf.d/:rw
     - ${SUPERVISOR_CONF_FILE}:/etc/supervisor/supervisord.conf:ro
    command: //启动时执行命令
     - /bin/sh
     - -c
     - |
        supervisord -n -c /etc/supervisor/supervisord.conf
    restart: always
    cap_add:
     - SYS_PTRACE
    networks:
     - default

docker-compose up -d

然后就启动成功了,再访问 9001 端口就会出现supervisor的web管理界面了默认账号user 密码 123 (可在主配置中修改)

在PHP容器中使用supervisor

注意是Php-Cli 如果是 Php-Fpm 则容器启动的时候不能将两个进程全部启动,可在supervisor中添加php-fpm的守护进程

修改过后,增加端口,文件,启动命令

  php:
    build:
      context: ./services/php
      args:
        PHP_VERSION: php:${PHP_VERSION}-alpine
        CONTAINER_PACKAGE_URL: ${CONTAINER_PACKAGE_URL}
        PHP_EXTENSIONS: ${PHP_EXTENSIONS}
        TZ: "$TZ"
    container_name: php
    expose:
      - 9501
    ports:
      - "${SUPERVISOR_HOST_PORT_C}:9001"
    extra_hosts:
      - "www.site1.com:172.17.0.1"
    volumes:
      - ${SOURCE_DIR}:/www/:rw
      - ${PHP_PHP_CONF_FILE}:/usr/local/etc/php/php.ini:ro
      - ${PHP_FPM_CONF_FILE}:/usr/local/etc/php-fpm.d/www.conf:rw
      - ${PHP_LOG_DIR}:/var/log/php
      - ${DATA_DIR}/composer:/tmp/composer
      - ${SUPERVISOR_LOG}:/var/log/supervisor/:rw
      - ${SUPERVISOR_CONFIG}:/etc/supervisor/conf.d/:rw
      - ${SUPERVISOR_CONF_FILE}:/etc/supervisor/supervisord.conf:ro
    restart: always
    command:
     - /bin/sh
     - -c
     - |
        supervisord -n -c /etc/supervisor/supervisord.conf
    cap_add:
      - SYS_PTRACE
    networks:
      - default

php DockerFile 的修改

dnmp/services/php/Dockerfile

ARG PHP_VERSION
FROM ${PHP_VERSION}

ARG TZ
ARG PHP_EXTENSIONS
ARG CONTAINER_PACKAGE_URL


RUN if [ $CONTAINER_PACKAGE_URL ] ; then sed -i "s/dl-cdn.alpinelinux.org/${CONTAINER_PACKAGE_URL}/g" /etc/apk/repositories ; fi


RUN apk update 
	&& apk upgrade 
	&& apk add supervisor 
	&& apk --no-cache add tzdata 
    && cp "/usr/share/zoneinfo/$TZ" /etc/localtime 
    && echo "$TZ" > /etc/timezone 
	&& rm -rf /var/cache/apk/*



COPY ./extensions /tmp/extensions
WORKDIR /tmp/extensions
RUN chmod +x install.sh 
    && sh install.sh 
    && rm -rf /tmp/extensions

ADD ./extensions/install-php-extensions  /usr/local/bin/

增加了这一段安装的命令

RUN apk update 
	&& apk upgrade 
	&& apk add supervisor 
	&& apk --no-cache add tzdata 
    && cp "/usr/share/zoneinfo/$TZ" /etc/localtime 
    && echo "$TZ" > /etc/timezone 
	&& rm -rf /var/cache/apk/*

然后在supervisor子配置文件中测试

[program:php]
command=/usr/local/bin/php -S 0.0.0.0:80
directory=/www/localhost/
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. 10)
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 before SIGKILL (default 10)
user=root                 ; setuid to this UNIX account to run the program
log_stdout=true
log_stderr=true             ; if true, log program stderr (def false)
logfile=/var/log/supervisor/php.log
logfile_maxbytes=1MB        ; max # logfile bytes b4 rotation (default 50MB)
logfile_backups=10          ; # of logfile backups (default 10)
stdout_logfile_maxbytes=20MB  ; stdout 日志文件大小，默认 50MB
stdout_logfile_backups=20     ; stdout 日志文件备份数
stdout_logfile=/var/log/supervisor/php.stdout.log

supervisor web端的进程列表就显示了

OK

当然可以直接用我改好的
