## 1.supervisorctl [http://localhost:9001][http_localhost_9001] refused connection ##

#### 1.打开如下的配置： ####

[inet_http_server]         ; inet (TCP) server disabled by default
    port=0.0.0.0:9001        ; (ip_address:port specifier, *:port for all iface)
    username=user              ; (default is no username (open server))
    password=123               ; (default is no password (open server))

## 2.tomcat 启动报错：FATAL Exited too quickly ##

#### 1.这是因为启动 tomcat的方式不对，在linux命令行模式下我们启动可以使用如下脚本 ####

./apache-tomcat-7.0.70/bin/startup.sh

#### 2.在supervisor的启动命令中不能使用这种方式了要使用如下方式： ####

command=/root/tools/apache-tomcat-7.0.70/bin/catalina.sh run

## 3.完整配置文件： ##

#### 1.supervisor 配置文件 ####

#### 2.tomcat 启动文件 tomcat.ini ####

[program:tomcat]
    command=/root/tools/apache-tomcat-7.0.70/bin/catalina.sh run
    stdout_logfile=/root/tools/apache-tomcat-7.0.70/logs/catalina.out
    autostart=true
    autorestart=true
    startsecs=5
    priority=1
    stopasgroup=true
    killasgroup=true

## 4.加载配置文件 ##

supervisord -c /etc/supervisord.conf
