supervisor的安装与使用

1. 安装supervisor，yum方式安装

```css
yum install python-setuptools
yum install supervisor
easy_install supervisor
```
2. 配置supervisor，创建目录

```css
mkdir /etc/supervisor
```
3. 初始化一个配置文件

```css
echo_supervisord_conf>/etc/supervisor/supervisord.conf
```

4.
```css
cd /etc/supervisor
vim supervisord.conf
```
5. 在supervisord.conf最下面添加下面的两行，指向指定的文件夹

```css
[include]
files = /etc/supervisor/conf.d/*.ini
```
6. 创建supervisor.sock

```css
sudo touch /var/run/supervisor.sock
sudo chmod 777 /var/run/supervisor.sock
```
7. 在/etc/supervisor目录下创建一个文件夹conf.d

```css
mkdir /etc/supervisor/conf.d
```
8. 在该目录下新建一个api.ini文件。

```css
cd /etc/supervisor/conf.d
vi api.ini
```
```css
[program:api]
command=dotnet /home/api/Sunc_Web_Api3.0/Sunc_Web_Api3.0.dll
directory=/home/api/Sunc_Web_Api3.0/
autostart=true
autorestart=true
startretries=10
startsecs=1
user=root
priority=999
stderr_logfile=/home/log/api.err.log
stdout_logfile=/home/log/api.out.log
environment=ASPNETCORE_ENVIRONMENT=Production
stopsiginal=INT
```
9. 创建文件夹

```css
mkdir /home/api
mkdir /home/log
```
10. 启动supervisor服务，以root身份运行

```css
supervisord -c /etc/supervisor/supervisord.conf
```
11. 配置supervisor开机启动

```css
cd /usr/lib/systemd/system/
vi /usr/lib/systemd/system/supervisord.service
```
```css
[Unit]
Description=Supervisor daemon

[Service]
Type=forking
ExecStart=/usr/bin/supervisord -c /etc/supervisor/supervisord.conf
ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown
ExecReload=/usr/bin/supervisorctl $OPTIONS reload
KillMode=process
Restart=on-failure
RestartSec=40s

[Install]
WantedBy=multi-user.target
```
12. 判断是否设置成功

```css
systemctl enable supervisord.service
```
13. 是否能够开机自启

```css
systemctl daemon-reload
systemctl is-enabled supervisord
```
14. supervisor的网页端显示

```css
cd /etc/supervisor
vim supervisord.conf

15. 总结命令

```css
yum -y remove supervisor
sudo systemctl stop supervisor
sudo systemctl start supervisor
sudo systemctl restart supervisor
sudo systemctl status supervisor
sudo supervisorctl update
```
16. supervisor 重启失败原因可能是端口占用，kill之后，再次启动
