preface
Some time ago, E5SubBot was used to renew 365 E5. After use, it was found that the E5SubBot project was indeed effective. Because the program was previously run in the background using nohup, the program will stop after running for a period of time. In order to solve this problem, I wrote a shell script myself, and then solved this problem with the help of the planned task. Later, I found that I had made a detour again. Wouldn't it be better to use systemd services?
However, I still need to record what I have written. It's meaningless to delete it directly. Here is my first script.
#!/ bin/bash pid=`ps -aux | grep E5SubBot | grep -v 'grep' | awk '{print $2}'` if [ "$pid" != "" ]; then echo "running ..." else echo "$(date '+%Y/%m/%d %H:%M:%S'):no run,starting..." >> /root/e5cron.log echo "no run" cd /root/e5sub/ && nohup /root/e5sub/E5SubBot >> /root/e5sub/e5sub-$(date +%Y%m%d%H%M%S).log & fi
Then, in coordination with the scheduled task, execute the shell written by yourself every two hours to determine whether it has stopped running. If it has stopped, start it. If it has not stopped, ignore it.
* */2 * * * /root/e5bot.sh
However, the above method is not a perfect solution. Later, I changed the scheme of scheduling tasks to the system d service mode. The operating system of the server I used is Centos 7. The specific process is as follows.
setup script
The following is my specific installation process in Centos 7 operating system.
Access E5SubBot project address
E5SubBot Project Github Address: https://github.com/iyear/E5SubBot/releases
Select the appropriate version
Select the corresponding version to download according to the specific situation of your server. Here I choose the E5SubBot_Linux_64bit version, which is currently used by most servers.
wget https://github.com/iyear/E5SubBot/releases/download/v0.2.1/E5SubBot_Linux_64bit.tar.gz
Unzip files
Unzip the file you just downloaded.
tar xvf E5SubBot_Linux_64bit.tar.gz
The following four files are obtained, and we need to use the binary file E5SubBot.
LICENSE README.md README_zhCN.md E5SubBot
Create folders and move files
Move the extracted file E5SubBot to the corresponding directory.
#Create Folder mkdir /opt/e5sub #Move files mv E5SubBot /opt/e5sub/E5SubBot #Add execution permission to the file chmod a+x /opt/e5sub/E5SubBot
Configure E5Subbot
Create a config.yml file in the/opt/e5sub directory to configure the details of the telegram bot and mysql. If you don't know how to configure, please read the Configuration 。
vim /opt/e5sub/config.yml
The configuration file contents are as follows:
Bot_token: TOKEN of your TG robot Notice: "Here you can fill in the notification information of the robot" Admin: fill in your tg ID as administrator #socks5: 127.0.0.1:1080 errlimit: 15 cron: "1 */1 * * *" bindmax: 5 mysql: host: localhost port: 3306 user: e5sub password: e5sub database: e5sub
Of course, if you use a domestic server, you need to specify the socks5 attribute to use the proxy server. The following is a description of specific attributes.
| attribute | explain |
|---|
| bot_token | The token of tg robot can be obtained through @ BotFather |
| socks5 | [Optional] It is used to specify the socks5 proxy, for example, 127.0.0.1:1080 |
| notice | Announcement, displayed when using/help |
| admin | Administrator tgid can be accessed through @userinfobot Get, used to manually execute/task tasks and get feedback on task execution in progress |
| errlimit | The maximum number of errors in a single account. When the number of errors in a single account reaches the specified number, the system will automatically unbind and send a notification. If it is set to - 1, there is no limit |
| bindmax | Maximum number of accounts bound to a single account |
| cron | The frequency of calling the api, using cron expressions |
| mysql | Connection information of MySQL database |
Write Systemd unit file
Edit the cell file using the vim editor.
vim /etc/systemd/system/e5sub.service
Copy the following contents into it.
[Unit] Description=Telegram E5Sub Bot [Service] Type=simple WorkingDirectory=/opt/e5sub ExecStart=/opt/e5sub/E5SubBot Restart=always RestartSec=30 [Install] WantedBy=multi-user.target
Set automatic startup
After editing the systemd unit file, you need to reload the service configuration file.
systemctl daemon-reload
Then start the service.
systemctl start e5sub
View service status.
systemctl status e5sub
Finally, set the service auto start.
systemctl enable e5sub
