问题

1.为什么使用python3.5？

　　ubuntu使用python3.6在安装uwsgi的时候，老是报错，然后还么有找到原因...

2.定时任务运行报错：
　　1>.TypeError: can only concatenate tuple (not "NoneType") to tuple；
　　　　版本问题需要 django-celery 3.1.17 celery 3.1.25 celery-with-redis 3.0； https://github.com/stanleylst/ansibleUI/issues/2

　　2>.TypeError: __init__() missing 1 required positional argument: 'on_delete'；

　　　　django2.0 on_delete 是必须的； https://blog.csdn.net/qq_38038143/article/details/80286187
　　3>.AttributeError: type object 'BaseCommand' has no attribute 'option_list'；
　　　　升级django-celery 到3.2.2 解决； https://chowyi.com/Django-1-10-celery-worker-%E5%90%AF%E5%8A%A8%E6%8A%A5%E9%94%99/

3.django2.2/mysql ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3；
　　django版本问题，降级到diango 2.2 往下就可以了；

4. You need tcl 8.5 or newer in order to run the Redis test.
　　安装redis时报的错，升级tcl即可； https://www.cnblogs.com/Security-Darren/p/4381932.html

5.nginx负载均衡设置时，命名不能用下划线；
　　upstream myApp {
　　　　server 127.0.0.1:9000;
　　　　}

6.BeautifulReport模块；
　　result.report(filename=now + 'report.html', description=readConfig.title, log_path=report_path)；
　　log_path 参数需要替换成 report_dir 参数

7.redis.exceptions.ResponseError: MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error；
　　redis-cli 输入 config set stop-writes-on-bgsave-error no https://www.jianshu.com/p/3aaf21dd34d6

8.locust 守护进程；　要带小括号　　(locust -f base/performance.py --master &)　　 https://www.cnblogs.com/maoxianfei/p/7987217.html

　　启动slave 运行性能测试　　locust -f base/performance.py --slave --master-host=129.28.187.64

9.定时任务守护进程 django-celery supervisor http://yshblog.com/blog/165

　　supervisord.conf

[program:celery.worker]
;指定运行目录
directory=/home/ubuntu/EasyTest/
;运行目录下执行命令
command=python manage.py celery worker --loglevel=info --logfile /home/ubuntu/EasyTest/celery_logs/celery_worker.log

;启动设置
numprocs=1          ;进程数
autostart=true      ;当supervisor启动时,程序将会自动启动
autorestart=true    ;自动重启

;停止信号,默认TERM
;中断:INT (类似于Ctrl+C)(kill -INT pid)，退出后会将写文件或日志(推荐)
;终止:TERM (kill -TERM pid)
;挂起:HUP (kill -HUP pid),注意与Ctrl+Z/kill -stop pid不同
;从容停止:QUIT (kill -QUIT pid)
stopsignal=INT

;输出日志
stdout_logfile=/home/ubuntu/EasyTest/celery_logs/celery_worker.log
stdout_logfile_maxbytes=10MB  ;默认最大50M
stdout_logfile_backups=10     ;日志文件备份数，默认为10

;错误日志
redirect_stderr=false         ;为true表示禁止监听错误
stderr_logfile=/home/ubuntu/EasyTest/celery_logs/celery_worker_err.log
stderr_logfile_maxbytes=10MB
stderr_logfile_backups=10

[program:celery.beat]
;指定运行目录
directory=/home/ubuntu/EasyTest/
;运行目录下执行命令
command=celery -A EasyTest beat -l info --loglevel info --logfile /home/ubuntu/EasyTest/celery_logs/celery_beat.log

;启动设置
numprocs=1          ;进程数
autostart=true      ;当supervisor启动时,程序将会自动启动
autorestart=true    ;自动重启

;停止信号
stopsignal=INT

　　启动和关闭supervisor

　　　　启动supervisor输入如下命令，使用具体的配置文件执行：

supervisord -c supervisord.conf

　　　　关闭supervisord需要通过supervisor的控制器：

supervisorctl -c supervisord.conf shutdown

　　　　重启supervisord也是通过supervisor的控制器：

supervisorctl -c supervisord.conf reload

10.django 匿名用户限制；

　　装饰器 @login_required

11.异常页面配置 400 403 404 500 https://zhuanlan.zhihu.com/p/38006919

12.gunicorn配置；

　　启动命令：gunicorn -c gunicorn-config.py EasyTest.wsgi:application

　　gunicorn-config.py

# !/usr/bin/env python
# coding=utf-8
from multiprocessing import cpu_count

bind = '127.0.0.1:9000'
daemon = True   # 守护进程

workers = cpu_count() * 2
worker_class = 'gevent'
forwarded_allow_ips = '*'

# 维持TCP链接
keepalive = 6
timeout = 65
graceful_timeout = 10
worker_connections = 65535

# log
capture_output = True
loglevel = 'info'
accesslog = "/tmp/EasyTest_access.log"    #访问日志文件的路径
errorlog = "/tmp/EasyTest_error.log"

　13.nginx配置；

　　nginx启动命令：sudo /usr/local/nginx/sbin/nginx

　　nginx.conf

#user  nobody;
worker_processes  4;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;

            proxy_redirect off;
            proxy_pass http://myApp;
        }
    }
}

14.supervisord启动报错； Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.

　　ps -ef | grep supervisord　　杀掉进程，重新启动；

15.ubuntu--matplotlib显示中文； https://blog.csdn.net/jeff_liu_sky_/article/details/54023745

　　下载simhei.ttf中文字体，放入 .virtualenvs/env/lib/python3.5/site-packages/matplotlib/mpl-data/fonts/ttf 中；

　　代码中设置

import matplotlib as mpl
from matplotlib import pyplot as plt

mpl.rcParams[u'font.sans-serif'] = ['simhei']
mpl.rcParams['axes.unicode_minus'] = False
plt.title(u'测试用例运行结果')

　16.mysql数据库保存时报错：django.db.utils.InternalError: (1153, "Got a packet bigger than 'max_allowed_packet' bytes")

　　插入数据库数据过大导致； https://stackoverflow.com/questions/93128/mysql-error-1153-got-a-packet-bigger-than-max-allowed-packet-bytes

　　在mysql中执行：set global net_buffer_length=1000000; set global max_allowed_packet=1000000000;　　

17.安装jenkins；

sudo apt-get install openjdk-8-jdk

wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -
sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'
sudo apt-get update
sudo apt-get install jenkins

　　执行 sudo apt-get install jenkins 时，可能会遇到各种小问题，可能是python2和python3不兼容，按照提示，修改py源码内容即可；

　　jenkins 密码：/var/lib/jenkins/secrets/initialAdminPassword

　　service jenkins start 开始
　　service jenkins restart 重启
　　service jenkins stop 停止
　　service jenkins status 查看状态
18.jenkins 重启 django + gunicorn 项目：
　　shell重启项目脚本

# !/bin/sh

sudo cp -Rf /var/lib/jenkins/workspace/django-EasyTest/* /home/ubuntu/project/

source /home/ubuntu/.virtualenvs/env/bin/activate

PROCESS=`ps -e | grep gunicorn | awk '{printf "%d\n", $1}'`
echo $PROCESS
for i in $PROCESS
do
    echo "Kill the gunicorn process [ $i ]"
    sudo kill -9 $i
done

cd /home/ubuntu/

echo 'stop server finish!'

sleep 2s

cd /home/ubuntu/project/

gunicorn -c /home/ubuntu/project/gunicorn-config.py EasyTest.wsgi:application

echo 'start server success！！！'

exit 0

　　issues：　　shell 中启动python虚拟环境：　　　　source /home/ubuntu/.virtualenvs/env/bin/activate 　　source: not found

　　　　原因： ls -l `which sh` 提示/bin/sh -> dash

　　　　这说明是用dash来进行解析的。

　　　　改回方法：

　　　　命令行执行：sudo dpkg-reconfigure dash

　　　　在界面中选择no　　

　　　　再ls -l `which sh` 提示/bin/sh -> bash

19.防火墙

　　https://www.cnblogs.com/sweet521/p/5733466.html

　　sudo apt-get install ufw

　　sudo ufw enable

　　sudo ufw default deny　　　　sudo ufw enable|disable
