部署前需要关闭防火墙：
`iptables -F`
### 安装python3
环境centos7.2
下载、解压（编译安装，把下载好的python3安装包解压）：
Linux下默认系统自带python2.7的版本，这个版本被系统很多程序所依赖，所以不建议删除，如果使用最新的Python3那么我们知道编译安装源码包和系统默认包之间是没有任何影响的，所以可以安装python3和python2共存
首先去python官网下载python3的源码包，网址：https://www.python.org/
进去之后点击导航栏的Downloads，也可以鼠标放到Downloads上弹出菜单选择Source code，就是源码包的意思，这里选择最新版本36.2，当然下面也有很多其他历史版本，点进去之后页面下方可以看到下载链接，包括源码包、Mac OSX安装包、Windows的安装包
tar -xvf Python-3.6.2.tgz
* * * * *
进入目录：
~~~
cd Python-3.6.2/
~~~
添加配置：
~~~
./configure --with-ssl --prefix=/usr/python
~~~
这里配置自己的安装目录，接下来编译源码、安装：
~~~
make && make install
~~~
如果出现错误提示缺少zlib...啥的则需要安装zlib相关依赖包
~~~
yum -y install zlib*
~~~
注：如果安装后出现```Ignoring ensurepip failure: pip 9.0.1 requires SSL/TLS```
则 ```yum install -y openssl-devel```
2、进入 Python安装包,修改Module路径的setup文件：
~~~
vim Modules/Setup
~~~
找到下面一行代码，去掉注释：
~~~
#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
去掉注释
zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
~~~
系统中原来的python在/usr/bin/python，通过ls -l可以看到，python是一个软链接，链接到本目录下的python2.7
我们可以把这个删除，也可以新建一个python3的软链接，只不过执行时python要改成python3，或者python脚本头部声明要改为#!/usr/bin/python3
```
ln -s /usr/python/bin/python3 /usr/bin/python3
```
#### 安装pip
~~~
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
python3 get-pip.py
~~~
如果pip安装模块时提示
~~~
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
~~~
则需要安装openssl
~~~
yum install -y openssl-devel
~~~
然后重新编译安装即可
#### 安装virtualenv
~~~
pip install virtualenv
mkdir myproject
cd myproject
virtualenv --no-site-packages venv (指定python版本：virtualenv -p /usr/bin/python3 venv)
linux:source venv/bin/activate windows:venv\Scripts\activate
deactivate 退出
~~~
注：如果出现 ```bash: pip: command not found```
首先查找pip安装目录 ```find / -name pip```
然后建立软链 ```ln -s /usr/python/bin/pip /usr/bin/pip ```
#### 安装uwsgi
~~~
pip install uwsgi
~~~
配置uwsgi
在网站根目录下创建config.ini文件，写入以下内容
~~~
[uwsgi]
# uwsgi 启动时所使用的地址与端口
socket = 127.0.0.1:8001
# 指向网站目录
chdir = /home/project/flask/
# python 启动程序文件
wsgi-file = manage.py
# python 程序内用以启动的 application 变量名
callable = app
# 处理器数
processes = 4
# 线程数
threads = 2
#状态检测地址
stats = 127.0.0.1:9191
~~~
#### 安装nginx
~~~
yum -y install nginx
~~~
配置nginx
~~~
vim /etc/nginx/conf.d/default.conf
server{
listen 80;
server_name www.chenyy.xin;
root /home/project/flask;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:8001; # 指向uwsgi 所应用的内部地址,所有请求将转发给uwsgi 处理
uwsgi_param UWSGI_PYHOME /home/project/flask/flask_env361; # 指向虚拟环境目录
uwsgi_param UWSGI_CHDIR /home/project/flask; # 指向网站根目录
uwsgi_param UWSGI_SCRIPT manage:app; # 指定启动程序
}
}
开启
/bin/systemctl start nginx.service
重启
/bin/systemctl restart nginx.service
~~~
#### 安装supervisor
~~~
yum install python-setuptools
pip install supervisor
~~~
测试是否安装成功
~~~
echo_supervisord_conf
~~~
创建配置文件
~~~
mkdir -m 755 -p /etc/supervisor/
cd /etc
echo_supervisord_conf > /etc/supervisor/supervisord.conf
cd supervisor
~~~
创建项目配置文件目录
~~~
mkdir -m 755 conf.d
cd /etc/supervisor/conf.d
vim flask.conf
[program:flask]
command =/home/project/flask/flask_env361/bin/uwsgi /home/project/flask/config.ini
directory =/home/project/flask
user =root
autostart=true
autorestart=true
startsecs=5
priority=1
stopasgroup=true
killasgroup=true
stderr_logfile=/home/project/log/error.log#要确保该目录存在
~~~
在主配文档中引入flask.conf
~~~
vim supervisord.conf
~~~
找到include
~~~
;[include]
;files = relative/directory/*.ini
//改为
[include]
files = ./conf.d/*.conf
~~~
启动supervisor
~~~
supervisord -c supervisord.conf
~~~
如果出现以下错误
~~~
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.
For help, use /root/.pyenv/versions/2.7.6/bin/supervisord -h
~~~
找到 supervisor.sock
~~~
unlink supervisor.sock
~~~
重新启动supervisor
用supervisorctl查看已经被监控的program
~~~
(flask_env361) [root@iZ2zefw4wlcm0he1pjkawoZ supervisor]# supervisorctl
flask RUNNING pid 1764, uptime 0:59:45
~~~
如果supervisorctl没效果，换成
~~~
supervisorctl -c /etc/supervisor/supervisord.conf
~~~
重启监控服务
~~~
supervisorctl reload
~~~
异常解决
~~~
[root@iZ2zefw4wlcm0he1pjkawoZ supervisor]# supervisorctl
unix:///tmp/supervisor.sock no such file
supervisor> reload
