# 使用nginx和uwsgi部署flask应用
## 安装python3
1. 安装编译python的信赖包
```
yum install -y gcc make libffi-devel zlib-devel bzip2-devel openssl-devel xz-libs wget
```
2. 编译安装python的最新版本
* 从官网下载最新的源代码并解压缩
```
wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz
tar -xvf Python-3.7.3.tar.xz
```
* 编译安装
```
cd Python-3.7.3
#安装到/usr/local下与自带的python区分开
./configure --prefix=/usr/local
make && make install
```
* 设置PATH，更改默认python
```
export PATH="/usr/local/bin:$PATH"
```
## 安装使用uwsgi
为了统一管理，在python的虚拟环境下安装使用uwsgi,不使用全局的uwsgi
```bash
mkdir -p /var/www/flask_api
cd /var/www/flask_api
python -m venv venv
source venv/bin/activate
pip install flask uwsgi
```
接下来可以用uWSGI来跑Flask应用
```
uwsgi --http 0.0.0.0:8080 --home env --wsgi-file flask_uwsgi.py --callable app --master
```
测试上面的程序是否成功
```
curl http://127.0.0.1:8080
```
## 编译安装nginx
1. 安装信赖包
```
yum install pcre-devel gcc make zlib-devel lua-devel perl
```
2. 下载最新版本的openssl和nginx源代码
```
wget https://www.openssl.org/source/openssl-1.1.1b.tar.gz
wget https://nginx.org/download/nginx-1.14.2.tar.gz
```
3. 编译安装
```
tar -xvf openssl-1.1.1b.tar.gz
tar -xvf nginx-1.14.2.tar.gz
cd nginx-1.14.2
./configure --prefix=/usr/local/nginx --with-stream --with-stream_ssl_preread_module --with-http_v2_module --with-http_ssl_module --with-pcre --with-openssl=../openssl-1.1.1b --with-openssl-opt='enable-tls1_3'
make -j 4
make install
```
4. 添加systemctl配置, 添加` /usr/lib/systemd/system/nginx.service`,并将下面内容写入
```
[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
```
5. 修改nginx配置, 先使用`useradd nginx`添加nginx用户, 再将下面内容覆盖/usr/local/nginx/conf/nginx.conf, 最后在/usr/local/nginx/conf下面添加vhosts文件夹，最后所有域名的配置都可以放到这个目录下面。
```nginx
user nginx;
worker_processes 8;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $request_time [$time_local] "$request" '
'$status $body_bytes_sent $bytes_sent $content_length $request_length "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
include vhosts/*.conf;
}
```
