原來使用Apache2和mod_wsgi來部署flask程序粮彤，用起來挺好姜骡。后來程序更新后安裝mod_wsgi一直成問題，所以就放棄了惫周，決定采用uWsgi和nginx組合康栈。
uwsgi的配置
uwsgi的配置文件不算太復(fù)雜喷橙，按以下格式配置即可：
[uwsgi]
socket = 127.0.0.1:8000 #注： 指定某個(gè)固定端口
processes = 4 #注：跑幾個(gè)進(jìn)程，這里用4個(gè)進(jìn)程
threads = 2
master = true
module = worksite
callable = app
memory-report = true
touch-reload = /usr/local/etc/uwsgi.ini
logto = /usr/local/var/log/uwsgi.log
wsgi-disable-file-wrapper = true
其中最后一項(xiàng)是因?yàn)槭褂肍lask下載文件時(shí)采用動(dòng)態(tài)生成的方式贰逾，采用了BytesIO模塊菠秒，下載時(shí)直接報(bào)錯(cuò)。Google了一些文章才知道要加上這么一句稽煤。
這個(gè)文件保存為uwsgi.ini，放在/usr/local/etc/目錄下即可轧简。
nginx的配置
nginx的配置也不復(fù)雜匾二，主要配置如下：
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$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;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:8000;
# root html;
# index index.html index.htm;
}
location /static/ {
root /usr/local/var/worksite/;
}
location /upload/ {
root /usr/local/var/worksite/;
}
location /image/ {
alias /Users/huangtao/OneDrive/圖片/本機(jī)照片/;
autoindex on;
}
}
}
核心的一句在location / 通過“uwsgi_pass 127.0.0.1:8000;”將其轉(zhuǎn)發(fā)給uwsgi來處理。
其他的一些配置均為靜態(tài)文件的配置皮璧。
上述配置文件為/usr/local/etc/nginx/nginx.conf
自動(dòng)啟動(dòng)上述服務(wù)
要想讓上述服務(wù)自動(dòng)啟動(dòng)分飞，需要配置相應(yīng)的plist文件，主要有兩個(gè)譬猫。
- 一個(gè)是uwsgi.plist，文件內(nèi)容為：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>KeepAlive</key>
<true/>
<key>Label</key>
<string>uwsgi</string>
<key>ProgramArguments</key>
<array>
<string>/usr/local/bin/uwsgi</string>
<string>/usr/local/etc/uwsgi.ini</string>
</array>
</dict>
</plist>
- 第二個(gè)是nginx.plist别洪，其內(nèi)容是：
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>ProgramArguments</key>
<array>
<string>/usr/local/bin/nginx</string>
<string>-c</string>
<string>/usr/local/etc/nginx/nginx.conf</string>
</array>
<key>Label</key>
<string>nginx</string>
<key>KeepAlive</key>
<true/>
</dict>
</plist>
上述文件編輯完成后柳刮，將其放入/Library/LaunchDaemons/目錄下即可。重啟系統(tǒng)即可看到上述服務(wù)已經(jīng)啟動(dòng)秉颗。
