線上部署
1.安裝python3
sudo mkdir /usr/local/python3 # 創(chuàng)建安裝目錄
$ wget --no-check-certificate https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz # 下載 Python 源文件
# 注意：wget獲取https的時(shí)候要加上：--no-check-certifica
$ tar -xzvf Python-3.6.2.tgz # 解壓縮包
$ cd Python-3.6.2 # 進(jìn)入解壓目錄
sudo ./configure --prefix=/usr/local/python3 # 指定創(chuàng)建的目錄
sudo make
sudo make install # 編譯安裝
2.配置兩個(gè)版本共存
創(chuàng)建 python3 的軟鏈接：
$ sudo ln -s /usr/local/python3/bin/python3 /usr/bin/python3
3.安裝pip
# 下載源代碼
$ wget --no-check-certificate https://github.com/pypa/pip/archive/9.0.1.tar.gz
$ tar -zvxf 9.0.1.tar.gz # 解壓文件
$ cd pip-9.0.1
$ python3 setup.py install # 使用 Python 3 安裝
創(chuàng)建鏈接：
$ sudo ln -s /usr/local/python3/bin/pip /usr/bin/pip3
升級(jí) pip
$ pip install --upgrade pip
3.安裝gunicorn
創(chuàng)建虛擬環(huán)境
cd /home/www/blog
mkdir venv
python3 -m venv venv
激活虛擬環(huán)境：
source venv/bin/activate
然后根據(jù)requirements.txt文件安裝依賴包：
pip3 install -r requirements.txt
安裝gunicorn
pip3 install gunicorn
啟動(dòng)服務(wù)：
gunicorn -w 4 -b 127.0.0.1:8000 manager:app
4.nignx配置

4.安裝supervisor進(jìn)程守護(hù)
安裝supervisor在/www/supervisord目錄下
$ pip install supervisor
$ echo_supervisord_conf > supervisord.conf # 生成 supervisor 默認(rèn)配置文件
$ vim supervisor.conf # 修改 supervisor 配置文件役衡，添加 gunicorn 進(jìn)程管理
線上文件如下

在/www/supervisord/conf/下創(chuàng)建文件ttl.conf
[program:ttl]
command=/www/wwwroot/api_ttl_pxx_com/venv/bin/gunicorn -w4 -b 127.0.0.1:8000 manager:app ;supervisor啟動(dòng)命令
directory=/www/wwwroot/api_ttl_pxx_com ; 項(xiàng)目的文件夾路徑
startsecs=0 ; 啟動(dòng)時(shí)間
stopwaitsecs=0 ; 終止等待時(shí)間
autostart=true ; 是否自動(dòng)啟動(dòng)
autorestart=true ; 是否自動(dòng)重啟
stdout_logfile=/www/wwwlogs/ttl.log ; log 日志
stderr_logfile=/www/wwwlogs/ttl.err ; 錯(cuò)誤日志
使用 supervsior 啟動(dòng) gunicorn
$ sudo supervisord -c supervisord.conf
$ sudo supervisorctl start ttl
然后接著查看/etc/rc.local的權(quán)限
[root@openstack ~]# ll /etc/rc.local
lrwxrwxrwx. 1 root root 13 1月 29 10:45 /etc/rc.local -> rc.d/rc.local
[root@openstack ~]# ll /etc/rc.d/rc.local
-rw-r--r--. 1 root root 473 1月 25 23:52 /etc/rc.d/rc.local
/etc/rc.d/rc.local沒有執(zhí)行權(quán)限襟己，于是按說明的內(nèi)容執(zhí)行：
[root@openstack ~]# chmod +x /etc/rc.d/rc.local
[root@openstack ~]# ll /etc/rc.d/rc.local
-rwxr-xr-x. 1 root root 473 1月 25 23:52 /etc/rc.d/rc.local
在開機(jī)文件rc.loacl中添加開機(jī)啟動(dòng)
