部署备忘
1、基本环境
centos7自带python2.7环境和web.py一致，如果要使用其他环境，推荐使用virtualenv进行管理
安装过程能不解压安装就不使用解压安装
换为阿里云的yum源
cd /etc/yum.repos.d
sudo mv CentOS-Base.repo CentOS-Base.repo.bak
sudo wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
sudo wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-7.repo
yum clean all
yum makecache
easy_install
yum install python-setuptools
pip
yum -y install epel-release
yum -y install python-pip
virtualenv 不一定要
pip install virtualenv
Nginx
yum install nginx
gcc
yum install gcc
uwsgi环境
yum install python-devel mysql-devel zlib-devel openssl-devel
uwsgi
pip install uwsgi
yum清理
yum clean all
2、uwsgi Nginx配置文件修改 参考 https://www.tuicool.com/articles/qEVrYn
uwsgi 的配置文件 可支持xml yaml ini等格式。这里使用ini格式的配置文件。默认路径为/etc/uwsgi.ini
[uwsgi]
#使用动态端口，启动后将端口号写入以下文件中
socket = /tmp/uwsgi_vhosts.sock
#也可以指定使用固定的端口
#socket=127.0.0.1:9031
pidfile=/var/run/uwsgi.pid
daemonize=/var/log/uwsgi.log
chdir=你的www目录
wsgi-file=启动wsgi的py
master=true
vhost=true
gid=nginx
uid=nginx
#性能相关的一些参数，具体内容查看官网文档
workers=50
max-requests=5000
limit-as=512
创建uwsgi开机自启动脚本，便于进行系统管理 vi /etc/init.d/uwsgi，内容如下：
#! /bin/sh
# chkconfig: 2345 55 25
# Description: Startup script for uwsgi webserver on Debian. Place in /etc/init.d and
# run 'update-rc.d -f uwsgi defaults', or use the appropriate command on your
# distro. For CentOS/Redhat run: 'chkconfig --add uwsgi'
### BEGIN INIT INFO
# Provides: uwsgi
# Required-Start: $all
# Required-Stop: $all
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: starts the uwsgi web server
# Description: starts uwsgi using start-stop-daemon
### END INIT INFO
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="uwsgi daemon"
NAME=uwsgi
DAEMON=/usr/bin/uwsgi
CONFIGFILE=/etc/$NAME.ini
PIDFILE=/var/run/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
set -e
[ -x "$DAEMON" ] || exit 0
do_start() {
$DAEMON $CONFIGFILE || echo -n "uwsgi already running"
}
do_stop() {
$DAEMON --stop $PIDFILE || echo -n "uwsgi not running"
rm -f $PIDFILE
echo "$DAEMON STOPED."
}
do_reload() {
$DAEMON --reload $PIDFILE || echo -n "uwsgi can't reload"
}
do_status() {
ps aux|grep $DAEMON
}
case "$1" in
status)
echo -en "Status $NAME: \n"
do_status
;;
start)
echo -en "Starting $NAME: \n"
do_start
;;
stop)
echo -en "Stopping $NAME: \n"
do_stop
;;
reload|graceful)
echo -en "Reloading $NAME: \n"
do_reload
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload}" >&2
exit 3
;;
esac
exit 0
修改脚本属性为可执行
chmod 755 /etc/init.d/uwsgi
启用开机自动启动
chkconfig uwsgi on
启动uwsgi服务
service uwsgi start
配置nginx下的uwsgi站点 例如新增以下一个站点mysite。
vi /etc/nginx/conf.d/mysite.conf
server {
listen 9091;
server_name localhost;
root /www/mysite; --你的www目录
index index.html index.htm;
access_log /var/log/nginx/mysite_access.log;
error_log /var/log/nginx/mysite_error.log;
location / {
#使用动态端口
uwsgi_pass unix:///tmp/uwsgi_vhosts.sock;
#uwsgi_pass 127.0.0.1:9031;
include uwsgi_params;
uwsgi_param UWSGI_SCRIPT uwsgi;
uwsgi_param UWSGI_PYHOME $document_root;
uwsgi_param UWSGI_CHDIR $document_root;
}
}
启动Nginx服务
service nginx start
chkconfig nginx on
访问一直是attempt to write a readonly database django，修改数据库文件用户组无效的情况下，需要修改数据库文件的用户组为nginx
chown -R nginx:nginx /home/jack/
查询当前nginx配置文件位置的方法
nginx -t
查看端口占用以及解除
netstat -lpnp
kill -9 pid
服务器重启
nginx
ngnix -s reload
python包位置
/usr/lib/python2.x(3.x)/site-packages/
