最强最实用一步步搭建centos配置python3,tornado服务器环境
easyinstall
yum install python-setuptools
rpm方式安装
centos7
yum -y install https://centos7.iuscommunity.org/ius-release.rpm
yum makecache
yum install python36u
yum -y install python36u-pip
yum -y install python36u-devel
centos6.8
wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz
tar -zxvf Python-3.6.4.tgz
cd Python-3.6.4
./configure --prefix=/usr/local/python
make && make install
echo PATH='/usr/local/python/bin/:$PATH' >> /etc/profile
source /etc/profile
virtualenv
easy_install virtualenv
virtualenv .pyenv --python=python3.6
source .pyenv/bin/activate
git
yum install git
进入项目目录,git clone
保存存储username,passwd:
git config credential.helper store
之后执行git pull 输入账号密码后会自动保存下来
安装pip依赖包
pip install -r requirements.txt
安装pycurl报错:
__main__.ConfigurationError: Could not run curl-config: [Errno 2] No such file or directory: 'curl-config': 'curl-config'
缺少依赖包,解决:
yum install gcc libffi-devel python-devel libcurl-devel
报错:
ImportError: pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (openssl)
解决:
pip uninstall pycurl
export PYCURL_SSL_LIBRARY=nss
export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include
pip install pycurl --compile --no-cache-dir
supervisor
supervisor不支持python3,所以我们需要在python2的环境下安装supervisor,再在其中运行python3的服务
deactive # 退出python3虚拟环境
pip install supervisor
mkdir /etc/supervisor
echo_supervisord_conf > /etc/supervisord.conf # 生成默认配置文件
directory = /opt/server/server ; 程序的启动目录
command = /opt/server/.pyenv/bin/python proxy_server.py ; 启动命令
autostart = true ; 在 supervisord 启动的时候也自动启动
startsecs = 5 ; 启动 5 秒后没有异常退出，就当作已经正常启动了
autorestart = true ; 程序异常退出后自动重启
startretries = 3 ; 启动失败自动重试次数，默认是 3
user = root ; 用哪个用户启动
redirect_stderr = true ; 日志重定向
stdout_logfile=/var/log/server/out.log
stderr_log=/var/log/server/err.log
nginx
user nginx;
worker_processes 5; 进程数
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
worker_rlimit_nofile 10240; worker进程的最大打开文件数限制
events {
worker_connections 10000; 一个worker进程同时打开的最大连接数
use epoll; 如果你使用Linux 2.6+，你应该使用epoll。如果你使用*BSD，你应该使用kqueue
}
proxy_next_upstream error;
upstream tornadoes {
server 127.0.0.1:8000;
}
server {
listen 80;
server_name www.example.org *.example.org;
location / {
proxy_pass http://tornadoes;
}
}
mysql
CentOS 7 版本将MySQL数据库软件从默认的程序列表中移除，用mariadb代替了。
yum install mariadb-server mariadb
yum install mysql
systemctl start mariadb #启动MariaDB
