CentOS部署Python3的一些注意事项

# json_data=json.dumps(hqs,cls=__default)
# 安装Nginx
yum -y install gcc gcc-c++ autoconf automake make  zlib zlib-devel openssl openssl--devel pcre pcre-devel
cd /opt
wget http://nginx.org/download/nginx-1.9.14.tar.gz
mkdir nginx
tar zxvf nginx-1.9.14.tar.gz
cd nginx-1.9.14
./configure --prefix=/opt/nginx --with-http_stub_status_module --with-http_gzip_static_module
make && make install

# 启动nginx
/opt/nginx/sbin/nginx

# 拷贝文件至远程主机
scp -r //Users/Irving/Desktop/python/stockhq/ [email protected]:/opt/
scp -r //Users/Irving/Desktop/python/stockhq/data/ [email protected]:/opt/stockhq/data/

# 升级python3
yum install gcc zlib-devel make
# 下载python
wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz
解压缩、编译和安装
tar -zxvf Python-3.5.1.tgz
cd Python-3.5.1
./configure –prefix=/opt/python3
make all
make install
清除之前编译的可执行文件及配置文件。
make clean
清除所有生成的文件
make distclean
查看安装的新版本信息
/opt/python3/bin/python3 -V
做个软连接到当前用户的bin目录(注意:如果已安装了puython2.6 先删除执行 rm -rf /usr/bin/python)
ln -s /opt/python3/bin/python3 /usr/bin/python

升级了默认的python导致报错 File “/usr/bin/yum”, line 30
vim /usr/bin/yum    #将!/usr/bin/python改成!/usr/bin/python2.6即可。
# 安装pip3
ln -s "/opt/python3/bin/pip3" /usr/local/bin/pip3
# 安装包
pip3 install requests pymysql sqlalchemy flask flask_json simplejson
#安装
yum install supervisor
# 查看配置信息
