安装python

1，开机初始化的配置iptables -F 清空防火墙/etc/init.d/iptables stop  #关闭iptablessetenforce 0  #暂停selinux#编译安装python3环境准备yum install gcc patch libffi-devel python-devel  zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y#下载python3的源码包wget https://www.python.org/ftp/python/3.4.7/Python-3.4.7.tar.xz#解压缩源码包xz -d Python-3.4.7.tar.xztar -xf Python-3.4.7.tar#切换python3目录cd Python-3.4.7#释放脚本文件./configure --prefix=/opt/python347#编译，编译安装 make && make install  #建立软连接 ln -s /opt/python347/bin/python3 /usr/local/bin/python3 下载 readline  yum install -y readline -devel  查看环境变量:

[root@tencentcloud ~]# echo $PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

 

 

 虚拟环境的安装

#python虚拟环境virtualenv --no-site-packages venv #创建venv虚拟环境#激活虚拟环境source venv/bin/activate#虚拟环境主要是对环境变量进行更改echo $PATH#退出虚拟环境deactivate

 

 

1. 下载NGINX 

wget http://nginx.org/download/nginx-1.14.0.tar.gz

2.解压

tar xf nginx-1.14.0.tar.gz

3. 编译安装三部曲 

 

进入 nginx 目录下 ，注意目录里有个configure 文件./configure --prefix=/opt/nginx-1.14.0make && make install

 

4.开启服务

4.启动nginx，进入sbin目录,找到nginx启动命令cd sbin./nginx #启动./nginx -s stop #关闭./nginx -s reload #重新加载

5.查看conf文件

cat conf/nginx.conf

[root@tencentcloud nginx-1.12.2]# cat conf/nginx.conf#user  nobody;worker_processes  1;#error_log  logs/error.log;#error_log  logs/error.log  notice;#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {    worker_connections  1024;}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 / {            root   html;            index  index.html index.htm;        }        #error_page  404              /404.html;        # redirect server error pages to the static page /50x.html        #        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }        # proxy the PHP scripts to Apache listening on 127.0.0.1:80        #        #location ~ \.php$ {        #    proxy_pass   http://127.0.0.1;        #}        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000        #        #location ~ \.php$ {        #    root           html;        #    fastcgi_pass   127.0.0.1:9000;        #    fastcgi_index  index.php;        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;        #    include        fastcgi_params;        #}        # deny access to .htaccess files, if Apache's document root        # concurs with nginx's one        #        #location ~ /\.ht {        #    deny  all;        #}    }    # another virtual host using mix of IP-, name-, and port-based configuration    #    #server {    #    listen       8000;    #    listen       somename:8080;    #    server_name  somename  alias  another.alias;    #    location / {    #        root   html;    #        index  index.html index.htm;    #    }    #}    # HTTPS server    #    #server {    #    listen       443 ssl;    #    server_name  localhost;    #    ssl_certificate      cert.pem;    #    ssl_certificate_key  cert.key;    #    ssl_session_cache    shared:SSL:1m;    #    ssl_session_timeout  5m;    #    ssl_ciphers  HIGH:!aNULL:!MD5;    #    ssl_prefer_server_ciphers  on;    #    location / {    #        root   html;    #        index  index.html index.htm;    #    }    #}}

 

6.创建软连接

[root@tencentcloud nginx-1.12.2]# ln -s  /sbin/nginx  /sbin/

 

 

 

5.关闭防护墙

chkconfig iptables off  永久关闭。chkconfig|grep ipt

vim /etc/selinux/config

 

 6. 去掉文件里的# 和空行 

egrep -v "^$|#" nginx.conf.defaultegrep -v "^$|#" nginx.conf.default >nginx.conf

　　

 

4. 测试 

curl 10.10.0.1
