Nginx请求转发到后端服务器/K8S/PaaS
Nginx安装
https://nginx.org/en/download.html
下载nginx
解压:tar –xzf nginx-1.10.3.tar.gz && cd nginx-1.10.3 配置:./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module 编译安装 sudo make && sudo make install 启动:/usr/local/nginx/sbin/nginx 查看进程:ps –aux | grep nginx 验证 curl http://127.0.0.1/复制代码
如果安装时提示缺少
compiler cc
,需要安装gcc,可以从网址http://mirrors.aliyun.com/centos/7/os/x86_64/Packages/
下载以下包:
mpfr-3.1.1-4.el7.x86_64.rpm libmpc-1.0.1-3.el7.x86_64.rpm kernel-headers-3.10.0-123.el7.x86_64.rpm glibc-headers-2.17-55.el7.x86_64.rpm glibc-devel-2.17-55.el7.x86_64.rpm cpp-4.8.2-16.el7.x86_64.rpm gcc-4.8.2-16.el7.x86_64.rpm复制代码
然后安装:
rpm -Uvh *.rpm --nodeps --force
如果安装时提示
./configure: error: the HTTP rewrite module requires the PCRE library.
安装openssl即可:
yum -y install openssl openssl-devel
如果提示需要PCRE包:
./configure: error: the HTTP rewrite module requires the PCRE library. You can either disable the module by using --without-http_rewrite_module option, or install the PCRE library into the system, or build the PCRE library statically from the source with nginx by using --with-pcre=<path> option.复制代码
需要进行安装:
yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel
配置Nginx转发到后端服务器/K8S/PaaS
worker_processes 1; user root; # 如果nginx没有权限写入到临时文件目录下可能会抛出异常,需要设置为root用户,或在目录下给nginx授权。 events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; # 以下几个字段为文件相关的,如果遇到413 Request Entity Too Large或500时需要配置 # nginx的异常可查看error.log进行定位 client_max_body_size 1000m; # 上传文件的最大值 client_body_buffer_size 100m; # 请求缓存区的大小 client_body_temp_path /tmp; # 临时文件存放目录,只有当上传的请求体超出缓存区大小时,才会写到临时文件中。 sendfile on; keepalive_timeout 65; server { listen 80; server_name localhost; location / { # nginx的转发配置 proxy_pass {PaaS应用的域名}; proxy_redirect off; } } }
