Nginx 安装 配置 使用

nginx安装：

>本文采用编译安装的方式

1. 解决依赖关系 
   编译安装nginx需要事先需要安装开发包组”Development Tools”和 “Development Libraries”。同时，还需要专门安装pcre-devel包：

    yum -y install zlib zlib-devel openssl openssl-devel pcre-devel gd-devel
   

2. 添加用户

   groupadd -r nginx
   useradd -r -g nginx nginx
   

3. 编译安装

   ./configure \
   --prefix=/usr \
   --sbin-path=/usr/sbin/nginx \
   --conf-path=/etc/nginx/nginx.conf \
   --error-log-path=/var/log/nginx/error.log \
   --http-log-path=/var/log/nginx/access.log \
   --pid-path=/var/run/nginx.pid \
   --lock-path=/var/run/nginx.lock \
   --http-client-body-temp-path=/var/cache/nginx/client_temp \
   --http-proxy-temp-path=/var/cache/nginx/proxy_temp \
   --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp \
   --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp \
   --http-scgi-temp-path=/var/cache/nginx/scgi_temp \
   --user=nginx \
   --group=nginx \
   --with-http_ssl_module \
   --with-http_realip_module \
   --with-http_addition_module \
   --with-http_sub_module \
   --with-http_dav_module \
   --with-http_flv_module \
   --with-http_mp4_module \
   --with-http_gunzip_module \
   --with-http_gzip_static_module \
   --with-http_random_index_module \
   --with-http_secure_link_module \
   --with-http_stub_status_module \
   --with-http_auth_request_module \
   --with-mail \
   --with-mail_ssl_module \
   --with-file-aio \
   --with-ipv6 \
   --with-http_v2_module \
   --with-http_image_filter_module \
   --with-pcre \
   --with-cc-opt='-O2 -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic'
   make
   make install
   

4. 配置支持Centos7 systemctl服务管理

   vim /lib/systemd/system/nginx.service
   

   添加下面内容

   [Unit]
   Description=The NGINX HTTP and reverse proxy server
   After=syslog.target network.target remote-fs.target nss-lookup.target
   
   [Service]
   Type=forking
   PIDFile=/var/run/nginx.pid
   ExecStartPre=/usr/sbin/nginx -t
   ExecStart=/usr/sbin/nginx
   ExecReload=/bin/kill -s HUP $MAINPID
   ExecStop=/bin/kill -s QUIT $MAINPID
   PrivateTmp=true
   
   [Install]
   WantedBy=multi-user.target
   

   可以通过systemctl status start stop来看nginx服务内容

5. 配置nginx

   vim /etc/nginx/nginx.conf
   
   #在http节点下，添加upstream节点
   
   upstream mysite {
       server 172.20.13.229:8081;
       server 172.20.13.230:8082;
   }
   
   #修改server节点下的location节点
   
   location / {
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_buffering off;
           proxy_pass http://mysite;
       }
   
   #主要内容在mysite中
