5,Centos7编译安装nginx并设置反向代理

一、编译部署Nginx 1.12

安装配置：

[root@localhost ~]# groupadd nginx
[root@localhost ~]# useradd -s /sbin/nologin -g nginx -M nginx
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
#关掉selinux
#服务器文件描述符等

[root@localhost ~]# yum install gcc gcc-c++ glibc automake pcre zlip zlib-devel openssl-devel pcre-devel wget lrzsz
[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# wget http://nginx.org/download/nginx-1.12.0.tar.gz
[root@localhost src]# tar -zxvf nginx-1.12.0.tar.gz
[root@localhost src]# cd nginx-1.12.0
[root@localhost nginx-1.12.0]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module  --with-pcre
[root@localhost nginx-1.12.0]# make
[root@localhost nginx-1.12.0]# make install

备注：

--prefix：Nginx安装目录
--user：Nginx用户
--group：Nginx用户所属组
--with-http_ssl_module：提供https支持
--with-http_flv_module：搭建flv视频服务器使用的
--with-http_stub_status_module：开启Stub Status模块，该模块会产生一个服务器状态和信息页
--with-http_gzip_static_module：开启Gzip静态模块，该模块用于发送预压缩文件
--with-pcre：perl执行文件路径

配置服务：

[root@localhost nginx-1.12.0]# vi /usr/lib/systemd/system/nginx.service
[Unit]
Description=The nginx HTTP and reverse proxy server
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking  
PIDFile=/usr/local/nginx/logs/nginx.pid  
ExecStartPre=/usr/bin/rm -f /run/nginx.pid  
ExecStartPre=/usr/local/nginx/sbin/nginx -t  
ExecStart=/usr/local/nginx/sbin/nginx  
ExecReload=/bin/kill -s HUP $MAINPID  
KillMode=process  
KillSignal=SIGQUIT  
TimeoutStopSec=5  
PrivateTmp=true
[Install]
WantedBy=multi-user.target

验证：

[root@localhost nginx-1.12.0]# chmod a+x /usr/lib/systemd/system/nginx.service
[root@localhost nginx-1.12.0]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@localhost nginx-1.12.0]# systemctl start nginx
[root@localhost nginx-1.12.0]# ps -ef | grep nginx
root      24412      1  0 16:31 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nginx     24413  24412  0 16:31 ?        00:00:00 nginx: worker process
root      24415  10541  0 16:31 pts/0    00:00:00 grep --color=auto nginx

访问：

http://192.168.146.136

二、nginx配置反向代理

设置nginx配置文件，并include proxy.conf文件：

[root@localhost conf]# cat nginx.conf
    server {
        listen       80;
        server_name  localhost;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location / {
            root   html;
            proxy_pass    http://127.0.0.1:7777;
            include    proxy.conf;
        index  index.php index.html index.htm;
        }
        
        #以下三行好像不用加
        location ~ .*.(js|css|jpg|png)$ {
             proxy_pass http://127.0.0.1:7777;
        }
        ****************

备注：如果只加proxy_pass一行信息，可能会造成页面能访问，但是css等样式文件加载不出来，只能显示文字信息。

proxy.conf配置文件：

[root@localhost conf]# cat proxy.conf
# proxy.conf
client_body_buffer_size     256k;
client_body_temp_path       client_body 1 2;
client_max_body_size        50m;
proxy_buffers               4 32k;
proxy_buffer_size           4k;
proxy_busy_buffers_size     64k;
proxy_connect_timeout       30;
proxy_read_timeout          60;
proxy_redirect              off;
proxy_send_timeout          30;
proxy_set_header            Host $host;
proxy_set_header            X-Server-Addr $server_addr;
proxy_set_header            X-Remote-Addr $remote_addr;
proxy_set_header            X-Remote-Port $remote_port;
proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header            X-Forwarded-Port $server_port;
proxy_set_header            X-Forwarded-Proto $scheme;
proxy_set_header            Server-Type nginx;
proxy_temp_file_write_size  64k;
proxy_temp_path             proxy_temp 1 2;
proxy_max_temp_file_size    128m;
proxy_next_upstream         error timeout invalid_header http_500 http_503 http_404;

重启nginx服务：

[root@localhost conf]# systemctl stop nginx
[root@localhost conf]# systemctl start nginx
