nginx+tomcat负载均衡

nginx版本为1.9.15

必须关闭selinux,否则做请求转发时会失败报错

2016/06/22 17:11:19 [crit] 3103#3103: *1 connect() to 192.168.111.130:8080 failed (13: Permission denied) while connecting to upstream, client: 192.168.111.1, server: localhost, request: "GET /docs/ HTTP/1.1", upstream: "http://192.168.111.130:8080/docs/",
host: "192.168.111.129"

关闭selinux

执行 setenforce 0

这个之后暂时关闭selinux,重启后selinux还是开启的，要永远关闭selinux需修改配置文件

vi /etc/selinux/config

将SELINUX设置为disabled

修改nginx配置文件

新建/etc/nginx/conf.d/upstream.conf

内容如下

upstream localhost {
#ip_hash;
server 192.168.111.129:8080;
server 192.168.111.130:8080;

}

修改/etc/nginx/conf.d/default.conf

server {

    listen       80;

    server_name  localhost;

    #charset koi8-r;

    #access_log  /var/log/nginx/log/host.access.log  main;

    location / {

        root   /usr/share/nginx/html;

        index  index.html index.htm;
proxy_pass http://localhost;
    }

    #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   /usr/share/nginx/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;

    #}

}

增加server_name  localhost;

location/下增加proxy_pass http://localhost;
重启nginx
