nginx负载均衡配置

4etfeww

1、准备工作
nginx-1.6.0.tar.gz
httpd-2.2.23.tar.gz

Director Server：10.0.2.201
Real Server：10.0.2.203
Real Server：10.0.2.204

2、Director Server上配置nginx

# yum install -y pcre pcre-devel
# tar zxvf nginx-1.6.0.tar.gz
# cd nginx-1.6.0
# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_gzip_static_module
# make && make install

3、配置nginx的反向代理
# vim /usr/local/nginx/conf/nginx.conf
修改server_name为域名或者IP地址，并添加以下内容
location / {
            proxy_pass http://10.0.2.204;
            root   html;
            index  index.html index.htm;
}
# /usr/local/nginx/sbin/nginx

4、配置nginx负载均衡
# vim /usr/local/nginx/conf/nginx.conf
upstream myserver{
server 10.0.2.203:80 weight=1;
server 10.0.2.204:80 weight=1;
ip_hash;
location / {
proxy_pass http://myserver;
proxy_next_upstream http_500 http_502 http_503 error timeout invalid_header;
include /usr/local/nginx/conf/proxy.conf;

# vim /usr/local/nginx/conf/proxy.conf
proxy_redirect off;
proxy_set_header Host $host;#
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
# /usr/local/nginx/sbin/nginx

5、Real Server安装http
# tar zxvf httpd-2.2.23.tar.gz
# cd httpd-2.2.23
# ./configure --prefix=/usr/local/apache2
# make && make install
# cp /usr/local/apache/bin/apachectl /etc/init.d/httpd
# vim /etc/init.d/httpd
修改文件，在文件中'#!/bin/sh'后面加入下面两条规则：
#!/bin/sh
#
# chkconfig: 2345 85 15
# description: Apache is a World Wide Web Server
#
# chkconfig --add httpd
# chkconfig --list httpd
# service httpd start
