前言:
而今我们对“keepalivednginx详解”大致比较着重,各位老铁们都想要分析一些“keepalivednginx详解”的相关内容。那么小编也在网上搜集了一些对于“keepalivednginx详解””的相关资讯,希望小伙伴们能喜欢,姐妹们快快来了解一下吧!一、准备工作
先安装 pcre pcre-devel openssl openssl-devel
二、nginx安装
./configure --user=YEYIBOY --group=YEYIBOY --prefix=/usr/local/nginx1.18 --with-http_stub_status_module --with-http_ssl_module
Make
Make install
/usr/local/nginx1.6.2/sbin/nginx -t 检查语法
三、编辑配置文件
打开 cd /usr/local/nginx/conf/
编辑sudo vim nginx.conf
在http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65;下面增加
Upstream backend {
ip_hash; 使同一主机始终登录同一台机器
Server 192.168.160.154:80 max_fails=3 fail_timeout=30;
Server 192.168.160.155:80 max_fails=3 fail_timeout=30;
}
server {
listen 80;
server_name yeyiboy.com;
index index.html index.htm;
location / {
proxy_pass ; (外部主机来访问时,通过负载均衡器,采用轮询,平均抛给上面的192.168.160.154 192.168.160.155 主机)
proxy_set_header Host $host; (假设一台机器设置多个服务网站时,为了域名不混乱,应加这行和下行)
proxy_set_header X-Forwarded-For $remote_addr;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
主 vim /usr/local/nginx/extra/upstream01.conf
Upstream blog_real servers {
Server 10.0.0.17:80 weight=5;(权重)
Server 10.0.0.18:80 weight=5;
Server 10.0.0.19:80 weight=5;
可以去掉权重加 ip_hash;
url_hash 用在缓存服务器
}
Server { listen 80;
Server_name blog.etiantian.org;
Local / { proxy_pass ; }
}
Cd nginx.conf 添加 include extra/upstream01.conf
备:复制上面内容
Nginx支持的代理方式:proxy_pass fastcgi_pass memcached_pass
Upstream 模块应放在nginx.conf配置里的http{ }标签内
Location设置URI转发 语法: location [ =|~|~*|^~] uri {…….}
[=] 精确匹配
[~] 区分大小写
[^~] 只匹配字符串,不匹配正则表达式
[~*] 不区分大小写
[@] 指定一个命名的location 一般只用于内部重定向请求
http_proxy_module 从一台转发到另一台
proxy_set_header XForwarded-For $remote_addr 让web服务器记录用户IP
proxy_set_header Host $host 查找主机
proxy_next_upstream 健康检查
nginx 四层负载均衡配置 (events与http之间添加图中涂黄部分)
cd /usr/local/nginx1.12
./confgure --prefix=/usr/local/nginx --with-stream
make
make install
vim /usr/local/nginx/conf/nginx.conf
events {
worker_connections 1024; }
stream {
upstream mysite { server 192.168.1.1:8080; }
server { listen 3306; proxy_pass mysite; } }
http {
include mime.types;
default_type application/octet-stream;
Keepalived+nginx配置
Keepalived配置
sudo vim /etc/keepalived/keepalived.conf
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 150
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.1.254/24
192.168.1.253/24
}
}
Nginx配置
Sudo vim /usr/local/nginx/conf/nginx.cong
upstream {
#ip_hash;
server 192.168.1.135:80 max_fails=3 fail_timeout=30;
server 192.168.1.138:80 max_fails=3 fail_timeout=30;
}
upstream blog.yeyiboy.com{

server 192.168.1.135:80 max_fails=3 fail_timeout=30;
server 192.168.1.138:80 max_fails=3 fail_timeout=30;
}
upstream bbs.yeyiboy.com{

server 192.168.1.138:80 max_fails=3 fail_timeout=30;
}
server {
listen 80;
server_name yeyiboy.com;
location / {
root html;
index index.html index.htm index.php;
proxy_pass ;
}
}
server {
listen 80;
server_name blog.yeyiboy.com;

proxy_pass ;
}
}
server {
