Nginx配置

1.root和alias

server {

    listen 8000;

    # 1.root配合index使用：会吧/test_1拼接到网址前面
    location /test_1 {
        root /etc/nginx/my_html;
        index index.html;
    }

    # 2.alias配合index使用：会吧/test_2拼接到网址后面
    location /test_2 {
        alias /etc/nginx/my_html;
        index index.html;
    }
}

2.反向代理

# nginx代理服务器
server {

    listen 8000;

    location / {
        # 要被代理的服务器地址
        proxy_pass http://127.0.0.1:8001;
    }
}

# 真实的服务器
server {

    listen 127.0.0.1:8001;

    location / {
        root /etc/nginx/my_html;
        index index.html;
    }
}

3.负载均衡

# 负载均衡
upstream fuzaijunheng {
    # 1.默认的转发规则-轮询
    # server 127.0.0.1:8001;
    # server 127.0.0.1:8002;

    # 2.加权轮询(权值默认为1)
    # server 127.0.0.1:8001;
    # server 127.0.0.1:8002 weight=2;

    # 3.请求第一次时那台服务器,以后就是那套服务器
    ip_hash;
    server 127.0.0.1:8001;
    server 127.0.0.1:8002;

}

# nginx服务器
server {
    listen 8000;

    location / {
        # 负载均衡的名字
        proxy_pass http://fuzaijunheng;
    }
}

# 真实服务器1
server {
    listen 127.0.0.1:8001;

    location / {
        root /etc/nginx/my_html;
        index index_1.html;
    }
}

# 真实服务器2
server {
    listen 127.0.0.1:8002;

    location / {
        root /etc/nginx/my_html;
        index index_2.html;
    }
}
