1. 环境搭建

1.1 编译

# 下载代码
git clone git@192.168.128.110:chromium/nginx.git nginx-1.22.0
或
git clone https://192.168.128.110/chromium/nginx.git nginx-1.22.0
# 生成makefile
cd nginx-1.22.0

# 编译
make -j4
# 安装
make install
# 创建nginx临时目录
mkdir -p /var/cache/nginx
# debug版本
编译选项：--with-debug
配置文件
master_process  off;
daemon          off;

1.2 配置

upstream设置：

• 轮询【默认】：每次请求都会切换server，同一个session会在多个服务器上切换
• ip_hash：hash算法会导致同一网段都在一个server上，不均衡

负载均衡配置：

#user  nobody;
worker_processes  4;
events {
    # 最大并发数
    worker_connections  1024;
}
http {
    # 将nginx版本号隐藏掉
    server_tokens off;
    # 待选服务器列表
    upstream myproject {
        # ip_hash指令，将同一用户引入同一服务器。
        ip_hash;
        server 10.0.32.159:80;
        server 10.0.32.169:80;
    }
    server{
                # 监听端口
                listen 80;
                # 根目录下
                location / {
                    # 选择哪个服务器列表
                    proxy_pass http://myproject;
                }
            }
}

1.3 启动

# 启动
nginx
# 停止
nginx -s stop
# 重启
nginx -s reload
