Linux源码安装nginx实现负载均衡

环境：Ubuntu16.04 amd64

nginx实现负载均衡

源码安装

1.下载解压

wget http://nginx.org/download/nginx-1.12.0.tar.gz
tar zxvf nginx-1.12.0.tar.gz

2.配置安装路径

cd nginx-1.12.0
./configure --prefix=/opt/nginx // 此步骤报错可能是没有相应的C编译器等，需要先安装依赖包，如果成功，则跳过步骤3
//如果需要ssl使用
./configure --with-http_stub_status_module --with-http_ssl_module  --with-http_realip_module
// 如果需要rtmp，使用
./configure --add-module=/root/nginx-rtmp-module
// 包含https
./configure --prefix=/opt/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-http_auth_request_module --with-http_addition_module --with-http_dav_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_v2_module --with-http_sub_module --with-stream --with-stream_ssl_module

3.安装依赖包

sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get install gcc  zlib1g-dev
可选：sudo apt-get install openssl libssl-dev

如果报错E: Unable to locate package pcre-devel可能源问题，可以更换为其他源，这里选择阿里源
在/etc/apt/sources.list中替换为

    deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse  
    deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse  
    deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse  
    deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse  
    ##测试版源  
    deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse  
    # 源码  
    deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse  
    deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse  
    deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse  
    deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse  
    ##测试版源  
    deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse  
    # Canonical 合作伙伴和附加  
    deb http://archive.canonical.com/ubuntu/ xenial partner  
    deb http://extras.ubuntu.com/ubuntu/ xenial main

完成后重新执行步骤2的命令
4.编译

make
// 没有的话，先安装sudo apt-get install make

5.完成安装

sudo make install

快速安装

sudo apt-get update
sudo apt-get install nginx

最后在nginx配置文件中实现负载均衡

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;
# 负载均衡
    upstream nginxBalance {
#  将同一会话定向到同一个服务器
        ip_hash;
        server 10.211.55.9:9090;
        server 10.211.55.10:9090;
    }
    server {
        listen       8080;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass http://nginxBalance;
        }
    }
}
