1. 下载安装nginx
注意 因为stream 并不是 nginx自带的module 所以需要 在安装是 通过 --with 的方式增加上.
下载必要的程序包
# openssl wget https://www.openssl.org/source/openssl-1.1.1c.tar.gz #zilib wget http://www.zlib.net/zlib-1.2.11.tar.gz #pcre wget https://netix.dl.sourceforge.net/project/pcre/pcre/8.40/pcre-8.40.tar.gz #nginx wget http://nginx.org/download/nginx-1.17.3.tar.gz
2. 解压缩
tar -zxvf xxxx.tar.gz
3. 分别进行安装
1. 首先 使用 tar 包 安装上 zlib openssh 以及 pcre 三个包 Firest 进入解压缩好的目录 ./configure or ./config second make && make install 2. 进行安装nginx #进入nginx 的目录 执行配置. ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --with-http_gzip_static_module --with-stream --with-stream_ssl_module # 注意 stream 就可以进行 TCP层的反向代理了. 参考网站:https://blog.csdn.net/jijiuqiu6646/article/details/78675891
4. 问题解决.
打开nginx 时会报错 如下: [[email protected] sbin]# ./nginx ./nginx: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory [[email protected] sbin]# openssl version openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory
解决方法为:
参考网站: https://blog.csdn.net/caohongshuang/article/details/78031978 查看 依赖关系ldd $(which /usr/local/nginx/sbin/nginx)
[[email protected] sbin]# ldd $(which /usr/local/nginx/sbin/nginx)
linux-vdso.so.1 => (0x00007ffe6b5f2000)

进入到openssl 相关的目录 进行 软连接处理
[[email protected] sbin]# cd /usr/local/lib64/
[[email protected] lib64]# ll

[[email protected] lib64]# ln libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1
5. 修改nginx配置文件.
注意 第三步 nginx的 configure 时有一个配置简述 Configuration summary + using system PCRE library + using system OpenSSL library + using system zlib library nginx path prefix: "/usr/local/nginx" nginx binary file: "/usr/local/nginx/sbin/nginx" nginx modules path: "/usr/local/nginx/modules" nginx configuration prefix: "/usr/local/nginx/conf" nginx configuration file: "/usr/local/nginx/conf/nginx.conf" nginx pid file: "/usr/local/nginx/logs/nginx.pid" nginx error log file: "/usr/local/nginx/logs/error.log" nginx http access log file: "/usr/local/nginx/logs/access.log" nginx http client request body temporary files: "client_body_temp" nginx http proxy temporary files: "proxy_temp" nginx http fastcgi temporary files: "fastcgi_temp" nginx http uwsgi temporary files: "uwsgi_temp" nginx http scgi temporary files: "scgi_temp"
这里面就可以看到配置文件的位置了. 进行修改可以.
vim /usr/local/nginx/conf/nginx.conf
增加上与 http 同级的配置节:
stream{
server {
listen 1433;
proxy_pass 10.24.14.56:1433;
}
}
# 注意 第一点 需要有 分号 我经常忘记
# 第二点 大括号要处理好.
如果 80 端口已经使用的花 可以在http 里面讲 80端口修改一下就可以了.
6. 启动以及验证
/usr/local/nginx/sbin/nginx -s reload
7. 验证负载均衡
修改配置节的内容:
stream{
upstream zhaobsh{
server 10.24.14.56:1433;
server 10.24.210.11:1433;
}
server {
listen 1433;
proxy_pass zhaobsh;
}
}
验证效果为:
