负载均衡 nginx的简介
是什么
Nginx是一个高性能的开源Web服务器和反向代理服务器。它的设计目标是为了解决C10k问题即在同一时间内支持上万个并发连接。
Nginx采用事件驱动的异步架构能够高效地处理大量并发请求同时占用较少的系统资源。它具有良好的扩展性和高可靠性广泛应用于大型网站和高负载的Web应用中。
nginx的特点以及功能 高性能Nginx采用异步非阻塞的处理方式可以高效地处理大量并发请求具有较低的内存消耗和CPU利用率。 反向代理Nginx可以作为反向代理服务器将客户端的请求转发给后端的多个服务器实现负载均衡和高可用性。 静态文件服务Nginx可以快速地提供静态文件的访问减轻动态应用服务器的负载。 动态反向代理Nginx可以通过配置动态反向代理规则将请求转发给不同的后端服务器实现灵活的请求处理和应用切换。 SSL/TLS支持Nginx支持HTTPS协议并提供了强大的SSL/TLS功能可以保护网站的安全性。 URL重写和重定向Nginx支持强大的URL重写和重定向功能可以通过配置简化URL结构和实现请求的重定向。 缓存和压缩Nginx支持静态文件的缓存和内容的压缩提高网站的性能和传输速度。 总之Nginx是一个高性能、可靠性强、功能丰富的Web服务器和反向代理服务器适用于各种规模的网站和应用场景。它的简单配置和灵活性使得它成为许多开发者和系统管理员的首选。 Nginx负载均衡
下载 输入命令 : cd /root/xyh/software 进入到资源文件目录 安装 Nginx 的4个依赖 输入命令 : yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel 安装完成后进行解压使用 输入命令 : tar -xvf nginx-1.13.7.tar.gz ( 解压 Nginx) 解压后进入其文件 命令 : cd nginx-1.13.7 编译执行配置: 考虑到后续安装ssl证书 添加两个模块 命令 : ./configure --with-http_stub_status_module --with-http_ssl_module 安装 进行安装 命令 : make make install 安装完后进入该目录 输入命令 : cd /usr/local/nginx 安装完后进入该目录 输入命令 : cd /usr/local/nginx 启动前安装 lsof 命令 输入命令 : yum install -y lsof 设置防火墙 开放 80 端口 输入命令 : firewall-cmd --zonepublic --add-port80/tcp --permanent 更新防火墙的端口并且查看已开放的端口 输入命令 : firewall-cmd --reload firewall-cmd --list-port # 启动 命令 : ./nginx #查看 命令 : lsof -i:80 在浏览器中输入虚拟机【Linux】-Centos的IP地址进行搜索 以上就是Nginx 的使用配置并且开启完成了
负载均衡 在资源文件夹中创建一个tomcat文件夹来存放Tomcat 输入命令 : mkdir tomcat 并且将tomcat服务解压到指定目录刚刚创建的tomcat文件夹中。 输入命令 : tar -xvf apache-tomcat-8.5.tar.gz -C tomcat 进入tomcat文件夹中 命令 : cd /root/xyh/software/tomcat 复制一个tomcat准备2个tomcat 命令 : cp -r apache-tomcat-8.5.20/ apache-tomcat-8.5.20_8081/ 查看命令 : ll 将其中的一个tomcat修改端口避免两个服务同时开启时端口被占用的情况。 命令 : cd apache-tomcat-8.5.20/conf 进入到tomcat的conf文件中 找到server.xml 文件进行修改端口 命令 : vim server.xml 编辑文件修改端口 修改之后的代码
