Centos7安装部署NGINX,做反向代理
时间:2022-10-14 00:04 作者:Anglei 分类: Linux
gcc 安装
安装 nginx 需要先将官网下载的源码进行编译,编译依赖 gcc 环境,如果没有 gcc 环境,则需要安装。
yum install gcc-c++
PCRE pcre-devel 安装
PCRE(Perl Compatible Regular Expressions)是一个Perl库,包括 perl 兼容的正则表达式库。nginx 的 http 模块使用 pcre 来解析正则表达式,所以需要在 linux 上安装 pcre 库,pcre-devel 是使用 pcre 开发的一个二次开发库。nginx也需要此库。
yum install -y pcre pcre-devel
zlib 安装
zlib 库提供了很多种压缩和解压缩的方式, nginx 使用 zlib 对 http 包的内容进行 gzip ,所以需要在 Centos 上安装 zlib 库。
yum install -y zlib zlib-devel
OpenSSL 安装
OpenSSL 是一个强大的安全套接字层密码库,囊括主要的密码算法、常用的密钥和证书封装管理功能及 SSL 协议,并提供丰富的应用程序供测试或其它目的使用。nginx 不仅支持 http 协议,还支持 https(即在ssl协议上传输http),所以需要在 Centos 安装 OpenSSL 库。
yum install -y openssl openssl-devel
二、安装Nginx
# 下载源码包
cd /opt
wget http://nginx.org/download/nginx-1.15.9.tar.gz
# 解压缩源码
tar -xzvf nginx-1.15.9.tar.gz
# 配置,编译安装(开启nginx状态监测功能)
cd nginx-1.15.9/
./configure --prefix=/opt/nginx --with-http_ssl_module --with-http_stub_status_module --with-stream
make && make install
# 启动nginx,进入sbin目录,找到nginx启动命令
./nginx # 开启niginx
./nginx -s stop # 相当于先查出nginx进程id再使用kill命令强制杀掉进程
./nginx -s quit # 待nginx进程处理任务完毕进行停止
./nginx -s reload # 重新加载配置
开启防火墙80端口的外部访问:
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload
启动成功后,在浏览器输入服务器IP,就可以看到这样的页面了:
设置开机自启
在 rc.local 添加启动代码即可:
vim /etc/rc.local
在最后一行添加:
/opt/nginx/sbin/nginx
设置文件的执行权限:
chmod 755 /etc/rc.local
至此,nginx就安装完毕了。除此之外,也可以设置nginx为服务并开机自启,具体请自行解决。
对nginx.conf进行修改,以支持反向代理
