一. 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++
二. 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。命令:
yum install -y pcre pcre-devel
三. 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
四. 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
官网下载
1.直接下载.tar.gz
安装包,地址:https://nginx.org/en/download.html
wget -c https://nginx.org/download/nginx-1.20.0.tar.gz
tar -zxvf nginx-1.20.1.tar.gz
mv nginx-1.20.1 nginx 改名字
使用默认配置:
./configure
make
make install
cd /usr/local/nginx/sbin/
./nginx
./nginx -s stop
./nginx -s quit
./nginx -s reload
ps aux|grep nginx 查看进程
先停止再启动(推荐):
对 nginx 进行重启相当于先停止再启动,即先执行停止命令再执行启动命令。如下:
./nginx -s quit
./nginx
2.重新加载配置文件:
当 ngin x的配置文件 nginx.conf 修改后,要想让配置生效需要重启 nginx,使用-s reload
不用先停止 ngin x再启动 nginx 即可将配置信息在 nginx 中生效,如下:
./nginx -s reload
启动成功后,在浏览器可以看到这样的页面:
系统下怎么配置多个conf文件。
step 1:在nginx.conf文件所在目录新建conf.d目录,即mkdir conf.d,为确保权限能够访问到,so chmod 777 conf.d
step 2:编辑nginx.conf文件,内容为:
include /usr/local/nginx/conf/conf.d/*.conf;
step 3:在conf.d目录下随便写个.conf文件, 内容为:
server{
listen 8888;
server_name localhost;
location / {
root /usr/local/nginx/html;
index index.html index.htm;
}
}

conf.d 下的目录
test.conf,ntest.conf
server{ listen 8001; server_name localhost; location / { proxy_pass http://test_server; } } upstream test_server{ server 192.168.0.55:8002; server 192.168.0.55:8003; } server{ listen 9001; server_name localhost; location / { proxy_pass http://ntest_server; } } upstream ntest_server{ server 192.168.0.55:9002; server 192.168.0.55:9003; }
