【Nginx】编译安装(Centos)

下载编译包

https://nginx.org/download/nginx-1.24.0.tar.gz

解压： tar -zxvf nginx-1.24.0.tar.gz

进入目录: nginx-1.24.0

配置

./configure --with-http_ssl_module --with-http_v2_module --with-http_gzip_static_module

如果不加扩展模块就直接执行: ./configure

提示缺少：rewrite

./configure: error: the HTTP rewrite module requires the PCRE library

安装: sudo yum install pcre pcre-devel

提示缺少： OpenSSL

./configure: error: SSL modules require the OpenSSL library.
You can either do not enable the modules, or install the OpenSSL library
into the system, or build the OpenSSL library statically from the source
with nginx by using --with-openssl=<path> option.

然后安装:

yum install openssl

yum install openssl-devel

然后执行：

./configure --with-http_ssl_module --with-http_v2_module --with-http_gzip_static_module

成功了：

creating objs/Makefile （生成了编译配置文件，）

确保安装了gcc，然后

make

查看安装目录

whereis nginx

启动

cd /usr/local/nginx/sbin/

./nginx

启动结果

ps -aux | grep nginx

[root@master01 sbin]# ./nginx
[root@master01 sbin]# ps -aux | grep nginx
root 30808 0.0 0.0 46136 956 ? Ss 17:33 0:00 nginx: master process ./nginx
nobody 30809 0.0 0.0 48672 3780 ? S 17:33 0:00 nginx: worker process
root 30828 0.0 0.0 112820 2308 pts/2 S+ 17:33 0:00 grep --color=auto nginx

Nginx 在启动时，默认情况下会使用一个主进程（master process）和多个工作进程（worker processes）。主进程通常以 root 用户权限运行，以便能够绑定到特权端口（如 80 和 443），而工作进程则通常以一个非特权用户（如 nobody）的身份运行，以提高安全性。

如何更改工作进程的用户

vi /etc/nginx/nginx.conf

把： user nobody; 改成xxxx 然后启动后就是 woker进程就是xxx用户组
