腾讯云centos7 环境搭建（2）nginx安装

安装

yum install nginx

安装之后，可以查看nginx的默认安装目录

[root@VM_0_9_centos ~]# whereis nginx
nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man3/nginx.3pm.gz /usr/share/man/man8/nginx.8.gz

以下是Nginx的默认路径：

(1) Nginx配置路径：/etc/nginx/
(2) PID目录：/var/run/nginx.pid
(3) 错误日志：/var/log/nginx/error.log
(4) 访问日志：/var/log/nginx/access.log
(5) 默认站点目录：/usr/share/nginx/html

事实上，只需知道Nginx配置路径，其他路径均可在/etc/nginx/nginx.conf 以及/etc/nginx/conf.d/default.conf 中查询到

设置自动启动

# 设置自动启动
systemctl enable nginx

[root@VM_0_9_centos nginx]# systemctl enable nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service

# 启动nginx
systemctl start nginx

nginx配置

在真实的环境中，通常一个nginx会有多个站点的配置，如果所有站点的配置信息都放在nginx.conf中那将非常不便于管理和维护，为此我们可以将每个站点的配置信息放在单独的文件中，然后在nginx中include进来。
然后编辑nginx.conf为如下内容

user nginx;
worker_processes auto;

error_log /var/log/nginx/error.log;

pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
#include /usr/share/nginx/modules/*.conf;
