一台最小化安装的 CentOS 7.3 虚拟机

安装 nginx 依赖包

yum install -y pcre-devel zlib-devel openssl-devel wget gcc tree vim

Nginx 依赖于 pcre、zlib、openssl, 在编译前配置时如果有问题
可以使用 yum 方式安装三个包（pcre-devel、zlib-devel、openssl-devel）

使用本地主机访问虚拟机上的 Nginx 服务器

停止 Nginx 的三种方式

# 1. 立即停止 Nginx 服务
/usr/local/nginx/sbin/nginx -s stop

# 2. 完成当前任务后停止
/usr/local/nginx/sbin/nginx -s quit

# 3. 杀死 Nginx 进程
killall nginx

使用软连接将 nginx 链接到/usr/local/sbin

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin
ll /usr/local/sbin/ | grep “nginx”

引用.bash_profile 文件

source ~/.bash_profile

使用 nginx 命令

# 启动 nginx

nginx

# 停止 nginx

nginx -s quit

把 `nginx` 命令添加到系统服务

创建并编辑文件/root/service-nginx.sh

#!/bin/sh
