Linux下nginx的安装
安装环境：
# cat /proc/version
Linux version 3.10.0-123.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC) ) #1 SMP Mon Jun 30 12:09:22 UTC 2014
# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
yum安装
设置yum仓库地址
vi /etc/yum.repos.d/nginx.repo：[nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=1 enabled=1 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true
使用yum安装：
yum install -y nginx
安装完成后配置文件所在目录为/etc/nginx。
- nginx的启动与停止：
- 启动nginx：
nginx或systemctl start nginx。 - 停止nginx：
nginx -s stop或systemctl stop nginx。
查看nginx是否启动成功。
ps -ef|grep nginx

访问网站
http://localhost/。卸载nginx。
yum list nginx

源码安装
源码安装的方式方便对nginx进行自定义的配置以及安装插件。
下载源码，下载地址：http://nginx.org/en/download.html，这里使用的版本为`nginx-1.18.0.tar.gz`。
解压
nginx-1.18.0.tar.gz：tar xf nginx-1.18.0.tar.gz
安装可能需要的依赖：
yum -y install autoconf automake make
yum -y install gcc gcc-c++
yum -y install pcre pcre-devel
yum -y install zlib zlib-devel
yum install -y openssl openssl-devel
配置：
cd nginx-1.18.0
./configure
安装：
make && make install
安装完成后的二进制文件和配置文件在/usr/local/nginx目录下。
配置环境变量：
vi /etc/profile
最后增加 export PATH=$PATH:/usr/local/nginx/sbin
source /etc/profile
安装成为服务：
vi nginx.service

OpenResty的安装
OpenResty是一个基于Nginx与Lua的高性能Web平台，其内部集成了大量精良的Lua库、第三方模块以及大多数的依赖项。
下载OpenResty，下载地址：
https://openresty.org/download/openresty-1.17.8.2.tar.gz。安装：
tar xf openresty-1.17.8.2.tar.gz
cd openresty-1.17.8.2
./configure
make && make install
配置环境变量：
vi /etc/profile
最后追加 export PATH=$PATH:/usr/local/openresty/bin
cd /usr/local/openresty/bin
ll | grep openresty
lrwxrwxrwx. 1 root root 37 Oct 9 14:09 openresty -> /usr/local/openresty/nginx/sbin/nginx
openresty是一个指向/usr/local/openresty/nginx/sbin/nginx的软链接，其实openresty内置了一个nginx，使用方法与nginx一样。
