在CentOS7上源码安装OpenResty 1.9.5.1，

环境准备

您必须将这些库
perl 5.6.1+
libreadline
libpcre
libssl
安装在您的电脑之中。 对于 Linux来说, 您需要确认使用 ldconfig 命令，让其在您的系统环境路径中能找到它们。

• CentOS 7 安装OpenResty所需依赖

[root@snails ~]# yum -y install readline-devel pcre-devel openssl-devel gcc

构建 OpenResty

下载

从下载页 Download下载最新的ngx_openresty源码包，并且像下面的示例一样将其解压:

[root@snails ~]# wget https://openresty.org/download/openresty-VERSION.tar.gz
[root@snails ~]# tar xzvf ngx_openresty-VERSION.tar.gz

VERSION 的地方替换成您下载的源码包的版本号，比如说 1.9.15.1。

编译安装

然后在进入 ngx_openresty-VERSION/
目录, 然后输入以下命令配置:
./configure --prefix=/root/openresty

默认, --prefix=/usr/local/openresty
程序会被安装到/usr/local/openresty目录。
您可以指定各种选项，比如

[root@snails openresty-1.9.15.1]# ./configure --prefix=/opt/openresty \
                                              --with-luajit \
                                              --with-http_stub_status_module
gmake
gmake install

试着使用 ./configure --help 查看更多的选项。

设置环境变量及文件软链接

[root@snails ~]# ln -s /usr/local/openresty/nginx /usr/local/nginx
[root@snails ~]# vi /etc/profile
export ORPATH=/usr/local/openresty
export PATH=$PATH:$ORPATH/bin:$ORPATH/nginx/sbin

配置用户及组

[root@snails nginx]# groupadd -f www  
[root@snails nginx]# useradd -r -s /sbin/nologin -g www www
[root@snails nginx]# vi conf/nginx.conf
user www www;

验证

[root@snails nginx]# nginx
[root@snails nginx]# curl -I localhost
HTTP/1.1 200 OK

补充：
　　Nginx启动脚本/usr/lib/systemd/system/nginx.service
