CentOS7.x 基于源码构建安装openresty
参考：
https://openresty.org/en/installation.html
https://openresty.org/en/installation.html#building-openresty
1.前期依赖库安装：
yum install -y make cmake gcc curl
yum install -y prel pcre-devel
yum install -y openssl openssl-devel
# mkdir -p /opt/software/openresty
2.下载：
# wget https://openresty.org/download/openresty-1.17.8.2.tar.gz
3.解压：
# tar -zxvf openresty-1.17.8.2.tar.gz -C /opt/software/openresty/
# cd /opt/software/openresty/openresty-1.17.8.2/
4.编译：
# ./configure --prefix=/usr/local/openresty
默认, --prefix=/usr/local/openresty 程序会被安装到/usr/local/openresty目录。

编译成功提示：
Type the following commands to build and install:
gmake
gmake install
也可以携带模块参数等安装，如：
# ./configure --prefix=/usr/local/openresty --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module
5.安装：
# make -- 还可以根据CPU核数添加 j参数，比如两核：j2
# sudo make install
sed -e "s|%%PREFIX%%|/usr/local/openresty/nginx|" \
环境变量：
export PATH=/usr/local/openresty/bin:/usr/local/openresty/nginx/sbin:$PATH
官方建议：
# better also add the following line to your ~/.bashrc or ~/.bash_profile file.
export PATH=/usr/local/openresty/bin:$PATH
6.配置：
cd /usr/local/openresty/nginx/conf
vim nginx.conf
或者直接：vim /usr/local/openresty/nginx/conf/nginx.conf
开放root权限，在文件顶部添加：user root root;
查看版本：
# /usr/local/openresty/bin/openresty -V
nginx version: openresty/1.17.8.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)
built with OpenSSL 1.0.2k-fips 26 Jan 2017

7.启动：
# /usr/local/openresty/bin/openresty
查看启动进程：ps aux |grep openresty
