目标

• Ubuntu 18.04
• OpenResty 1.19.3.2

安装依赖

• 启用 HTTP 基本状态模块：--with-http_stub_status_module
• 启用 HTTP gzip 静态文件压缩模块：--with-http_gzip_static_module
• 启用 HTTP/2 模块：--with-http_v2_module

sudo apt-get update -y
sudo apt-get install -y libpcre3-dev \
  libssl-dev \
  perl \
  make \
  build-essential \
  curl \
  zlib1g-dev

下载 OpenResty

cd /opt
sudo curl -LO https://openresty.org/download/openresty-1.19.3.2.tar.gz
tar zxf openresty-1.19.3.2.tar.gz

安装 OpenResty

# 配置
./configure \
  --with-http_gzip_static_module \
  --with-http_v2_module \
  --with-http_stub_status_module
# 编译
make
# 安装
sudo make install

使用 systemd 管理 OpenResty 服务

编写 Service 文件：在 /usr/lib/systemd/system 目录下创建一个 openresty.service 文件，

# 如果没有目录，需要创建
sudo mkdir /usr/lib/systemd/system
# 创建文件：
vim /usr/lib/systemd/system/openresty.service

文件内容如下：

# Stop dance for OpenResty
# =========================
#
# ExecStop sends SIGSTOP (graceful stop) to OpenResty's nginx process.
# If, after 5s (--retry QUIT/5) nginx is still running, systemd takes control
# and sends SIGTERM (fast shutdown) to the main process.
# After another 5s (TimeoutStopSec=5), and if nginx is alive, systemd sends
# SIGKILL to all the remaining processes in the process group (KillMode=mixed).
#
# nginx signals reference doc:
# http://nginx.org/en/docs/control.html
