# nginx_build_script is spin-off from [minoplhy/nginquic](https://github.com/minoplhy/nginquic)@ModSecurity_incl branch.

The script here is entirely copied from [minoplhy/nginquic](https://github.com/minoplhy/nginquic)@ModSecurity_incl. Which included ModSecurity for my own using.

```bash
export Nginx_Install=yes  # This variable is required if you want Nginx to be installed scriptibly (on Debian-based systems).
curl https://raw.githubusercontent.com/minoplhy/scriptbox/main/nginx_build_script/build.sh > ~/nginx_scriptbox.sh
bash ~/nginx_scriptbox.sh
```
new way to run! :
```bash
# With install Nginx
curl https://raw.githubusercontent.com/minoplhy/scriptbox/main/nginx_build_script/build.sh | bash -s -- --install
```

# Arguments
```bash
while [ ${#} -gt 0 ]; do
    case "$1" in
        --no-modsecurity | -nm )            DISABLE_MODSECURITY=true;;  # Not include ModSecurity in building
        --no-lua | -nl )                    DISABLE_LUA=true        ;;  # Not include Lua in building
        --install | -i )                    INSTALL=true            ;;  # Install Nginx
        --ssl=* )
            SSL_LIB="${1#*=}"
            case $SSL_LIB in                # Re-define SSL_LIB
                "quictls")                  SSL_LIB="quictls"   ;;
                "boringssl")                SSL_LIB="boringssl" ;;
                "libressl")                 SSL_LIB="libressl"  ;;
                "")
                    echo "ERROR : --ssl= is empty!"
                    exit 1
                    ;;
                *)
                    echo "ERROR : Vaild values for --ssl are -> quictls, boringssl, libressl"
                    exit 1
                    ;;
            esac
            ;;
        *)
            ;;
    esac
    shift
done
```

#### Note :  
* don't forgot to add necessary `lua_package_path` directive to `nginx.conf`, in the http context. else Nginx won't run.
```lua
lua_package_path "/usr/local/lua/?.lua;;";
```

* LibreSSL is broken when compile with Nginx Lua
taken from compiler:
```
error: implicit declaration of function ‘SSL_client_hello_get0_ext’ [-Werror=implicit-function-declaration]
```

# Stop dance for nginx
# =======================
#
# ExecStop sends SIGSTOP (graceful stop) to the 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).
#
