Automated Nginx Installation and Configuration Script for CentOS/Ubuntu

Nginx (engine x) is a high‑performance HTTP and reverse‑proxy web server widely used in production environments. The following Bash script performs a completely automated download, verification, compilation, installation, and systemd service configuration of Nginx, supporting both CentOS‑based and Ubuntu‑based distributions.

The script defines helper functions to check command exit status, download the source tarball, install required dependencies, configure, compile, and install Nginx, and finally create and enable a systemd service unit.

    echo "编辑systemd服务管理脚本"
    cat > /tmp/nginx.service <

Save the script as nginx_install.sh and run it with:

chmod +x nginx_install.sh && ./nginx_install.sh

After the script finishes, you can access the server’s IP address to verify that Nginx is serving pages. Common Nginx management commands are provided below:

# 启动nginx
systemctl start nginx
# 停止nginx
systemctl stop nginx
# 设置开机启动
systemctl enable nginx
# 取消开机启动
systemctl disable nginx

For a one‑click installation, you can also execute the following command, which fetches and runs the script directly:

bash -c "$(curl -L s.aaa.al/nginx_install.sh)"
