一，判断程序的部署环境是nginx还是windows
/** * 判断操作系统是不是windows * * @return true：是win false：是Linux */ public static boolean judgeOs() { String os = System.getProperty("os.name").toLowerCase(); if (os != null && os.startsWith("windows")) { return true; } else { return false; } }
二，开启nginx
（1）开启windows系统的ngin
/** * 开启windows系统的nginx * @throws IOException */ private static void startWinProc() throws IOException{ String myExe = "cmd /c start nginx"; String CONFPREFIXURL = System.getProperty("user.dir") + File.separator + "nginx" + File.separator + "windows"; File dir = new File(CONFPREFIXURL); String[] str = new String[] {}; // 执行命令 Runtime.getRuntime().exec(myExe, str, dir); }
（2）开启linux系统的nginx
/** * 开启linux的nginx * @throws IOException */ private static void startLinuxProc() throws IOException { System.out.println("开启进程:" + "nginx"); String command1 = "/usr/local/nginx/sbin/nginx"; String pro = executeCmd2(command1); System.out.println(pro); }
（3）跨平台开启Nginx
/** * 跨平台启动nginx * * @throws IOException */ private static void startProc() throws IOException { if (judgeOs()) { startWinProc(); } else { startLinuxProc(); } }
三，关闭nginx
（1）关闭windows系统的nginx
/** *关闭windows系统的nginx * @throws IOException */ public static void KillWin() throws IOException{ executeCmd("taskkill /F /IM " + "nginx.exe"); }
（2）关闭linux系统的nginx
/** * 关闭linux系统的nginx * @throws IOException */ private static void killLinuxProc() throws IOException { String command = "pkill -9 nginx"; executeCmd(command); }
（3）nginx的跨平台关闭
/** * 跨平台关闭nginx * @throws IOException */ public static void killProc() throws IOException { if(judgeOs()){ KillWin(); }else{ killLinuxProc(); } }
四，获取项目所在的磁盘位置
String CONFPREFIXURL = System.getProperty("user.dir"); System.out.println(CONFPREFIXURL);
五，获取项目所在主机ip
/** * 获取项目部署环境的ip * @return */ public static String getIP() { String url = "";; try { for (Enumeration e = NetworkInterface.getNetworkInterfaces(); e.hasMoreElements(); ) { NetworkInterface item = e.nextElement(); for (InterfaceAddress address : item.getInterfaceAddresses()) { if (item.isLoopback() || !item.isUp()) { continue; } if (address.getAddress() instanceof Inet4Address) { Inet4Address inet4Address = (Inet4Address) address.getAddress(); url =inet4Address.getHostAddress(); } } } //url = InetAddress.getLocalHost().getHostAddress(); } catch (SocketException e) { throw new RuntimeException(e); } return url; } 更多获取系统变量的方法：
