Linux自动重启was

在Linux中使用WebSphre，想要在操作系统重启后自动重启was进程，我们可以通过创建shell脚本来实现，每个

进程都需要建立一个脚本，然后将它们加入到 /etc/inittab 文件中，实现was的自动重启，编辑inittab文件需

要root用户权限。

在我们使用startManager.sh、startNode.sh和startServer.sh server1命令时，我们可以加上-script选项来创

建重启脚本：

[wasadmin@wasssl bin]# ./startManager.sh -script start_manager.sh
ADMU0116I: 正在文件
           /opt/IBM/WebSphere/AppServer/profiles/dmgr01/logs/dmgr/startServer.log
           中记录工具信息
ADMU0128I: 正在启动具有 dmgr01 概要文件的工具
ADMU3100I: 正在从服务器读取配置：dmgr
ADMU3300I: 已创建服务器的启动脚本：start_manager.sh

我们可以查看一下生成的 start_manager.sh 脚本文件：

[wasadmin@wasssl bin]# cat start_manager.sh

#!/bin/sh
# start_manager.sh

然后我们通过root用户编辑操作系统的 inittab 文件，在最后一行为 shell 脚本添加一个新的条目。

每个 inittab 条目都会在系统初始化时，启动条目中所指定的进程：

[root@wasssl bin]# vi /etc/inittab   添加下面一行

su wasadmin -c was:235:respawn:/opt/IBM/WebSphere/AppServer/bin/start_manager.sh >/dev/console 2>&1

[root@wasssl bin]# init q    立即生效

su：以非root用户启动进程

235：在系统初始化到运行级别 2、3 或 5 时来操作的机器时，执行脚本

respawn：该进程只要终止就立即重新启动

以下是一个可指定的运行级别列表。运行级别通常缺省为 3 或 5。

0 - 中止

1 - 单用户方式

2 - 多用户，没有 NFS（如果未使用网络，那么此级别等效于 3）

3 - 完整多用户方式

4 - 未使用

5 - X11

6 - 重新引导

startNode.sh和startServer.sh server1 创建脚本方法同上。
