OpenShift4 节点TimeZone修改

# TimeZone修改

## 1. 新建一个修改TimeZone的脚本

**cat change_timezone_to_shanghai.sh**

```

#!/bin/sh

set -eux

MD5_DST=$(md5sum /usr/share/zoneinfo/Asia/Shanghai | awk '{print $1}')

MD5_SRC=$(md5sum /etc/localtime | awk '{print $1}')

if [[ "${MD5_DST}" != "${MD5_SRC}" ]]; then

rm -rf /etc/localtime

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

fi

```

## 2.将该脚本编码为base64格式

**cat change_timezone_to_shanghai.sh | base64 -w0**

## 3.在`10-worker.yaml`中添加timezone-99bill.service服务和/usr/local/sbin/timezone.sh文件

**cat 10-worker.yaml**

          [Service]
          Type=oneshot
          RemainAfterExit=yes
          User=root

          # SystemD prevents direct execution of the script in /usr/local/sbin,
          # so it is sourced. See the script for functionality.
          ExecStart=/usr/local/sbin/timezone.sh

          # Wait up to 5min for the node to get a real hostname.
          TimeoutSec=300

          [Install]
          WantedBy=multi-user.target
        enabled: true
        name: timezone.service

## 4. 部署该MC

```

oc apply -f 10-worker.yaml

```

这样，worker节点的时区就会改成Shanghai，如果要修改master节点的时区，可以按照上述方法新增master节点的相关mc对象即可。
