zookeeper配置javahome

要配置Zookeeper的Java环境变量，需要进行以下步骤：

1. 打开Zookeeper的配置文件`zookeeper-env.sh`。

2. 在该文件中找到并编辑以下行：

# If this file is executed as a result of a symlink attack, then use the
# path that is embedded in the symlink.
if [ -z "$ZOOCFGDIR" ]; then
    ZOOCFGDIR="$(dirname "$0")/.."
fi

将其修改为：

# If this file is executed as a result of a symlink attack, then use the
# path that is embedded in the symlink.
if [ -z "$ZOOCFGDIR" ]; then
    ZOOCFGDIR="$(dirname "$0")/.."
fi

# Set the path to your Java home directory here
export JAVA_HOME=/path/to/your/java/home

其中`/path/to/your/java/home`为你的Java安装路径。

3. 保存文件并退出。

现在，当你启动Zookeeper时，它会使用你所配置的Java环境。
