騰訊雲伺服器Ubuntu 16.04.1 LTS zookeeper-3.4.11安裝啟動失敗
zookeeper安裝後啟動報許可權不足：
[email protected]:/opt/zookeeper-3.4.8/bin$ ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfg
Starting zookeeper ... ./zkServer.sh: line 149: /tmp/zookeeper/zookeeper_server.pid: Permission denied
FAILED TO WRITE PID
我們用sudo 啟動：
[email protected]:/opt/zookeeper-3.4.8/bin$ sudo ./zkServer.sh start
[sudo] password for kevin:
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED我們看到啟動並不報錯，但是zookeeper 並沒有啟動成功，我們看一下zookeeper服務狀態：
[email protected]:/opt/zookeeper-3.4.8/bin$ sudo ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfg
Error contacting service. It is probably not running. 看了一下zookeeper的啟動日誌zookeeper.out （在bin目錄下）：
nohup: failed to run command ‘java’: No such file or directory 然後自己又在命行裡執行了一下java javac 沒有任何問題，但是當我執行sudo java ,sudo javac 的時候就提提示錯誤sudo: java: command not found
查了一些資料後得知：
sudo是預設是去找系統預設的jdk，而系統預設的jdk路徑是/usr/bin/下面使用sudo update-alternatives --list java檢視下：
[email protected]:/opt/zookeeper-3.4.8/bin$ sudo update-alternatives --list java
update-alternatives: error: no alternatives for java這裡我們並沒有看到 java 的軟連結，可能大多數人linux下安裝jkd 的方式通常是下載一個jdk的安裝包，解壓到指定目錄下，然後配置一下環境變數在/etc/profile或者.bashrc （這裡不再贅餘jdk安裝）
執行如下：
[email protected]:/opt/zookeeper-3.4.8/bin$
[sudo] password for kevin: sudo update-alternatives --install /usr/bin/java java /opt/java/jdk1.8.0_77/bin/java 300
update-alternatives: using /opt/java/jdk1.8.0_77 to provide /usr/bin/java (java) in auto mode再來看一下（已經有了）：
[email protected]:/opt/zookeeper-3.4.8/bin$ update-alternatives --list java
/opt/java/jdk1.8.0_77此時我們再來sudo 啟動一下zookeeper:
[email protected]:/opt/zookeeper-3.4.8/bin$ sudo ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED再檢查一下是否啟動：
[email protected]:/opt/zookeeper-3.4.8/bin$ sudo ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.8/bin/../conf/zoo.cfg
Mode: standalone再看一下程序：
[email protected]:/opt/zookeeper-3.4.8/bin$ netstat -an|grep 2181
tcp6 0 0 :::2181 :::* LISTEN 搞定！！
