我想通过 ansible 在 bash 脚本中使用期望工具。首先，执行我的 shell 脚本。检查$JAVA_HOME变量。我设置$JAVA_HOME但在 Ansible 中，我得到一个错误。

我env的$JAVA_HOME：

[root@portal bin]# env | grep JAVA
JAVA_HOME=/usr/java/jdk1.8.0_161

和我的外壳：

#!/usr/bin/expect -f

set timeout 1    
spawn /opt/install.sh

expect  "\[input\] Are you installing the application at the central data center? \[yes/no default: yes\]? \[yes\]\r"
send    "yes\r"

expect  "\[input\] What is the code of central data center \[default: 01\]? \[01\]\r"
send    "01\r"

expect  "What is ip or hostname of your server \[default: localhost\]? \[localhost\]\r"
send     "portal\r"

我的剧本：

- name: --- run portal expect ---
  shell: |
    cd /opt/
    chmod +x portal
    ./portal

Ansible 中的最终错误：

TASK [ansible-portal : --- run portal expect ---]
****************************************************************************************************
fatal: [portal]: FAILED! => {"changed": true, "cmd": "cd /opt/installer/bin/\n chmod +x portal\n ./portal", "delta": "0:00:00.015509", "end": "2018-07-07 14:01:57.971794",

["spawn /opt/installer/bin/install.sh", "Checking input tasks", "Setting ANT_HOME",
 "Checking Java", "Error: No JAVA_HOME is set"]}

像往常一样运行脚本没有问题。

我有这个 JSON 文件：

{ "key11":1010, "key12":12120, "key13":12103 }

如何jq检查与 a 对应的任何值key[0-9][0-9]是否为零，jq如果有则成功退出，否则不成功？

我有一个来自上一个问题的脚本

#!/bin/bash
json=$(cat <<EOF
{"key11":12120,"key11_":13,"key11_yes":12107,
"key12":13492,"key12_no":9,"key12_yes":13483,
"key13":10200,"key13_no":9,"key13_yes":10191,
"key21":16756,"key21_no":30,"key21_yes":16726,
"key22":17057,"key22_no":34,"key22_yes":17023,
"key23":16798,"key23_no":25,"key23_yes":16773,
"key31":2733,"key31_yes":2733,
"key32":2561,"key32_yes":2561,
"key33":2570,"key33_yes":2570}
EOF
)
json2=$(echo ${json}|jq 'with_entries(if (.key|test("key[0-9][0-9]$")) then ( {key: .key, value: .value } ) else empty end )')

结果是：

{ "key11": 12120, "key12": 13492, "key13": 10200, "key21": 16756, "key22": 17057, "key23": 16798, "key31": 2733, "key32": 2561, "key33": 2570 }

现在我想检查附加到所有键$json2的值，然后如果任何条目的值为零返回0。

我有ips包含内容的文件：

192.168.10.10 3306
192.168.10.20 3306

我的脚本是：

1 #!/bin/bash
  2
  3 p=0
  4 cat /root/ips | while read host port
  5  do
  6    check_up=$(bash -c 'exec 3<> /dev/tcp/'$host'/'$port';echo $?' 2>/dev/null)
  7     if [ $check_up != 0 ]
  8         then
  9           p=$[$p+1]
 10           echo "(1):p in loop = $p"
 11     fi
 12         echo "(2):p in loop = $p"
 13  done
 14      echo "(3):p out loop = $p"
 15
 16     if [ $p % 2 != 0 ]
 17        then
 18             exit 1
 19      fi
~

输出是：

[root@db1 ~]# ./new-script.sh
(1):p in loop = 1
(2):p in loop = 1
(1):p in loop = 2
(2):p in loop = 2
(3):p out loop = 0
./new-script.sh: line 16: [: too many arguments

为什么echo "(3):p out loop = $p"返回0（第一个值$p）！？最后一个值$p是什么时候2？另外，如何修复第 16 行的错误？

实际上，我从事实变量中获得了 ssh 连接。

我在模板中的代码（get-ip.j2）：

nod= {{ ansible_env.SSH_CONNECTION }}

我的输出是：

nod= 192.168.231.115 55414 192.168.231.91 22

现在，我怎样才能从中分离192.168.231.91？

这个错误是什么意思？

[root@db2 zabbix]# zabbix_sender -z zabbix -s zabbix -k mysql[Threads_running] -o 100 -vv

另外这个链接我完全解释了我的配置和问题。

我在这条路径上安装了 zookeeper /opt/zookeeper。

当我想与客户端连接时，出现此错误：

请说明错误的原因。还需要做什么才能在 syslog 中注册 zookeeper 日志？谢谢。
