Question

如何在名为init.sh的shell脚本下运行？我正在运行像这样的./init.sh test123这样的脚本，它给了我消息MONGODB_PASSWORD not defined。作为shell脚本的新手，我不知道这是什么意思？

-z   ==>
Checks if the given string operand size is zero; if it is zero length, then it returns true.

实际文件详细信息：

#!/bin/bash
if test -z "$MONGODB_PASSWORD"; then
    echo "MONGODB_PASSWORD not defined"
    exit 1
fi

auth="-u user -p $MONGODB_PASSWORD"

# MONGODB USER CREATION
(
echo "setup mongodb auth"
create_user="if (!db.getUser('user')) { db.createUser({ user: 'user', pwd: '$MONGODB_PASSWORD', roles: [ {role:'readWrite', db:'piggymetrics'} ]}) }"
until mongo piggymetrics --eval "$create_user" || mongo piggymetrics $auth --eval "$create_user"; do sleep 5; done
killall mongod
sleep 1
killall -9 mongod
) &

# INIT DUMP EXECUTION
(
if test -n "$INIT_DUMP"; then
    echo "execute dump file"
    until mongo piggymetrics $auth $INIT_DUMP; do sleep 5; done
fi
) &

echo "start mongodb without auth"
chown -R mongodb /data/db
gosu mongodb mongod "$@"

echo "restarting with auth on"
sleep 5
exec gosu mongodb /usr/local/bin/docker-entrypoint.sh --auth "$@"

EDIT-1： cat .bash_profile

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
export JAVA_HOME=/opt/jdk1.8.0_181
export M2_HOME=/usr/local/apache-maven-3.5.4
export MAVEN_OPTS=-Xms256m -Xmx512m
export M2=$M2_HOME/bin


# THIS IS SETTING TO RUN THE PiggyMetrix
export CONFIG_SERVICE_PASSWORD=test123
export NOTIFICATION_SERVICE_PASSWORD=test123
export STATISTICS_SERVICE_PASSWORD=test123
export ACCOUNT_SERVICE_PASSWORD=test123
export MONGODB_PASSWORD=test123

export PATH=$M2:$PATH:/opt/jdk1.8.0_181/bin/:$HOME/.local/bin:$HOME/bin

使用

test -z "$MONGODB_PASSWORD"

您正在测试变量$MONGODB_PASSWORD是否不为空。

在运行脚本之前，您必须将密码存储在变量中：

MONGODB_PASSWORD="password" ./init.sh

如何使用-z参数运行shellscript？
