从脚本中启动另一个脚本

Question

所以我有这个#!/bin/bash安装一些东西的脚本，然后在脚本的末尾我希望它运行下一个脚本。

例如，脚本 1 安装了 LAMP，但在该脚本的末尾，我希望它运行一个不同的#!/bin/bash脚本（例如，运行 moodle）。

我尝试将 sudo ./Mysql#2（我的下一个脚本）放在最后，但当脚本运行时到达该部分时，我意外地收到“错误重定向”提示。仅供参考，MYSQL#2 位于同一目录中。我尝试链接的所有脚本都位于同一目录中。

第一个脚本：

#!/bin/bash 

DATE=$(date)

export DEBIAN_FRONTEND='noninteractive'

# Install apache and begin ssl setup 
apt-get -y install apache2
a2enmod ssl
service apache2 restart
mkdir /etc/apache2/ssl

echo '-------------------------------------------'
echo 'installed apache and created ssl directory.' 
echo '-------------------------------------------'

sleep 3 

echo ""
echo ""

echo ------------------------------------------------------------------------------------#
echo 'Now Generate SSL Key. Now we will use sed to adjust the values in default-ssl.conf.' 
echo ------------------------------------------------------------------------------------#

sleep 5 

#You can generate an openssl key non-interactively if you uncomment the line below. 
#My server already has run this command, so the key gen breaks, but if you running this command to grade it should work.
openssl genrsa -out /etc/apache2/ssl/apache.key 2048
openssl req -nodes -new -key /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.csr -subj "/C=US/ST=Texas/L=Abilene/O=ACU/OU=IT410/CN=69.28.90.132"



echo -----------------#
echo 'Changed values.' 
echo -----------------#

sleep 2 

echo ""
echo ""

a2ensite default-ssl.conf
service apache2 restart

echo ""
echo ""

echo --------------------------------------# 
echo 'Time to grab php7.0 and php7.0 mods.'
echo --------------------------------------#

sleep 3 


# install php mods + configure mailutils for only outgoing mail 
export DEBIAN_FRONTEND='noninteractive'
apt-get install -y php7.0 php7.0-mysql libapache2-mod-php7.0 php7.0-curl php-pear php-db php7.0-ldap mailutils  

echo "" 
echo "" 

echo '-----------------------------------'
echo 'installed php, php mods, and mail.' 
echo '-----------------------------------'

sleep 3 

echo ""
echo ""

echo --------------------------------------#
echo 'Setting inet_interfaces to localhost.'
echo --------------------------------------#

sleep 3 

sed -i 's@inet_interfaces.*@inet_interfaces = localhost@' /etc/postfix/main.cf

echo ""
echo ""

echo ------------------------#
echo 'Made mail outgoing only.'  
echo ------------------------#

service postfix restart

sudo ./Mysql#2  

第二个脚本：

#!/bin/bash

#make sure you run script as sudo mysql-install.sh (That way, all commands within the script will be run with root privileges and you only need to give the password once 
#when launching the script. If you need a particular command within the script to be run without sudo privileges, you can run it as a regular user with: sudo -u username command

我该如何解决这个问题？我不希望每个脚本运行时出现任何中断，我希望按顺序运行它们而无需触摸键盘。

Answer 1

如果所有脚本都在当前目录中并且具有执行权限，则可以直接从另一个 shell 脚本调用一个 shell 脚本。

请参阅以下示例。

脚本master：

#!/bin/bash

echo "*** start master ***

assumption:  all scripts are in the current directory
             and they have execute permissions.

alternative: create the directory 'bin' in your home directory and move
             your scripts to there. Then (in any new terminal window)
             your scripts will be in PATH and can be called without any
             explicit path"

./sub1
./sub2

sudo ./sub1   # run with sudo should work too

echo "*** finish master ***"

脚本sub1：

#!/bin/bash

echo "*** start sub1 ***"

whoami

echo "*** finish sub1 ***"

脚本sub2：

#!/bin/bash

echo "*** sub2 ***"

以用户“sudodus”身份运行时的命令和输出

$ ./master
*** start master ***

assumption:  all scripts are in the current directory
             and they have execute permissions.

alternative: create the directory 'bin' in your home directory and move
             your scripts to there. Then (in any new terminal window)
             your scripts will be in PATH and can be called without any
             explicit path
*** start sub1 ***
sudodus
*** finish sub1 ***
*** sub2 ***
[sudo] password for sudodus: 
*** start sub1 ***
root
*** finish sub1 ***
*** finish master ***

Answer 2

而不是像这样从第一个脚本运行第二个脚本：

sudo ./Mysql#2

尝试这样做：

sudo -s source ./Mysql#2

或者如果你以 root 身份运行脚本，则只需像这样运行第二个脚本：

source ./Mysql#2
