为什么bash脚本，必须创建并运行zabbix服务器，执行时没有错误，但结果是错误的？

所有人。我ve started to learn bash and DevOps, lost 2 days, but I can不明白以下几点：requirments
4
- mariadb
- Centos 7
- DB mysql
服务器版本
我需要编写bash脚本(问题末尾的脚本)，该脚本创建并运行zabbix服务器(确切地说是4个版本)。当我一步一步地手动运行脚本(手动将每个命令插入pwsh中)时，可以使用两种方法创建db (example1或example2) --它是正确执行的:创建了zabbix，启动了所有服务，zabbix前端运行良好。但是，当我以根用户或本地用户的身份通过命令运行脚本时：
>sh -c /home/zabbix_server脚本通过以下方式完成：
>Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-server.service to /usr/lib/systemd/system/zabbix-server.service.
>Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.
>Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.在脚本期间或脚本末尾没有错误消息，但是当我尝试手动执行命令create (example1或example2)时，这并不重要：
#Create DB (example1)
mysql -uroot <<EOF
create database zabbix character set utf8 collate utf8_bin;
create user 'zabbix'@'localhost' identified by 'zabbix';
grant all privileges on zabbix.* to 'zabbix'@'localhost';
EOF
#Create DB (example2)
mysql -u root -e "CREATE DATABASE zabbix; CREATE USER zabbix@localhost identified by 'zabbix'; GRANT ALL ON zabbix.* to zabbix@localhost WITH GRANT OPTION;"我收到错误信息：..。不能创建db，则存在zabbix基，但是命令的结果是：
>show databases;不会在db列表中显示db zabbix。
脚本
#!/usr/bin/env bash
setenforce 0
#Install the repository configuration package
rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm
yum clean all
#Install Zabbix server, frontend, agent, database
yum install zabbix-server-mysql -y
yum install zabbix-web-mysql -y

yum install mariadb-server -y
#Start DB

create user 'zabbix'@'localhost' identified by 'zabbix';
grant all privileges on zabbix.* to 'zabbix'@'localhost';
EOF
#Create DB (example2)
mysql -u root -e "CREATE DATABASE zabbix; CREATE USER zabbix@localhost identified by 'zabbix'; GRANT ALL ON zabbix.* to zabbix@localhost WITH GRANT OPTION;"
#Import initial schema and data
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql zabbix
#Configure the database for Zabbix server
echo DBPassword=zabbix >> /etc/zabbix/zabbix_server.conf
#Start zabbix server
systemctl start zabbix-server
#Configure frontend
sed -i 's:# php_value date.timezone.*:php_value date.timezone Europe\/Minsk:g' /etc/httpd/conf.d/zabbix.conf;
#Start httpd
systemctl restart zabbix-server zabbix-agent httpd
#Make Zabbix server and agent processes start at system boot
systemctl enable zabbix-server zabbix-agent httpd回答 2

根据您想要实现的目标，这可能是一个很好的建议：
CREATE DATABASE IF NOT EXISTS zabbix;这就是呼叫的幂等性！

问题是，脚本在末尾(0d)包含一个\r (CR)。用下列方法移除：
tr -d '\r' < old_name_script > new_name_script剧本写得很好。如果有用的话，有一个完整的脚本示例，它创建了zabbix服务器：
#!/usr/bin/env bash
#Disable SELinux
enforceStatus=getenforse
if [ "$enforceStatus" != "Permissive" ]; then
setenforce 0
fi
#Install the repository configuration package
rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
yum clean all
#Install Zabbix server, frontend, agent, database, httpd
yum install zabbix-server-mysql -y
yum install zabbix-web-mysql -y
yum install zabbix-agent -y
yum install mariadb mariadb-server -y
yum install httpd -y
#Start and add to autostart DB mariadb
systemctl start mariadb
systemctl enable mariadb.service
#Create DB (example1)
mysql -uroot <<EOF
create database zabbix character set utf8 collate utf8_bin;
create user 'zabbix'@'localhost' identified by 'zabbix';
grant all privileges on zabbix.* to 'zabbix'@'localhost';
EOF
#Import initial schema and data
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql zabbix
#Configure the database for Zabbix server
echo DBPassword=zabbix >> /etc/zabbix/zabbix_server.conf
#Configure frontend
sed -i 's:# php_value date.timezone.*:php_value date.timezone Europe\/Minsk:g' /etc/httpd/conf.d/zabbix.conf;
#Start zabbix server processes start at system boot
systemctl restart zabbix-server
systemctl enable zabbix-server
#Start httpd processes start at system boot
systemctl restart httpd
systemctl enable httpd
#Start zabbix-agent processes start at system boot
systemctl restart zabbix-agent
systemctl enable zabbix-agent
