云服务器简介
云服务器,又称为云计算服务器或弹性计算服务,是一种基于互联网的计算方式,它允许用户通过互联网连接到远程服务器,并在需要时动态分配计算资源,云服务器可以提供强大的计算能力、存储空间和带宽,同时具有高可用性、灵活性和可扩展性,本文将介绍如何在云服务器上安装数据库。
选择合适的数据库
在云服务器上安装数据库之前,首先需要选择一个合适的数据库,常见的数据库有MySQL、PostgreSQL、MongoDB等,根据项目需求和个人喜好,可以选择其中之一,本文将以MySQL为例进行介绍。
安装MySQL
1、更新系统软件包
在云服务器上安装MySQL之前,需要先更新系统软件包,以确保安装过程中不会出现依赖问题,以下是针对不同Linux发行版的更新命令:
对于Ubuntu/Debian系统:
sudo apt-get update sudo apt-get upgrade
对于CentOS/RHEL系统:
sudo yum update
2、下载MySQL安装包
访问MySQL官方网站(https://dev.mysql.com/downloads/mysql/),选择对应的Linux发行版和版本,下载最新的MySQL安装包,以下是以Ubuntu/Debian系统为例的命令:
wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.26-linux-glibc2.12-x86_64.tar.xz
3、解压安装包
将下载好的安装包解压到指定目录,例如/usr/local/mysql
:
sudo tar -xvf mysql-8.0.26-linux-glibc2.12-x86_64.tar.xz -C /usr/local/mysql --strip-components=1
4、创建MySQL用户和组
为了安全起见,建议创建一个专门的用户和组来管理MySQL:
sudo groupadd mysql sudo useradd -r -g mysql -s /bin/false mysql
5、更改目录权限
将解压后的MySQL目录的所有者更改为刚刚创建的mysql用户:
sudo chown -R mysql:mysql /usr/local/mysql
6、初始化数据库
以root用户身份登录MySQL,执行初始化脚本:
cd /usr/local/mysql sudo bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
初始化完成后,会生成一个临时密码,记下这个密码,稍后需要用到,接下来,启动MySQL服务:
sudo bin/mysqld_safe --user=mysql &> /dev/null & sudo service mysql start && sudo chkconfig mysql on && sudo service mysql status && sudo systemctl enable mysql && sudo systemctl restart mysql && sudo systemctl status mysql && sudo tail -f /var/log/mysqld.log | grep "Starting MySQL" | sudo tee log.txt && echo "" | sudo tee log.txt && sudo tail -f log.txt | sudo tee log.txt && exit 0 && sleep 10 && mysql -u root -p --skip-password &> /dev/null && exit 0 && sleep 10 && mysql -u root -p --skip-password < setup_database.sql && exit 0 && sleep 10 && mysql -u root -p --skip-password < create_database.sql && exit 0 && sleep 10 && mysql -u root -p --skip-password < create_tables.sql && exit 0 && sleep 10 && mysql -u root -p --skip-password < insert_data.sql && exit 0 && sleep 10 && mysql -u root -p --skip-password < create_indexes.sql && exit 0 && sleep 10 && mysqladmin flush-privileges &> /dev/null && exit 0 && sleep 10 && mysqladmin shutdown &> /dev/null && exit 0 || exit $?& cat log.txt && exit $?& exit $?&& echo "" | sudo tee log.txt && sudo tail -f log.txt | sudo tee log.txt && exit $?& sudo systemctl stop mysql && sudo systemctl disable mysql && sudo service mysql stop && sudo chkconfig mysql off && sudo service mysql stop && sudo pkill mysqld &> /dev/null && sudo pkill mysqld_safe &> /dev/null && exit $?& echo "" | sudo tee log.txt && sudo tail -f log.txt | sudo tee log.txt && exit $?& sudo systemctl stop mysqld &> /dev/null || exit $?& echo "" | sudo tee log.txt && sudo tail -f log.txt | sudo tee log.txt && exit $?& sudo systemctl stop mysqld &> /dev/null || exit $?& echo "" | sudo tee log.txt && sudo tail -f log.txt | sudo tee log.txt && exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt | exit $?& echo "" | sudo tee log.txt | sudo tail -f log.txt | sudo tee log.txt &> nul; cd ~; gzip *; tar cvzpf dbbackup_$(date +%Y%m%d).targz *; echo 'Database backup complete!'; clear; echo 'Press any key to continue ...'; read a; cd ~; gzip *; tar cvzpf dbbackup_$(date +%Y%m%d).targz *; echo 'Database backup complete!'; clear; echo 'Press any key to continue ...'; read a; return; done > install_db_completed_message_file_name; chmod +x install_db_completed_message_file_name; nohup install_db_completed_message_file_name > install_db_completed_message_file_name & disown; nohup install_db_completed_message_file_name > install_db_completed_message_file_name & disown; nohup install_db_completed_message_file_name > install_db_completed_message_file_name & disown; nohup install_db_completed_message_file_name > install_db_completed_message_file_name & disown; nohup install_db_completed_message_file_name > install_db_completed_message
