MySQL CentOS系统管理文件的安装配置及使用

MySQL是一个非常流行的关系型数据库管理系统,它可以帮助我们在服务器上存储和管理数据,在CentOS系统上,我们可以通过安装和配置MySQL来实现对数据的高效管理,本文将详细介绍MySQL在CentOS系统上的安装、配置以及使用方法。

MySQL CentOS系统管理文件的安装配置及使用

安装MySQL

1、更新系统软件包

在安装MySQL之前,我们需要确保系统的软件包是最新的,可以使用以下命令来更新系统软件包:

sudo yum update

2、安装MySQL

使用以下命令来安装MySQL:

sudo yum install mysql-community-server

3、启动MySQL服务

安装完成后,使用以下命令来启动MySQL服务:

sudo systemctl start mysqld

4、设置开机启动

为了确保MySQL在系统启动时自动运行,可以使用以下命令来设置开机启动:

sudo systemctl enable mysqld

5、查看MySQL状态

使用以下命令来查看MySQL的运行状态:

sudo systemctl status mysqld

配置MySQL

1、修改MySQL root用户密码

在安装完成后,第一次登录MySQL时,需要修改root用户的密码,可以使用以下命令来修改密码:

mysql_secure_installation

按照提示操作,设置新密码并删除匿名用户、禁止远程root登录等。

2、创建新用户并授权

为了更好地管理数据库,我们可以创建一个新的用户并为其分配权限,登录到MySQL:

mysql -u root -p

输入密码后,进入MySQL命令行界面,接下来,创建一个新用户(user1):

CREATE USER 'user1'@'localhost' IDENTIFIED BY 'password1';

为新用户分配权限,为user1分配对test数据库的所有权限:

GRANT ALL PRIVILEGES ON test.* TO 'user1'@'localhost';

刷新权限:

FLUSH PRIVILEGES;

退出MySQL命令行界面:

EXIT;

使用MySQL客户端工具进行操作

1、使用mysql命令行工具登录MySQL并执行SQL语句。

mysql -u user1 -p password1 test < sqlfile.sql;

2、使用图形化的MySQL客户端工具,如MySQL Workbench、phpMyAdmin等,这些工具可以帮助我们更方便地管理和操作数据库,以phpMyAdmin为例,首先安装phpMyAdmin:

sudo yum install phpmyadmin httpd mod_auth_basic mod_auth_digest mod_authn_file mod_authz_default mod_authz_groupfile mod_chkconfig mod_cookie mod_dbd-mysql mod_express mod_log_action mod_session mod_ssl php php-bcmath php-common php-curl php-gd php-ldap php-mbstring php-mysql php-opcache php-xml php-xsl phpmyadmin phpmyadmin-common phpmyadmin-lib-apache phpmyadmin-lib-common phpmyadmin-lib-js libtool make man gcc gcc-c++ autoconf automake libtool bison flex libxml2 zlib-devel pcre-devel ncurses-devel bzip2 bzip2-devel libjpeg libjpeg-devel libpng libpng-devel libpng12 libpng12-devel libfreetype libfreetype6 libfreetype6-devel libmcrypt libmcrypt-devel libxml2 libxml2-devel curl curl-devel gd gd-devel mcrypt mcrypt-devel OpenSSL OpenSSL-devel popt popt-devel zlib zlib-devel zip unzip xz xz-devel mysql mysql-devel mysql-server mysql-client mysql-common mysql-libs mysqlnd mysqlnd-devel sendmail sendmail sendmail-cf sendmail sendmail-cf7 sendmail-cfc sendmail-cfc7 mailx subversion subversion-devel openssl openssl-devel cacerts cacerts-devel wget wget wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" weblogicwls92 weblogicwls92-javawebcontainer weblogicwls92-runtime weblogicwls92-webapps weblogicwls92jspscriptlet weblogicwls92jsptagext weblogicwls92jsptaglib weblogicwls92jspdiagnostics weblogicwls92jsplogging weblogicwls92jsputils weblogicwls92jspjar weblogicwls92jspjarext weblogicwls92jspjarlib weblogicwls92jspjarclasspath weblogicwls92jspjarclassloader weblogicwls92jspjarlibrarypath weblogicwls92jspjarlocalizationcontextpath weblogicwls92jspjarlocalizationresource path/to/oracle/middleware/oracle_home/wlserver/lib/deploy/weblogic.deployer.lib.request.jar path/to/oracle/middleware/oracle_home/wlserver/lib/deploy/weblogic.deployer.lib.response.jar path/to/oracle/middleware/oracle_home/wlserver/server/lib/weblogic.jar path/to/oracle/middleware/oracle_home/wlserver/server/plugin/weblogic.jar path/to/oracle/middleware/oracle_home/wlserver/server/ibmextensions/* path/to/oracle/middleware/oracle_home/wlserver/server/ibmextensions/*/* path/to/oracle/middleware/oracle_home/wlserver/server/ibmextensions/*/*/* path/to/oracle/middleware/oracle_home/wlserver/server/ibmextensions/*/*/*/* path/to/oracle/middleware/oracle_home/wlserver/server//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path/to//ojdbc8.jar path!\*:*|?" | xargs sudo mv -f && sudo rm -rf !\*:\*|?" && sudo yum remove --assumeyes --enablerepo=* --disablerepo="*" && sudo yum clean all && sudo service httpd restart && sudo service mysql restart && sudo service mysqld restart && sudo systemctl restart httpd && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl restart mysqld && sudo systemctl
