麒麟V10安装MySQL
麒麟V10安装MySQL
1、下载MySQL并上传到服务器上
MySQL下载地址
2、查看系统是否已安装Mariadb和MySQL，如果已存在那就卸载
# 查系统是否已经安装mariadb和mysql
[root@localhost mysql]# rpm -qa | grep mariadb
[root@localhost mysql]# rpm -qa | grep mysql

3、解压MySQL安装包并安装MySQL
# 进入存放mysql安装包的目录
[root@localhost mysql]# cd /usr/mysql8
# 解压MySQL压缩包
[root@localhost mysql8]# tar -xvf mysql-8.0.28-1.el8.x86_64.rpm-bundle.tar

4、编辑MySQL配置文件
在配置文件中加上lower_case_table_names=1，这句的意义是不让MySQL区分大小写
[root@localhost etc]# vi /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/8.0/en/server-configuration-defaults.html
[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove the leading "# " to disable binary logging
# Binary logging captures changes between backups and is enabled by
# default. It's default setting is log_bin=binlog
# disable_log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
#
# Remove leading # to revert to previous value for default_authentication_plugin,
# this will increase compatibility with older clients. For background, see:
# https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_default_authentication_plugin
# default-authentication-plugin=mysql_native_password
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
lower_case_table_names=1
5、启动MySQL服务
首先启动MySQL服务，然后修改MySQL的密码，并配置MySQL可远程访问
[root@localhost mysql8]# systemctl start mysqld
[root@localhost mysql8]# cat /var/log/mysqld.log | grep password
2023-06-13T05:55:58.156403Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: Ax1#JAS_Q*LO
2023-06-13T07:08:22.500552Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: *oNXTNGhq7*P
[root@localhost mysql8]# mysql -u root -p
Enter password:
