Deepin系统安装mysql5.7
mysql卸载
sudo apt-get --purge remove mysql-server sudo apt-get --purge remove mysql-client sudo apt-get --purge remove mysql-common 最后再通过下面的命令清理残余 sudo apt-get autoremove sudo apt-get autoclean sudo rm /etc/mysql/ -R sudo rm /var/lib/mysql/ -R
第一次安装请卸载自带mysql
Deepin系统源于debian,和ubuntu同为一个linux分支,与centos及redhat不是一个系列,在使用和安装软件方面有很大不同,本文简要记录在Deepin20版本下,安装mysql5.7的过程。
1.在mysql官网下载mysql-server_5.7.34-1debian10_amd64.deb-bundle.tar安装包(当然要根据自己的debian版本选择合适的版本)。
2.拷贝到合适位置(一般:/usr/local),然后解压:
sudo tar -xf mysql-server_5.7.34-1debian10_amd64.deb-bundle.tar
3.安装mysql
sudo dpkg -i mysql-{common,community-client,client,community-server,server}_*.deb
此时会报错:未安装软件包 libmecab2。
4.更新软件源,在/etc/apt/sources.list文件中添加新的软件源:
deb [by-hash=force] https://mirrors.aliyun.com/deepin/ apricot main contrib non-free
千万记得更新系统软件源缓存,使之生效。
sudo apt-get update
5.安装mysql所需的libmecab2
sudo apt-get -y install libmecab2 libjson-perl
然后输入2次密码即可。
安装后,记得使用命令允许root远程访问:
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '****' WITH GRANT OPTION;
###分开
FLUSH PRIVILEGES;
备注:如果不能使用右键粘贴,则运行命令:set mouse-=a,即可。
接下来修改mysql中字符编码问题:
直接添加mysql的配置文件中编码为utf-8即可:
sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf
在mysqld节点,添加以下:
character-set-server = utf8
重启mysql服务:
sudo systemctl restart mysql.service
查看当前字符编码:
show variables like 'char%'; 得到以下结果: +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+
修改成功。
至此,mysql 5.7的所有安装配置在deepin中已经完成。
/etc/mysql/mysql.conf.d/mysqld.cnf
[mysqld] pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock datadir = /var/lib/mysql log-error = /var/log/mysql/error.log # By default we only accept connections from localhost bind-address = 0.0.0.0 # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 #skip-grant-tables character-set-server = utf8 lower_case_table_names=1
