Linux安装mysql

Posted 2021-04-08 Python测试开发成长之路

安装包下载

前往mysql官网下载安装包；

https://downloads.mysql.com/archives/community/

将安装包上传服务器并解压

tar -xvf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz 

将解压后的目录重命名并移动

mv mysql-5.7.24-linux-glibc2.12-x86_64 /usr/local/mysql

创建mysql用户组

groupadd mysqluseradd -r -g mysql mysqlmkdir -p /data/mysql chown mysql:mysql -R /data/mysql 

配置my.conf

vim /etc/my.cnf

[mysqld]bind-address=0.0.0.0port=3306user=mysqlbasedir=/usr/local/mysqldatadir=/data/mysqlsocket=/tmp/mysql.socklog-error=/data/mysql/mysql.errpid-file=/data/mysql/mysql.pid#character configcharacter_set_server=utf8mb4symbolic-links=0explicit_defaults_for_timestamp=true

初始化数据库

cd /usr/local/mysql/bin/./mysqld --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql/ --datadir=/data/mysql/ --user=mysql --initialize

mysql初始化时报错bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory的处理

yum -y install numactl

查看密码

cat /data/mysql/mysql.err

启动mysql

先将mysql.server放置到/etc/init.d/mysql中

service mysql startps -ef|grep mysql

修改密码

./mysql -u root -p

启动mysql -u root -p 报错./mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

yum install libncurses*

SET PASSWORD = PASSWORD('123456');ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;FLUSH PRIVILEGES;

如果不希望每次都到bin目录下使用mysql命令则执行以下命令

ln -s /usr/local/mysql/bin/mysql /usr/bin
