安装包下载
前往mysql官网下载安装包；
/archives/community/
将安装包上传服务器并解压
tar-xvfmysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
将解压后的目录重命名并移动
mvmysql-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/mysqlchownmysql:mysql-R/data/mysql
配置my.conf
vim /etc/f
[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/f--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
servicemysqlstartps -ef|grep mysql
修改密码
./mysql-uroot-p
启动mysql -uroot -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*
SETPASSWORD=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
