本文主要是介绍Mysql单机部署,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
Mysql安装包下载地址
官网下载url: http://dev.mysql.com/downloads/mysql/
搜狐下载mirror:http://mirrors.sohu.com/mysql/
Mysql单机部署
1.解压安装包
tar zxf mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.7.30-linux-glibc2.12-x86_64 /usr/local/mysql
2.添加 mysql 用户组 和 mysql 用户
groupadd mysql
useradd -g mysql -g mysql -m mysql
id mysql
3.创建Mysql配置文件
vim /etc/my.cnf
[mysqld] port=3306 basedir=/usr/local/mysql datadir=/usr/local/mysql/data socket=/tmp/mysql.sock user=mysql tmpdir=/tmp bind-address = 0.0.0.0 max_connections=200 character-set-server=utf8mb4 collation-server=utf8mb4_general_ci default-storage-engine=INNODB innodb_buffer_pool_size=64MB max_allowed_packet=16M skip-name-resolve [mysqld_safe] log-error=/usr/local/mysql/data/error.log pid-file=/usr/local/mysql/data/mysql.pid [mysql] default-character-set=utf8mb4 [client] socket=/tmp/mysql.sock default-character-set=utf8mb4
4.创建 data 目录
mkdir /usr/local/mysql/data
5.赋予权限
chown -R mysql:mysql /usr/local/mysql
6.Mysql初始化
cd /usr/local/mysql/bin
./mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
初始密码就是结尾的:##F0)#2d<Ok%
7.配置数据库环境变量
vi /etc/profile
export MYSQL_HOME=/usr/local/mysql export PATH=$MYSQL_HOME/bin:$PATH
source /etc/profile
8.设置Mysql开机自启
cd /usr/local/mysql/support-files/
cp mysql.server /etc/init.d/mysql
chmod +x /etc/init.d/mysql
chkconfig --add mysql
9.启动数据库
service mysql start
10.登录数据库
mysql -u root -p
#也可以通过下列命令查看初始密码
grep "temporary password" /var/log/mysqld.log
11.修改初始密码
alter user 'root'@'localhost' identified by 'Cjz123.'
但是默认使用localhost的话是无法进行远程连接的,要想进行远程连接的话,还需要使用以下命令修改
grant all privileges on *.* to root@'%' identified by 'Cjz123.' with grant option;
