mysql 二进制安装方法

下载mysql

1.解压包

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

2.实际生产环境

mv mysql-5.7.24-linux-glibc2.12-x86_64 /usr/local/mysql5.7 

a.新增mysql用户组

 groupadd mysql

b. 新增用户

opt]# useradd -r -g mysql mysql

c.给mysql 目录权限

chown -r mysql:mysql mysql5.7

3. 到初始化环境的目录

 cd /home/usr/local/mysql5.6/
mkdir data
mkdir log
chown -r mysql:mysql mysql5.7

4.初始化数据和指定安装目录和数据目录

./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql5.7/ --datadir=/usr/local/mysql5.7/data/

6复制启动文件

 cp mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld

7.修改启动路径

 vi /etc/init.d/mysqld
basedir= /usr/local/mysql5.7
datadir= /usr/local/mysql5.7/data

8.增加环境变量 (最下面添加)l

 vi /etc/profile
export mysql_home=" /usr/local/mysql5.7"
export path="$path:$mysql_home/bin"

9.刷新配置文件

source /etc/profile

修改配置文件

vi /etc/my.cnf
[client]
port=3306
[mysqld]
basedir=/usr/local/mysql5.7
datadir=/usr/local/mysql5.7/data
#socket=/usr/local/mysql5.7/mysql.sock
socket=/tmp/mysql.sock
user=mysql
#skip-grant-tables
# disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# settings user and group are ignored when systemd is used.
# if you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/systemd
[mysqld_safe]
log-error=/usr/local/mysql5.7/log/mysqld.log
pid-file=/usr/local/mysql5.7/data/mysqld.pid
#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

11.添加开启自启

 chkconfig --add mysqld
 chkconfig mysqld on

12.启动mysqld

 service mysqld start
 netstat -anpt

13.修改密码(密码初始化的时候有个密码)

2018-11-02t02:07:44.574468z 1 [note] a temporary password is generated for root@localhost: lxyb0%fi#9-s (这个就是密码)
mysql> help contents
error 1820 (hy000): you must reset your password using alter user statement before executing this statement.
mysql> help contents
error 1820 (hy000): you must reset your password using alter user statement before executing this statement.
mysql> show databases;
error 1820 (hy000): you must reset your password using alter user statement before executing this statement.

解决办法

1、 修改用户密码

mysql> alter user 'root'@'localhost' identified by 'youpassword';

或者

mysql> set password=password("youpassword");

2、刷新权限

mysql> flush privileges;
mysql> help contents
