Mysql 二進位制安裝方法

下載mysql

https://dev.mysql.com/downloads/mysql/

1.解壓包

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

2.實際生產環境

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

a.新增Mysql使用者組

 groupadd mysql

b. 新增使用者

opt]# useradd -r -g mysql mysql

C.給mysql 目錄許可權

chown -R mysql:mysql mysql5.7

3. 到初始化環境的目錄

  Cd /home/usr/local/mysql5.6/

mkdir data

mkdir log

chown -R mysql:mysql mysql5.7

 4.初始化資料和指定安裝目錄和資料目錄

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

6複製啟動檔案

  cp mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

7.修改啟動路徑

  vi /etc/init.d/mysqld

basedir= /usr/local/mysql5.7

datadir= /usr/local/mysql5.7/data

8.增加環境變數 （最下面新增）l

  vi /etc/profile

export MYSQL_HOME=" /usr/local/mysql5.7"

export PATH="$PATH:$MYSQL_HOME/bin"

9.重新整理配置檔案

source /etc/profile

修改配置檔案

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.新增開啟自啟

  chkconfig --add mysqld

   chkconfig mysqld on

12.啟動mysqld

   service mysqld start

   netstat -anpt

13.修改密碼（密碼初始化的時候有個密碼）

2018-11-02T02:07:44.574468Z 1 [Note] A temporary password is generated for [email protected]: lXyB0%fi#9-S （這個就是密碼）

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.

解決辦法

1、 修改使用者密碼

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

或者       

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

2、重新整理許可權

mysql> flush privileges;

mysql> help contents
