Mysql 二進位安裝方法
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用戶組
groupadd mysql
b. 新增用戶
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.初始化數據和指定安裝目錄和數據目錄
./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql5.7/ --datadir=/usr/local/mysql5.7/data/
6複製啟動文件
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 （最下麵添加）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 root@localhost: 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、 修改用戶密碼
mysql> alter user 'root'@'localhost' identified by 'youpassword';
或者
mysql> set password=password("youpassword");
2、刷新許可權
mysql> flush privileges;
mysql> help contents
