Linux安裝64位Mysql5.7.22
以安裝在/usr/local目錄下為例
1.下載安裝包地址:https://dev.mysql.com/downloads/file/?id=476936,安裝包保存到/usr/local
2.解壓:
cd /usr/local
tar -zxvf mysql-5.7.22-linux-glibc2.12-x86_64.tar
mv mysql-5.7.22-linux-glibc2.12-x86_64 mysql-5.7.22
3.添加用戶組和用戶
#添加用戶組
groupadd mysql
#添加用戶mysql 到用戶組mysql
useradd -g mysql mysql
4.安裝
cd /usr/local/mysql-5.7.22
mkdir data
chown -R mysql:mysql ./
./bin/mysqld –-initialize --user=mysql --basedir=/usr/local/mysql-5.7.22/ --datadir=/usr/local/mysql-5.7.22/data/
#將mysql/目錄下除了data/目錄的所有文件,改回root用戶所有
chown -R root .
#mysql用戶只需作為mysql-5.7.20/data/目錄下所有文件的所有者
chown -R mysql data
5.復制啟動文件
cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
cp /bin/my_print_defaults /usr/bin/
6.修改啟動腳本
vi /etc/init.d/mysqld
#修改項:
basedir=/usr/local/mysql-5.7.20/
datadir=/usr/local/mysql-5.7.20/data
port=3306
#加入環境變量,編輯 /etc/profile,這樣可以在任何地方用mysql命令了
vi /etc/profile
#添加mysql路徑,加入下面內容,按ESC-->:wq保存
export PATH=$PATH:/usr/local/mysql-5.7.20/bin
#刷新立即生效
source /etc/profile
7.修改mysql配置項
vi /etc/my.cnf
配置如下:
[mysqld]
basedir = /usr/local/mysql-5.7.22
datadir = /usr/local/mysql-5.7.22/data
socket = /tmp/mysql.sock
user = mysql
tmpdir = /tmp
symbolic-links=0
[mysqld_safe]
log-error = /usr/local/mysql-5.7.22/data/error.log
pid-file = /usr/local/mysql-5.7.22/data/mysql.pid
!includedir /etc/my.cnf.d
8.啟動mysql
service mysqld start
如啟動失敗,刪除 /usr/local/mysql-5.7.22/data下所有文件,重新執行./bin/mysqld –-initialize --user=mysql --basedir=/usr/local/mysql-5.7.22/ --datadir=/usr/local/mysql-5.7.22/data/,再啟動
9.進入mysql修改初始密碼,修改遠程連接的用戶權限問題
mysql -uroot -p
ALTER USER USER() IDENTIFIED BY ‘123‘;
use mysql;
update user set host = ‘%‘ where user =‘root‘;
flush privileges;
