1 . 安裝新版mysql前，需將系統自帶的mariadb-lib解除安裝

[root@slave mytmp]# rpm -qa|grep mariadb
mariadb-libs-5.5.44-2.el7.centos.x86_64
[root@slave mytmp]# rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64

2 . 解壓mysql

[[email protected] mytmp]# tar -zxf mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar
[[email protected]
 
 mytmp]# ls
mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar                 mysql-community-libs-5.7.16-1.el7.x86_64.rpm
mysql-community-client-5.7.16-1.el7.x86_64.rpm           mysql-community-libs-compat-5.7.16-1.el7.x86_64.rpm
mysql-community-common-5.7.16-1.el7.x86_64.rpm           mysql-community-minimal-debuginfo-5.7
 
.16-1.el7.x86_64.rpm
mysql-community-devel-5.7.16-1.el7.x86_64.rpm            mysql-community-server-5.7.16-1.el7.x86_64.rpm
mysql-community-embedded-5.7.16-1.el7.x86_64.rpm         mysql-community-server-minimal-5.7.16-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.16-1.el7.x86_64.rpm  mysql-community-test-5.7
 
.16-1.el7.x86_64.rpm
mysql-community-embedded-devel-5.7.16-1.el7.x86_64.rpm

3 . 使用rpm -ivh命令依次進行安裝

rpm -ivh mysql-community-common-5.7.16-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.16-1.el7.x86_64.rpm 

rpm -ivh mysql-community-client-5.7.16-1.el7.x86_64.rpm

安裝mysql-community-server-5.7.16-1.el7.x86_64.rpm 前需要安裝libaio-0.3.107-10.el6.x86_64.rpm

下載地址：
http://mirror.centos.org/centos/6/os/x86_64/Packages/libaio-0.3.107-10.el6.x86_64.rpm

安裝libaio庫：
rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm（若在有網情況下可執行yum install libaio）

安裝mysql-community-server：
rpm -ivh mysql-community-server-5.7.16-1.el7.x86_64.rpm

4 . 初始化資料庫

// 指定datadir, 執行後會生成~/.mysql_secret密碼檔案
[root@slave mytmp]# mysql_install_db --datadir=/var/lib/m

// 初始化，執行生會在/var/log/mysqld.log生成隨機密碼
[root@slave mytmp]# mysqld --initialize

5 . 更改mysql資料庫目錄的所屬使用者及其所屬組，並啟動mysql資料庫

[root@slave mytmp]# chown mysql:mysql /var/lib/mysql -R
[root@slave mytmp]# systemctl start mysqld.service

6 . 登入到mysql，更改root使用者的密碼

// password 通過 cat ~/.mysql_secret 命令可以檢視初始密碼

[[email protected] mytmp]# mysql -uroot -p
Enter password: 

mysql> set password=password('1234');

7 . 建立使用者，及作許可權分配

mysql> CREATE USER 'zz'@'%' IDENTIFIED BY '1234'; 

mysql> GRANT ALL PRIVILEGES ON *.* TO 'zz'@'%';

mysql> FULSH PRIVILEGES;

8 . 遠端登陸授權

mysql> grant all privileges on *.* to 'root'@'%' identified by '1234' with grant option;

mysql> flush privileges;

9 . 設定mysql開機啟動

// 檢查是否已經是開機啟動
systemctl list-unit-files | grep mysqld

// 開機啟動
systemctl enable mysqld.service
