suse12安装mysql8.16

suse12安装mysql8.16

1、查看操作系统类型：

linux-test:~ # cat /proc/version 
Linux version 4.12.14-94.41-default (geeko@buildhost) (gcc version 4.8.5 (SUSE Linux) ) #1 SMP Wed Oct 31 12:25:04 UTC 2018 (3090901)
linux-test:~ # cat /etc/issue

Welcome to SUSE Linux Enterprise Server 12 SP4  (x86_64) - Kernel \r (\l).

2、下载mysql安装包

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

 3、选择对应的操作系统及安装包

4、卸载旧的数据库

参考：

5、创建安装包存放目录

linux-test:~ # mkdir /soft/

6、用ftp工具上传软件到 /soft，上传完成后如下

linux-test:/soft # ls
mysql-8.0.16-2.sles12.x86_64.rpm-bundle.tar

7、解压安装包

linux-test:/soft # tar -xvf mysql-8.0.16-2.sles12.x86_64.rpm-bundle.tar
mysql-community-common-8.0.16-2.sles12.x86_64.rpm
mysql-community-client-8.0.16-2.sles12.x86_64.rpm
mysql-community-devel-8.0.16-2.sles12.x86_64.rpm
mysql-community-server-8.0.16-2.sles12.x86_64.rpm
mysql-community-libs-8.0.16-2.sles12.x86_64.rpm
mysql-community-test-8.0.16-2.sles12.x86_64.rpm

8、依次安装rpm包

rpm -ivh mysql-community-common-8.0.16-2.sles12.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.16-2.sles12.x86_64.rpm
rpm -ivh mysql-community-client-8.0.16-2.sles12.x86_64.rpm
rpm -ivh mysql-community-server-8.0.16-2.sles12.x86_64.rpm

9、修改数据库参数

linux-test:/soft # vi /etc/my.cnf

去掉配置文件中的"default-authentication-plugin=mysql_native_password"的注释符号(#)

并追加参数

#端口
port=6612
#表名不区分大小写，对大小写不敏感
lower_case_table_names=1

10、查下数据库状态（Stopped）

linux-test:/soft # systemctl status mysql.service 或者 systemctl status mysql

● mysql.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysql.service; enabled; vendor preset: disabled)
   Active: inactive (dead) since Thu 2019-05-30 11:39:48 CST; 3h 55min ago
     Docs: man:mysqld(8)
           http://dev.mysql.com/doc/refman/en/using-systemd.html
 Main PID: 1277 (code=exited, status=0/SUCCESS)
   Status: "SERVER_SHUTTING_DOWN"

May 30 11:32:18 linux-test systemd[1]: Starting MySQL Server...
May 30 11:32:26 linux-test systemd[1]: Started MySQL Server.
May 30 11:39:46 linux-test systemd[1]: Stopping MySQL Server...
May 30 11:39:48 linux-test systemd[1]: Stopped MySQL Server.
linux-test:/soft # 

11、启动数据库

linux-test:/soft # systemctl start mysql
或者
linux-test:/soft # systemctl start mysql.service

12、再次查看数据库状态（Started）

linux-test:~ # systemctl status mysql
或者
linux-test:~ # systemctl status mysql.service
● mysql.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysql.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2019-05-30 15:38:08 CST; 43s ago
     Docs: man:mysqld(8)
           http://dev.mysql.com/doc/refman/en/using-systemd.html
  Process: 4072 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS)
 Main PID: 4093 (mysqld)
   Status: "SERVER_OPERATING"
    Tasks: 38 (limit: 512)
   CGroup: /system.slice/mysql.service
           └─4093 /usr/sbin/mysqld

May 30 15:38:07 linux-test systemd[1]: Starting MySQL Server...
May 30 15:38:08 linux-test systemd[1]: Started MySQL Server.

13、查看初始化密码

启动数据库后，MySQL会给我们在/var/log/mysqld.log下，为root用户生成了一个初始化密码

linux-test:~ # grep 'temporary password' /var/log/mysql/mysqld.log 
2019-05-15T15:10:45.423765Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: odd5hp4i?rLj

14、登录数据库

linux-test:~ # mysql -uroot -p
Enter password: 
输入：odd5hp4i?rLj
