一,准备工作。
查看系统版本:
[root@localhost ~]# uname -a Linux localhost.localdomain 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux [root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.4.1708 (Core) [root@localhost ~]#
mysql的rpm包下载地址
https://dev.mysql.com/downloads/mysql/5.7.html#downloads
下载,mysql-5.7.29-1.el7.x86_64.rpm-bundle.tar 大小520.5M
卸载CentOS7.4系统自带的mariadb
[root@localhost ~]# rpm -qa|grep mariadb mariadb-libs-5.5.56-2.el7.x86_64 [root@localhost ~]# rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64 [root@localhost ~]# rpm -qa|grep mariadb [root@localhost ~]#
将mysql-5.7.29-1.el7.x86_64.rpm-bundle.tar 拷贝到/tmp下,并解压
解压
[root@localhost tmp]# tar xvf mysql-5.7.29-1.el7.x86_64.rpm-bundle.tar mysql-community-embedded-devel-5.7.29-1.el7.x86_64.rpm mysql-community-test-5.7.29-1.el7.x86_64.rpm mysql-community-embedded-5.7.29-1.el7.x86_64.rpm mysql-community-embedded-compat-5.7.29-1.el7.x86_64.rpm mysql-community-libs-5.7.29-1.el7.x86_64.rpm mysql-community-client-5.7.29-1.el7.x86_64.rpm mysql-community-server-5.7.29-1.el7.x86_64.rpm mysql-community-devel-5.7.29-1.el7.x86_64.rpm mysql-community-libs-compat-5.7.29-1.el7.x86_64.rpm mysql-community-common-5.7.29-1.el7.x86_64.rpm
依次安装:
mysql-community-common-5.7.29-1.el7.x86_64.rpm、
mysql-community-libs-5.7.29-1.el7.x86_64.rpm、
mysql-community-client-5.7.29-1.el7.x86_64.rpm、
mysql-community-server-5.7.29-1.el7.x86_64.rpm
安装common
[root@localhost tmp]# rpm -ivh mysql-community-common-5.7.29-1.el7.x86_64.rpm warning: mysql-community-common-5.7.29-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql-community-common-5.7.29-1.e################################# [100%] [root@localhost tmp]#
安装libs
[root@localhost tmp]# rpm -ivh mysql-community-libs-5.7.29-1.el7.x86_64.rpm warning: mysql-community-libs-5.7.29-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql-community-libs-5.7.29-1.el7################################# [100%] [root@localhost tmp]#
安装client
[root@localhost tmp]# rpm -ivh mysql-community-client-5.7.29-1.el7.x86_64.rpm warning: mysql-community-client-5.7.29-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql-community-client-5.7.29-1.e################################# [100%] [root@localhost tmp]#
安装server
[root@localhost tmp]# rpm -ivh mysql-community-server-5.7.29-1.el7.x86_64.rpm warning: mysql-community-server-5.7.29-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql-community-server-5.7.29-1.e################################# [100%] [root@localhost tmp]#
这一步如如果报错,缺依赖的问题,需要挂载CentOS7.4的系统iso镜像,安装perl依赖、net-tools依赖
重启系统,来启动mysql服务
[root@localhost tmp]# reboot
查看防火墙端口,开放3306端口
[root@localhost ~]# firewall-cmd --query-port=3306/tcp
no
[root@localhost ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
[root@localhost ~]# firewall-cmd --reload
success
[root@localhost ~]# firewall-cmd --query-port=3306/tcp
yes
[root@localhost ~]#
设置数据库日志过期天数为14天
获取mysql的root用户的初始密码
[root@localhost ~]# grep \'password\' /var/log/mysqld.log 2020-01-14T01:09:01.515663Z 1 [Note] A temporary password is generated for root@localhost: vx*biwua,8/Q [root@localhost ~]#
以获取mysql的root用户的初始密码登录数据库
[root@localhost ~]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \\g. Your MySQL connection id is 5 Server version: 5.7.29
修改root密码
mysql> alter user \'root\'@\'localhost\' identified by \'2020root$PWD\'; Query OK, 0 rows affected (0.01 sec) mysql>
使密码即时生效
mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql>
允许以root身份远程登录mysql
mysql> GRANT ALL PRIVILEGES ON *.* TO \'root\'@\'%\' IDENTIFIED BY \'2020root$PWD\' WITH GRANT OPTION; Query OK, 0 rows affected, 1 warning (0.00 sec) mysql>
修改mysql的字符集为utf8
编辑文件/etc/my.conf,设置字符集为utf8
vi /etc/my.cnf
重起mysql服务
[root@localhost ~]# service mysqld restart Redirecting to /bin/systemctl restart mysqld.service [root@localhost ~]#
测试登陆
