linux安装mysql5.1_linux rpm方式安装mysql5.1

1、检测系统是否已经安装过mysql或其依赖，若已装过要先将其删除

首先需要先停止mysqld服务，否则直接卸载rpm包后，重新安装的mysql没有初始密码

[root@node2 mysql-5.7.26]# systemctl stop mysqld

[root@node2 mysql-5.7.26]# rpm -qa|grepmysql

mysql-community-libs-5.7.26-1.el7.x86_64

mysql-community-common-5.7.26-1.el7.x86_64

mysql-community-client-5.7.26-1.el7.x86_64

mysql-community-server-5.7.26-1.el7.x86_64

[root@node2 mysql-5.7.26]# rpm -e mysql-community-server-5.7.26-1.el7.x86_64

[root@node2 mysql-5.7.26]# rpm -e mysql-community-client-5.7.26-1.el7.x86_64

[root@node2 mysql-5.7.26]# rpm -e mysql-community-libs-5.7.26-1.el7.x86_64

[root@node2 mysql-5.7.26]# rpm -e mysql-community-common-5.7.26-1.el7.x86_64

卸载顺序为server->client->libs->common

将剩余mysql目录删除干净

[root@node2 mysql-5.7.26]# find / -name mysql/etc/selinux/targeted/active/modules/100/mysql/var/lib/mysql/var/lib/mysql/mysql/usr/share/mysql

[root@node2 mysql-5.7.26]# rm -rf var/lib/mysql

[root@node2 mysql-5.7.26]# rm -rf /usr/share/mysql

[root@node2 mysql-5.7.26]# rm -rf /var/log/mysqld.log

2、下载rpm包

mkdir /usr/local/src/mysql-5.7.26cd/usr/local/src/

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-server-5.7.26-1.el7.x86_64.rpm

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-client-5.7.26-1.el7.x86_64.rpm

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-common-5.7.26-1.el7.x86_64.rpm

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-libs-5.7.26-1.el7.x86_64.rpm

3、安装rpm包

按照依赖顺序依次安装rpm包，依赖关系为common->libs->client->server

rpm -ivh mysql-community-common-5.7.26-1.el7.x86_64.rpm

rpm-ivh mysql-community-libs-5.7.26-1.el7.x86_64.rpm

rpm-ivh mysql-community-client-5.7.26-1.el7.x86_64.rpm

rpm-ivh mysql-community-server-5.7.26-1.el7.x86_64.rpm

在安装mysql-community-common-5.7.26-1.el7.x86_64.rpm ,可能会报错：

file /usr/share/mysql/czech/errmsg.sys from install of mysql-community-common-5.7.26-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.60-1.el7_5.x86_64file /usr/share/mysql/danish/errmsg.sys from install of mysql-community-common-5.7.26-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.60-1.el7_5.x86_64

提示是文件与mariadb-libs-1:5.5.60-1.el7_5.x86_64包里的冲突，卸载mariadb-libs-1:5.5.60-1.el7_5.x86_64即可

rpm -e mariadb-libs-1:5.5.60-1.el7_5.x86_64 --nodeps

4、验证

[root@node2 mysql-5.7.26]# whereismysql

mysql:/usr/bin/mysql /usr/lib64/mysql /usr/share/mysql /usr/share/man/man1/mysql.1.gz

[root@node2 mysql-5.7.26]# whereismy.cnf

my:/etc/my.cnf

编辑my.cnf

[mysqld]

datadir=/home/mysql-5.7.26/datauser=mysql

symbolic-links=0#server_id=71#gtid_mode=on #开启gtid模式

#enforce_gtid_consistency=on #强制gtid一致性

#log-bin=slave-71#开启二进制日志

#binlog_format=row

log-error=/home/mysql-5.7.26/log/mysqld.log

[mysqld_safe]

log-error=/home/mysql-5.7.26/log/mysqld.log

建立相关目录

[root@localhost mysql-5.7.26]# mkdir /home/mysql-5.7.26/[root@localhost mysql-5.7.26]# mkdir /home/mysql-5.7.26/log

[root@localhost mysql-5.7.26]# mkdir /home/mysql-5.7.26/data

[root@localhost mysql-5.7.26]# chown -R mysql:mysql /home/mysql-5.7.26/

5、第一次启动mysql服务

systemctl start mysqld

[root@node2 src]# netstat-tunlp |grep 3306tcp60 0 :::3306 :::* LISTEN 22905/mysqld

查看3306端口，启动成功，查看第一次运行mysql时，系统分配的root账号临时密码，在日志文件里搜索'temporary password'

[root@node3 mysql-5.7.26]# grep 'temporary password' /var/log/mysqld.log2019-05-03T07:30:18.845325Z 1 [Note] A temporary password is generated for root@localhost: _:fwrY:W-8;l

6、利用密码，启动mysql客户端并修改root账号密码

[root@node3 mysql-5.7.26]# mysql -uroot -p

Enter password:

mysql>alter user 'root'@'localhost' identified by 'xxxxxxx';

Query OK,0 rows affected (0.00sec)

mysql> quit

7、利用新密码重新登录mysql

[root@node3 mysql-5.7.26]# mysql -uroot -p

Enter password:

mysql>

8、设置远程连接权限

update user set host = ’%’ where user = ’root’; //出现报错可以忽略

grant all privileges on*.* to root@'%' identified by "mypassword";

flush privileges;

9、查看结果

select host,user,password from user;
