SUSE12SP3-Mysql5.7安装

一、将如下安装包复制到服务器

mysql-community-client-5.7.24-1.sles12.x86_64.rpm

mysql-community-server-5.7.24-1.sles12.x86_64.rpm

mysql-community-libs-5.7.24-1.sles12.x86_64.rpm

mysql-community-common-5.7.24-1.sles12.x86_64.rpm

二、安装软件 安装顺序安装

sudo rpm -ivh mysql-community-common-5.7.24-1.sles12.x86_64.rpm
sudo rpm -ivh mysql-community-libs-5.7.24-1.sles12.x86_64.rpm
sudo rpm -ivh mysql-community-client-5.7.24-1.sles12.x86_64.rpm 
sudo rpm -ivh mysql-community-server-5.7.24-1.sles12.x86_64.rpm

若是想查询rpm包详细的安装文件列表及每一个文件的实际存储路径，可经过命令rpm -ql来查询，如：

rpm -ql mysql-community-client-5.7.24-1.sles12

/usr/bin/mysql_config_editor
/usr/bin/mysqladmin
/usr/bin/mysqlbinlog

三、修改配置文件/etc/my.cnf

sudo vi /etc/my.cnf

内容以下（可根据实际修改）：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
 
[client]
#password = allspark

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!
# 
#skip-networking
  
# Replication Master Server (default)
# binary logging is required for replication
log-bin = /data/mysql/mysql-bin
  
# binary logging format - mixed recommended
binlog_format = mixed
  
# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id = 1
  
# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended
#log-bin=mysql-bin
  
# Uncomment the following if you are using InnoDB tables

四、初始化

注：5.7版本的rpm包安装以后默认再也不建立数据库，mysql服务也不会自动启动。可是它仍是自动增长了系统用户mysql。

sudo mkdir -p /data/mysql/{data,tmp}       #建立存放数据文件目录，data与tmp之间不能为空格
sudo chown -R mysql /data/mysql      
sudo mysqld --initialize --datadir=/data/mysql/data/ --user=mysql #初始化

初始化成功以后，会将root的默认密码写入文件：/data/mysql/mysql.err 中，以下：

A temporary password is generated for root@localhost: _tVUgaq%P25Q   #这就是root的默认密码

五、启动mysql服务便可

sudo service mysql start

检查MySQL服务是否已经启动：

netstat -nat | grep 3306

六、安装后配置之root密码修改

root初始密码自动生成，默认存放在/data/mysql/mysql.err 中。修改root密码的方式有如下两种，随便哪一个都行
若是没有

vi /etc/my.cnf
2.在[mysqld]中添加
skip-grant-tables
例如：
[mysqld]
这句话加上表示不使用密码进入mysql
skip-grant-tables
datadir=/xxx/xxx/xxx
socket=/xxx/xxx/xxx/mysql.sock

一、命令方式

mysqladmin -u root -p  password 'root' 
Enter password:

二、修改库表数据方式

先登录mysql服务器

mysql -uroot -p # 进入mysql
Enter password:

通常mysql版本

mysql>  set password=password('root'); # 这里是将密码设置为root123 ,请根据实际修改

mysql5.7版本

mysql>  update user set authentication_string = password('root'), password_expired = 'N', password_last_changed = now() where user = 'root';

可是在5.7版本中不存在password字段，全部咱们要用如下修改进行重置密码
update user set authentication_string=password('123456') where user='root';
若是是5.7如下的版本修改密码是这样的
update user set password=password('123456') where user='root';

七、设置远程访问

先登录mysql服务器，受权root用户能够远程登录

mysql -uroot -p # 进入mysql
grant all PRIVILEGES on *.* to root@'%' identified by 'root'; # 这里的root是你的密码
Query OK, 0 rows affected (0.00 sec)# 显示这一句就是对的
flush privileges;
Query OK, 0 rows affected (0.00 sec)# 显示这一句就是对的

若是报错You must reset your password using ALTER USER statement before executing this statement.
则再次设置密码便可
SET PASSWORD = PASSWORD('root');
grant all PRIVILEGES on *.* to root@'%' identified by 'root';
flush privileges;
``
这样就能够链接了，使用工具链接ip:3306

## 八、额外命令

​```bash
CREATE USER 'mysql'@'%' IDENTIFIED BY 'mysql' # 建立mysql用户
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'mysql'@'%'; # 给mysql用户全部权限
FLUSH PRIVILEGES;

八、给MySQL用户全部权限

GRANT Alter, Alter Routine, Create, Create Routine, Create Temporary Tables, Create User, Create View, Delete, Drop, Event, Execute, File, Grant Option, Index, Insert, Lock Tables, Process, References, Reload, Replication Client, Replication Slave, Select, Show Databases, Show View, Shutdown, Super, Trigger, Update ON *.* TO `mysql`@`%`;

经常使用命令

sudo service mysql stop # 中止
sudo service mysql start # 启动
sudo service mysql restart #重启
sudo service mysql status # 查看状态
