SUSE12SP3-Mysql5.7安裝

一、將如下安裝包複製到服務器

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、安裝軟件 安裝順序安裝

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

若是想查詢rpm包詳細的安裝文件列表及每一個文件的實際存儲路徑，可經過命令rpm -ql來查詢，如：

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

/usr/bin/mysql
/usr/bin/mysql_config_editor
/usr/bin/mysqladmin
/usr/bin/mysqlbinlog
/usr/bin/mysqlcheck
/usr/bin/mysqldump

三、修改配置文件/etc/my.cnf

sudo vi /etc/my.cnf

內容以下（可根據實際修改）：

# 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包安裝以後默認再也不建立數據庫，mysql服務也不會自動啓動。可是它仍是自動增長了系統用戶mysql。

sudo mkdir -p /data/mysql/{data,tmp}       #建立存放數據文件目錄，data與tmp之間不能爲空格
sudo chown -R mysql /data/mysql      
sudo mysqld --initialize --datadir=/data/mysql/data/ --user=mysql #初始化

初始化成功以後，會將root的默認密碼寫入文件：/data/mysql/mysql.err 中，以下：

A temporary password is generated for root@localhost: _tVUgaq%P25Q   #這就是root的默認密碼

五、啓動mysql服務便可

sudo service mysql start

檢查MySQL服務是否已經啓動：

netstat -nat | grep 3306

六、安裝後配置之root密碼修改

root初始密碼自動生成，默認存放在/data/mysql/mysql.err 中。修改root密碼的方式有如下兩種，隨便哪一個都行
若是沒有

vi /etc/my.cnf
2.在[mysqld]中添加
skip-grant-tables
例如：
[mysqld]
這句話加上表示不使用密碼進入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、修改庫表數據方式

先登錄mysql服務器

mysql -uroot -p # 進入mysql
Enter password:

通常mysql版本

mysql>  set password=password('root'); # 這裏是將密碼設置爲root123 ,請根據實際修改

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，全部咱們要用如下修改進行重置密碼
update user set authentication_string=password('123456') where user='root';
若是是5.7如下的版本修改密碼是這樣的
update user set password=password('123456') where user='root';

七、設置遠程訪問

先登錄mysql服務器，受權root用戶能夠遠程登錄

mysql -uroot -p # 進入mysql
grant all PRIVILEGES on *.* to root@'%' identified by 'root'; # 這裏的root是你的密碼
Query OK, 0 rows affected (0.00 sec)# 顯示這一句就是對的
flush privileges;
Query OK, 0 rows affected (0.00 sec)# 顯示這一句就是對的

若是報錯You must reset your password using ALTER USER statement before executing this statement.
則再次設置密碼便可
SET PASSWORD = PASSWORD('root');
grant all PRIVILEGES on *.* to root@'%' identified by 'root';
flush privileges;
``
這樣就能夠鏈接了，使用工具鏈接ip:3306

## 八、額外命令

​```bash
CREATE USER 'mysql'@'%' IDENTIFIED BY 'mysql' # 建立mysql用戶
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'mysql'@'%'; # 給mysql用戶全部權限
FLUSH PRIVILEGES;

八、給MySQL用戶全部權限

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`@`%`;

經常使用命令

sudo service mysql stop # 中止
sudo service mysql start # 啓動
sudo service mysql restart #重啓
sudo service mysql status # 查看狀態
