SUSE12Sp3安装配置.net core 生产环境(5)-RPM安装mysql5.7

程序员文章站 2022-05-03 23:01:52
1、将以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.sles1 ......
1、将以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

2、安装软件
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

如果想查询rpm包详细的安装文件列表及每个文件的实际存储路径,可通过命令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

/usr/bin/mysqldump

/usr/bin/mysqlpump
/usr/bin/mysqlshow
/usr/bin/mysqlslap

3、修改配置文件/etc/my.cnf
sudo vi /etc/my.cnf

内容如下(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 = xxxx
port = 3306

tmpdir = /data/mysql/tmp

# 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!

# 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

# 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

4、初始化

注:5.7版本的rpm包安装之后默认不再创建数据库,mysql服务也不会自动启动。但是它还是自动增加了系统用户mysql。

sudo mkdir -p /data/mysql/{data,tmp}       #创建存放数据文件目录,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

初始化成功之后,会将root的默认密码写入文件:/data/mysql/mysql.err 中,如下:

a temporary password is generated for root@localhost: _tvugaq%p25q   #这就是root的默认密码
5、启动mysql服务即可
sudo service mysql start

检查mysql服务是否已经启动:

netstat -nat | grep 3306
6、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密码的方式有以下两种,随便哪个都行

1、命令方式

kingtry:~ # mysqladmin -u root -p  password 'root123' 
enter password:

2、修改库表数据方式

先登陆mysql服务器

mysql>  set password=password('root123') # 这里是将密码设置为root123 ,请根据实际修改
7、设置远程访问

先登陆mysql服务器,授权root用户可以远程登陆

mysql -uroot -p # 进入mysql
grant all privileges on *.* to root@'%' identified by 'root123'; # 这里的root123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

这样就可以连接了,使用工具连接ip:3306
