Summary: SuSE11sp3 64-bit operating system, MySQL5.7.22 rpm installation package

The installation of version 5.7 is different from the previous version, which should be noted.

Note: kingtry is my hostname

I. Environmental preparation

Operating system: SuSE version 11sp3re64-bit

Kingtry:~ # uname-aLinux kingtry 3.0.76-0.11-default # 1 SMP Fri Jun 14 08:21:43 UTC 2013 (ccab990) x86 "64 x 86" 64 x86 "64 GNU/Linuxkingtry:~ # cat / etc/SuSE-release SUSE Linux Enterprise Server 11 (x86" 64) VERSION = 11PATCHLEVEL = 3

Second, check whether MySQL has been installed

My computer shows that I have previously installed version 5.1.73 of mysql, which is relevant to the actual situation.

Kingtry:~ # rpm-qa | grep-I mysqllibmysqlclient_r15-5.0.96-0.6.1libqt4-sql-mysql-4.6.3-5.25.4MySQL-client-community-5.1.73-1.sles11MySQL-server-community-5.1.73-1.sles11

Note that the output MySQL-*, indicates that it has been installed. The beginning of lib can be ignored.

Enter the following command to delete:

Kingtry:~ # rpm-e MySQL-client-community-5.1.73-1.sles11kingtryMySQL-client-community-5.1.73 ~ # rpm-e MySQL-server-community-5.1.73-1.sles11

III. Software preparation

Mysql-community-common-5.7.22-1.sles11.x86_64.rpmmysql-community-libs-5.7.22-1.sles11.x86_64.rpmmysql-community-client-5.7.22-1.sles11.x86_64.rpmmysql-community-server-5.7.22-1.sles11.x86_64.rpm

IV. Install the software

Note: 4 rpm installation packages, which have dependencies, can be installed in the following order.

Kingtry:~ # rpm-ivh mysql-community-common-5.7.22-1.sles11.x864th 64.rpmkingtryivh mysql-community-common-5.7.22 ~ # rpm-ivh mysql-community-libs-5.7.22-1.sles11.x86room64.rpmkingtryVera ~ # rpm-ivh mysql-community-client-5.7.22-1.sles11.x86room64.rpmkingtryrpm ~ # rpm-ivh mysql-community-server-5.7.22-1.sles11.x86_64.rpm

If you want to query the detailed list of installation files of the rpm package and the actual storage path of each file, you can query it with the command rpm-ql, such as:

Kingtry:~ # rpm-ql mysql-community-client-5.7.22-1.sles11/usr/bin/mysql/usr/bin/mysql_config_editor/usr/bin/mysqladmin/usr/bin/mysqlbinlog/usr/bin/mysqlcheck/usr/bin/mysqldump/usr/bin/mysqlimport/usr/bin/mysqlpump/usr/bin/mysqlshow/usr/bin/mysqlslap/usr/share/doc/packages/mysql-community-client/usr/share/doc/packages/mysql-community-client/COPYING/usr/share / doc/packages/mysql-community-client/README/usr/share/man/man1/mysql.1.gz/usr/share/man/man1/mysql_config_editor.1.gz/usr/share/man/man1/mysqladmin.1.gz/usr/share/man/man1/mysqlbinlog.1.gz/usr/share/man/man1/mysqlcheck.1.gz/usr/share/man/man1/mysqldump.1.gz/usr/share/man/man1/mysqlimport.1.gz/usr/share/man / man1/mysqlpump.1.gz/usr/share/man/man1/mysqlshow.1.gz/usr/share/man/man1/mysqlslap.1.gz

5. Modify the configuration file / etc/my.cnf

The / etc/my.cnf file is automatically generated after the software is installed. The actual content of the file is relatively simple. The following is what I modified.

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html [client] # password = your_passwordport = 3306socket = / data/mysql/mysql.sockdefault-character-set=utf8# Here follows entries for some specific programs# The MySQL server [mysqld] port = 3306datadir = / data/mysql/datatmpdir = / data/mysql/tmpsocket = / data/mysql/mysql.sockcharacter-set-server = utf8collation-server = utf8_general_cipid-file = / data/mysql/mysql.piduser = mysql explicit_defaults_for_timestamplower_case_table_names = 1max_connections = 1000back_log = 1024open_files_limit = 10240table_open_cache = 5120 # bind-address = 127.0.0.1 # skip-name-resolveskip-external-lockinglocal-infile = 1 key_buffer_size = 32Mmax_allowed_packet = 1Mtable_open_cache = 64sort_buffer_size = 512Knet_buffer_length = 8Kread_buffer_size = 256Kread_rnd_buffer_size = 512Kmyisam_sort _ buffer_size = 8m # Don't listen on a TCP/IP port at all.

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-and different from the master) # defaults to 2 if master-host is set# but will not function as a slave if omitted#server-id = 2percent # The replication master for this slave-required#master-host = # # The username the slave will use for authentication when connecting# to the master- required#master-user = # # The password the slave will authenticate with when connecting to# the master- required#master-password = # # The port the master is listening on.# optional-defaults to 3306#master-port = # # binary logging-not required for slaves But recommended#log-bin=mysql-bin # Uncomment the following if you are using InnoDB tables#innodb_data_home_dir = / var/lib/mysqlinnodb_data_file_path = ibdata1:10M:autoextend#innodb_log_group_home_dir = / var/lib/mysql# You can set.. _ buffer_pool_size up to 50-80% # of RAM but beware of setting memory usage too highinnodb_buffer_pool_size = 256M#innodb_additional_mem_pool_size = 2M# Set.. _ log_file _ size to 25% of buffer pool size#innodb_log_file_size = 5M#innodb_log_buffer_size = 8M#innodb_flush_log_at_trx_commit = 1#innodb_lock_wait_timeout = 50innodb_buffer_pool_instances = 2innodb_read_io_threads = 8innodb_write_io_threads = 8innodb_purge_threads = 1 slow_query_log = 1long_query_time = 10log-queries-not-using-indexes log-error = / data/mysql/mysql.err expire-logs- Days = 10 [mysqldump] quickmax_allowed_packet = 512Mnet_buffer_length = 16384 [mysql] auto-rehash# Remove the next comment character if you are not familiar with SQL#safe-updates [myisamchk] key_buffer_size = 20Msort_buffer_size = 20Mread_buffer = 2Mwrite_buffer = 2m [mysqlhotcopy] interactive-timeout

VI. Initialize the database

Note: the database is no longer created by default after the version 5.7 rpm package is installed, and the mysql service will not start automatically. But it still automatically increases the system user mysql.

Kingtry:~ # mkdir-p / data/mysql/ {data,tmp} # create a directory to store data files. The space kingtry:~ # chown-R mysql/data/ mysql kingtry:~ # mysqld-- initialize-- datadir=/data/mysql/data/-- user=mysql # cannot be initialized between data and tmp

After successful initialization, the default password for root is written to the file: / data/mysql/mysql.err, as follows:

A temporary password is generated for root@localhost: _ tVUgaq%P25Q # this is the default password for root

7. Start the mysql service

Kingtry:~ # service mysql start doneStarting MySQL. Donekingtry:~ #

Check to see if the MySQL service has been started:

Kingtry:~ # netstat-nat | grep 3306

VIII. Root password modification after installation

The initial root password is generated automatically and is stored in / data/mysql/mysql.err by default. There are two ways to change the root password, either of which is fine:

1. Command mode

Kingtry:~ # mysqladmin-u root-p password 'root123' Enter password:

2. Modify the database table data mode

Log in to MySQL server first

Mysql > set password=password ('root123')

The firewall allows port 3306.

Kingtry:~ # vi / etc/sysconfig/SuSEfirewall2

Add 3306 ports to FW_SERVICES_EXT_TCP. If there are other ports, spaces are separated, such as:

FW_SERVICES_EXT_TCP= "21 22 3306"

Restart the firewall:

# rcSuSEfirewall2 restart

10. Set up remote access

Log in to the MySQL server first, and authorized root users can log in remotely

Mysql > grant all PRIVILEGES on *. * to root@'%' identified by 'root123'; Query OK, 0 rows affected (0.00 sec) mysql > flush privileges;Query OK, 0 rows affected (0.00 sec) mysql >

Note: it is best for a production environment to allow root remote access only on machines with a specific IP.

Instructions on how to install RPM:

What is easy to see is simple.

But the disadvantage is also prominent: it is not flexible, and only one set of MySQL can be installed in a single system managed by RPM.
