Custom installation path step record for Mysql 5.5.56 (Binary Package installation), mysql5.5.56

Custom installation path step record for Mysql 5.5.56 (Binary Package installation), mysql5.5.56

Installation path:/application/mysql-5.5.56

1. Preparations

Mysql dependency

libaioyum install -y libaio

Create a mysql user and execute mysql as the user

useradd -s /bin/false -M mysql

Download and decompress the mysql Binary Package

cd /toolswget https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.56-linux-glibc2.5-x86_64.tar.gztar -zxf mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz -C /application/

Switch to the/application directory, shorten the mysql folder name, and provide a soft link to the mysql directory.

cd /application/mv mysql-5.5.56-linux-glibc2.5-x86_64/ mysql-5.5.56ln -s mysql-5.5.56/ mysql

Recursively sets the group and user of the mysql directory

chown -R mysql:mysql mysql-5.5.56/

2. mysql directory operations

cd mysql

Initialize Database

A data directory is generated in the mysql directory to store the database directory.

./scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data/ --user=mysql

Change user and group

chown -R root .chown -R mysql data

Except the user of the data directory under the mysql directory, the user of all other files is changed to root.

Copy configuration file

cp support-files/my-medium.cnf /etc/my.cnf

Copy the mysql configuration file to my. cnf in the/etc/directory.

Modify configuration file

sed -i 28i'log-error=/application/mysql/data/mysqld.error' /etc/my.cnf

Insert a line in the configuration file to perform configuration error logs.

/etc/my.cnf Content:# Example MySQL config file for medium systems.## This is for a system with little memory (32M - 64M) where MySQL plays# an important part, or systems up to 128M where MySQL is used together with# other programs (such as a web server)## MySQL programs look for option files in a set of# locations which depend on the deployment platform.# You can copy this option file to one of those# locations. For information about these locations, see:# http://dev.mysql.com/doc/mysql/en/option-files.html## In this file, you can use all long options that a program supports.# If you want to know which options a program supports, run the program# with the "--help" option.# The following options will be passed to all MySQL clients[client]#password = your_passwordport = 3306socket = /tmp/mysql.sock# Here follows entries for some specific programs# The MySQL server[mysqld]port = 3306log-error=/application/mysql/data/mysqld.errorsocket = /tmp/mysql.sockskip-external-lockingkey_buffer_size = 16Mmax_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 - 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 =## 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 = /usr/local/mysql/data#innodb_data_file_path = ibdata1:10M:autoextend#innodb_log_group_home_dir = /usr/local/mysql/data# You can set .._buffer_pool_size up to 50 - 80 %# of RAM but beware of setting memory usage too high#innodb_buffer_pool_size = 16M#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 = 50[mysqldump]quickmax_allowed_packet = 16M[mysql]no-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

Copy the Startup Program

cp support-files/mysql.server /etc/init.d/mysql

Copy the mysql Startup Program to the/etc/init. d/directory to start the program.

Edit the Startup File and configure the startup directory

Method 1:

The idea is to assign values to the variables provided by the configuration file. It is troublesome.

sed -i ':a;N;$!ba;s/basedir=\ndatadir=/basedir=\/application\/mysql\ndatadir=\/application\/mysql\/data/g' /etc/init.d/mysqlsed -i ':a;N;$!ba;s/mysqld_pid_file_path=\n/mysqld_pid_file_path=\/application\/mysql\/data\/mysqld.pid\n/g' /etc/init.d/mysql

Equivalent to dividing 45 and 46 rows

basedir=datadir=mysqld_pid_file_path=

Replace

basedir=/application/mysqldatadir=/application/mysql/datamysqld_pid_file_path=/application/mysql/data/mysql.pid

Method 2 (recommended ):

The idea is to replace the default address of the script (/usr/local/mysql) with the custom path (/application/mysql) without assigning a value to the variable.

sed -i 's#/usr/local/mysql#/application/mysql#g' /etc/init.d/mysql

Mysql can be started properly after installation.

3. End later

Command to create a soft link

Create a soft link from the mysql command to the environment variable directory so that you can find the corresponding command in the Variable

ln -s /application/mysql/bin/* /usr/local/sbin

Set and modify passwords

Set the password for the first time:

mysqladmin -u'' password ''

Example:

mysqladmin -u'root' password 'PassWord'

Change the password later:

mysqladmin -u'' -p'' password ''

Example:

mysqladmin -u'root' -p'PassWord' password 'NewPassWord'

Log on to mysql

$ Mysql-u 'root'-p' PassWord 'Welcome to the MySQL monitor. commands end with; or \ g .... mysql> # successfully log on to the mysql console $ mysql-uroot-pPassWordWelcome to the MySQL monitor. commands end with; or \ g .... mysql> # successfully log on to the mysql console $ mysql-u 'root'-pEnter password: # enter the user's password Welcome to the MySQL monitor. commands end with; or \ g ....

Mysql> # log on to the mysql Console

$ Mysql-uroot-pEnter password: # enter the user's password Welcome to the MySQL monitor. Commands end with; or \ g ....

Mysql> # log on to the mysql Console

Type quit or Ctrl + d to exit the mysql Environment

mysql> quitBye[root@www mysql]#ormysql> ^DBye[root@www mysql]#

4. Common commands

mysql -u'root' -p'PassWord'mysql -uroot -pPassWordmysql -u'root' -pmysql -uroot -p
