centos7.2 offline installation mysql5.7.18.tar.gz

Because of network isolation, MySQL cannot be installed using yum. Here is a method to manually install MySQL offline on a Linux server.

Purpose

Offline installation of MySQL service server: centos7.2, configure local yum source
mysql version:mysql5.7.18

step

1. Download the installation package mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz and transfer the installation package to the /tmp directory of the destination server
2. The my.cnf file (see the end of the article) is transferred to the /tmp directory of the destination server
3. Create users and corresponding folders:

# prepare
groupadd mysql
useradd -r -g mysql -s /bin/false mysql
yum install -y autoconf
mkdir /apps
mkdir /logs
mkdir /data
mkdir -p /data/mysql7006/data && chown -R mysql:mysql /data/mysql7006
mkdir /logs/mysql7006 && chown -R mysql:mysql /logs/mysql7006
touch /logs/mysql7006/error-log.err && chown -R mysql:mysql /logs/mysql7006/error-log.err

4. Installation

cd /tmp
tar zxvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.18-linux-glibc2.5-x86_64 mysql
mv mysql /apps/mysql
cp my.cnf /apps/mysql/

chown -R mysql:mysql /apps/mysql/
# Initialize the database,
cd /apps/mysql
./bin/mysqld --initialize --user=mysql --basedir=/apps/mysql/ --datadir=/data/mysql7006/data/

A default password will be generated during the initialization process. Remember to write it down for later modification.

5. Register the service (optional)

# Modify support-files/mysql.server as needed
cp support-files/mysql.server /etc/init.d/mysql
systemctl start mysql.service

# Add startup chkconfig mysql.server on

6. Start the database /apps/mysql/bin/mysqld_safe --defaults-file=/apps/mysql/my.cnf &

7. Change the default password:

/apps/mysql/bin/mysqladmin -u root password 'password' --port=7006 --socket=/data/mysql7006/mysql.sock -p
# Clear the Linux history record after modification history -c

# Login test:
/apps/mysql/bin/mysql -u root --port=7006 --socket=/data/mysql7006/mysql.sock -p

8. Firewall, empowerment (as needed)

# Firewall firewall-cmd --zone=public --add-port=7006/tcp --permanent
systemctl restart firewalld
firewall-cmd --zone=public --query-port=7006/tcp
#Give the login user the right to use mysql;
grant all privileges on *.* to user@'ip' identified by "password";
flush privileges;
select host,user,password from user;

9. Local hidden password login (optional)

## Use mysql_config_editor to create a login file /apps/mysql/bin/mysql_config_editor set --login-path=root_pass --user=root --port=7006 --socket=/data/mysql7006/mysql.sock --password
## Enter password:******
## The file will be encrypted and stored in the user's root directory.mylogin.cnf
/apps/mysql/bin/mysql_config_editor print --all
## Next time you log in, just type:
/apps/mysql/bin/mysql --login-path=root_pass

# Make it easier: set alias
# Open file .bashrc, add alias db7006='/apps/mysql/bin/mysql --login-path=root_pass'
# Then exit execution:
source .bashrc
## Next time you log in, just type:
db7006
