Several methods of installing Mysql in Linux

Several ways of database installation

1, yum online installation

(1) Download the official yum repository of MYSQl

[[email protected]~]#dnf install https://repo.mysql.com//mysql80-community-release-el9-1.noarch.rpm

(2) Install MYSQL service

[[email protected] ~]# dnf install mysql-server

(3) Start the service

[[email protected] ~]# systemctl start mysqld

(4) View the initial password

[[email protected] ~]# grep 'temporary password' /var/log/mysqld.log

(5) Log in with the initial password

[[email protected] ~]# mysql -uroot -pEnter password: temporary password

(6) Change the password (note: uppercase and lowercase plus symbols)

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'XXXXXXXXX';

2, rpm local installation

(1) Download the rpm package from the MYSQL official website

(2) Transfer the rpm package from windows to linux via ftp

(3) Unzip the rpm package

[[email protected] ~]# tar -xzvf mysql-8.0.30-1.el9.x86_64.rpm-bundle.tar

(4) dnf/yum for installation

[[email protected] ~]# dnf localinstall mysql-community-server-8.0.30-1.el9.x86_64.rpm \mysql-community-client-8.0.30-1.el9.x86_64.rpm\mysql-community-common-8.0.30-1.el9.x86_64.rpm\mysql-community-icu-data-files-8.0.30-1.el9.x86_64.rpm\mysql-community-libs-8.0.30-1.el9.x86_64.rpm\mysql-community-client-plugins-8.0.30-1.el9.x86_64.rpm

(5) Start the service

[[email protected] ~]# systemctl start mysqld

(6) View the initial password

[[email protected] ~]# grep 'temporary password' /var/log/mysqld.log

(7) Log in with the initial password

[[email protected] ~]# mysql -uroot -pEnter password: temporary password

(8) Change the password (note: uppercase and lowercase plus symbols)

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'XXXXXXXXX';

3. Install MYSQL from source code

(1) Create a directory mysql and transfer the source package to this directory and decompress it

[[email protected] ~]# mkdir /mysql[[email protected] ~]# mv mysql-boost-8.0.29.tar.gz /mysql/[[email protected] ~]# cd /mysql/[[email protected] mysql]# tar xvf mysql-boost-8.0.29.tar.gz

(2) Enter the directory after the decompression is completed, and add the group and group members

[[email protected] mysql]# cd mysql-8.0.29/[[email protected] mysql-8.0.29]# groupadd mysql[[email protected] mysql-8.0.29]# useradd -r -g mysql -s /bin/false mysql

(3) Create a bld file, switch to this file and download the packages needed for the next compilation

[[email protected] mysql-8.0.29]# mkdir bld[[email protected] mysql-8.0.29]# cd bld/[[email protected] bld]# dnf install cmake gcc gcc-c++[[email protected] bld]# yum install gcc-toolset-11-gcc gcc-toolset-11-gcc-c++ gcc-toolset-11-binutils ncurses-devel libtirpc-devel

(4) At this time, the download will report an error, because there is no rpcgen package in the local warehouse, which requires us to download it by ourselves

[[email protected] bld]# rpm -i rpcgen-1.3.1-4.el8.x86_64.rpm

(5) Start cmake

[[email protected] bld]# cmake .. -DDOWNLOAD_BOOST=1 -DWITH_BOOST=../boost/boost_1_77_0/

(6) make; mark install

[[email protected] bld]# make;make install

(7) After method 1 or 2, start the service, check the initial password, log in, and change the password.
