1. Download
Log in to the mysql official website download page: https://dev.mysql.com/downloads/ , select the Linux system source version to download.
2. Old version
Enter the system and use the following command to check whether mysql is installed in the system:
rpm -qa | grep mysql
If the returned result contains mysql or related components, you can use the rpm -e command to uninstall.
rpm -e xxxxx //Normal uninstall mode rpm -e --nodeps xxxxx // Forced uninstall mode, which ignores associated component prompts
3. Installation
1) Install the components needed to compile the code
yum -y install make gcc-c++ cmake bison-devel ncurses-devel bison boost
2) Unzip mysql
Upload mysql to the /usr/local/software directory
chmod +x mysql-boost-5.7.18.tar.gz
Unzip the installation package
tar -zxvf mysql-boost-5.7.18.tar.gz
3) Create mysql user
groupadd mysql useradd -r -g mysql -s /bin/false mysql
4) Compile
cd mysql-5.7.18 cmake \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_DATADIR=/usr/local/mysql/data \ -DSYSCONFDIR=/etc \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \ -DMYSQL_TCP_PORT=3306 \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DEXTRA_CHARSETS=all \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DWITH_BOOST=/usr/local/boost
Execute after finishing:
make&make install
5) Initialize the database
cd /usr/local/mysql scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
6) Configure mysql
vi /etc/profile
Add to the file:
PATH=/usr/local/mysql/bin:$PATH export PATH
Then execute:
source /etc/profile
Finally, copy the mysql startup script and start mysql
cp support-files/mysql.server /etc/init.d/mysql chkconfig mysql on service mysql start
This will randomly start mysql.
7) Configure users
Initialize user password
mysql -uroot
SET PASSWORD = PASSWORD('123456');
Configure access rights
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '654321' WITH GRANT OPTION;
The password for accessing the external address of the root user can be different from the local one, or it can be configured as another user.
