Step a: downloading the installation package, open Mysql official website, find the corresponding
Download path is as follows: https://downloads.mysql.com/archives/community/
wget https://downloads.mysql.com/archives/get/file/mysql-5.7.27-linux-glibc2.12-x86_64.tar.gz -O /usr/local/src/mysql-5.7.27-linux-glibc2.12-x86_64.tar.gz
Step two: downloading dependencies, Centos7 no installation comes
[centos702 the root @ 21 is : 56 is : . 19 ]: / usr / local / the src # yum -Y the install libaio loaded plug: fastestmirror, Langpacks Loading Mirror SPEEDS cached from the hostfile * Base: mirrors.aliyun.com * EPEL: mirrors.aliyun .com * Extras: mirrors.aliyun.com * the Updates: mirrors.aliyun.com package libaio - 0.3 . 109 - 13 .el7.x86_64 installed and the latest version without any treatment
Step Three: extracting installation package
[root@centos702 21:58:45]:/usr/local/src #tar -zxvf mysql-5.7.27-linux-glibc2.12-x86_64.tar.gz
Step Four: Create a database user, move the database files to the location you want to put, and to create a mysql data directory, last modified owner as Mysql
[root@centos702 21:59:26]:/usr/local/src #useradd -M -s /sbin/nologin -r mysql
#mv /usr/local/src/mysql-5.7.27-linux-glibc2.12-x86_64 /home/data/mysql [root@centos702 22:02:09]:/usr/local/src #mkdir -p /home/data/mysql [root@centos702 22:02:18]:/usr/local/src #chown -R mysql.mysql /home/data/mysql
Step Five: initialize the database
[root@centos702 22:04:56]:/home/data #/home/data/mysql/bin/mysqld --initialize --user=mysql --basedir=/home/data/mysql --datadir=/home/data/mysql/data 2019-11-09T14:06:56.634380Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2019-11-09T14:06:57.063698Z 0 [Warning] InnoDB: New log files created, LSN=45790 2019-11-09T14:06:57.142365Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2019-11-09T14:06:57.200813Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 30cc7a37-02fa-11ea-a548-000c29cbc202. 2019-11-09T14:06:57.202254Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed ' CAN BE Not the Opened. 2019 - . 11 -09T14: 06 : 57 is .203612Z . 1 [Note] A Temporary Generated IS password for the root @ localhost: KaELVb2yol < . 4 # The temporary password is generated for the first time landing, need to re-edit after landing
Step Six: Create a profile, create a profile only common here
cat > /etc/my.cnf <<EOF [mysqld] basedir=/home/data/mysql datadir=/home/data/mysql/data port=3306 socket=/home/data/mysql/mysql.sock character-set-server=utf8 log-error=/var/log/mysqld.log pid-file=/tmp/mysqld.pid [mysql] socket=/home/data/mysql/mysql.sock [client] socket=/home/data/mysql/mysql.sock EOF
Step 7: Configuring environment variables, and refresh
cat >/etc/profile.d/mysql.sh <<EOF export PATH=/home/data/mysql/bin:\$PATH EOF
source /etc/profile.d/mysql.sh
Step Eight: startup script generation, and start the mysql
[root@centos702 22:14:40]:/home/data #cp /home/data/mysql/support-files/mysql.server /etc/init.d/mysql [root@centos702 22:16:42]:/home/data #chmod +x /etc/init.d/mysql
[root@centos702 22:17:55]:/home/data #vim /etc/init.d/mysql
# Modify mysql startup configuration file, and the specified datadir basedir path, if not specified, the default is / usr / local / mysql [centos702 the root @ 22 is : 18 is : 31 is ]: / Home / Data # Sed -i ' 46S basedir = # # = the basedir / Home / Data / MySQL # ' /etc/init.d/ MySQL [centos702 the root @ 22 is : 20 is : 15 ]: / Home / Data # Sed -n ' 46p ' /etc/init.d/ MySQL the basedir = / Home / Data / MySQL [centos702 the root @ 22 is : 20 is : 30 ]: / Home /data #sed -i '47s#datadir=#datadir=/home/data/mysql/data#' /etc/init.d/mysql [root@centos702 22:21:13]:/home/data #sed -n '47p' /etc/init.d/mysql datadir=/home/data/mysql/data
#启动mysql [root@centos702 22:23:54]:/home/data # /etc/init.d/mysql start Starting MySQL. SUCCESS!
Step 9: Log mysql, and change passwords
[root@centos702 22:26:28]:/home/data #mysql -uroot -p'KaELVb2yol<4' mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor.
