同一臺機器安裝多個MySQL服務

在同一個服務器上面安裝多個MySQL服務，甚至是安裝多個不一樣版本（好比5.7和5.七、5.7和8.0.12），關鍵在於區分安裝目錄、數據目錄和使用端口等。

能夠下面步驟

• 安裝MySQL1

wget https://mirrors.163.com/mysql/Downloads/MySQL-5.7/mysql-5.7.22-macos10.13-x86_64.tar.gz

tar -xzvf mysql-5.7.22-macos10.13-x86_64.tar.gz

mv mysql-5.7.22-macos10.13-x86_64 ../mysql5.7.22
cd ../mysql5.7.22/

mkdir data
cd data
mkdir binlog data innodb tmp

cd ../
vi my5.cnf

bin/mysqld --defaults-file=/Users/liwenjie01/mysql5.7.22/my5.cnf --initialize-insecure --user=liwenjie01 --basedir=/Users/liwenjie01/mysql5.7.22 --datadir=/Users/liwenjie01/mysql5.7.22/data/data

bin/mysqld_safe --defaults-file=/Users/liwenjie01/mysql5.7.22/my5.cnf --user=liwenjie01 &

bin/mysql -S /Users/liwenjie01/mysql5.7.22/data/mysql5.sock -uroot -p

create user mysql@"%" identified by "mysql";
grant all privileges on *.* to mysql@"%" with grant option;
flush privileges;

bin/mysql -S /Users/liwenjie01/mysql5.7.22/data/mysql5.sock -umysql -pmysql

• 第二個MySQL服務

安裝第二個MySQL步驟和第一個幾乎同樣：

wget https://mirrors.163.com/mysql/Downloads/MySQL-5.7/mysql-5.7.22-macos10.13-x86_64.tar.gz

tar -xzvf mysql-5.7.22-macos10.13-x86_64.tar.gz

mv mysql-5.7.22-macos10.13-x86_64 ../mysql5.7.22_2
cd ../mysql5.7.22_2/

mkdir data
cd data
mkdir binlog data innodb tmp

cd ../
vi my5.cnf

bin/mysqld --defaults-file=/Users/liwenjie01/mysql5.7.22_2/my5.cnf --initialize-insecure --user=liwenjie01 --basedir=/Users/liwenjie01/mysql5.7.22_2 --datadir=/Users/liwenjie01/mysql5.7.22_2/data/data

bin/mysqld_safe --defaults-file=/Users/liwenjie01/mysql5.7.22_2/my5.cnf --user=liwenjie01 &

bin/mysql -S /Users/liwenjie01/mysql5.7.22_2/data/mysql5.sock -uroot -p

create user mysql@"%" identified by "mysql";
grant all privileges on *.* to mysql@"%" with grant option;
flush privileges;

bin/mysql -S /Users/liwenjie01/mysql5.7.22_2/data/mysql5.sock -umysql -pmysql
