1 單節(jié)點(diǎn)部署

1.1 tar.gz包安裝方式

1）安裝依賴

yum -y install gcc glibc libaio libstdc++ libstdc libncurses ld-linux

2）準(zhǔn)備軟件包，解壓

tar -xvf Percona-Server-5.7.19-17-Linux.x86_64.ssl101.tar.gz -C /usr/local/

?

3）建立軟鏈接

ln -s /usr/local/Percona-Server-5.7.19-17-Linux.x86_64.ssl101 /usr/local/mysql

?

4）添加mysql 用戶與用戶組

groupadd mysql
useradd -r -g mysql mysql

?

5）修改目錄屬性權(quán)限

chown -R mysql:mysql  /usr/local/mysql

?

6）添加環(huán)境變量

echo 'export PATH=/usr/local/mysql/bin:$PATH' >> /etc/profile
source /etc/profile

7）創(chuàng)建data和binlog 目錄，并修改權(quán)限

mkdir -p /mysql/{data,binlog}
chown -R mysql:mysql /mysql/

?

8）創(chuàng)建配置文件my.cnf
