二进制安装

解压二进制安装包

[root@PBSZBXPROXYDB tools]# tar zxvf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz -C /opt/
[root@PBSZBXPROXYDB tools]# ln -s /opt/mysql-5.7.17-linux-glibc2.5-x86_64/ /usr/local/mysql
# Config PATH
[root@PBSZBXPROXYDB ~]# echo 'export PATH=/usr/local/mysql/bin:$PATH' >> ~/.bash_profile
[root@PBSZBXPROXYDB ~]# source ~/.bash_profile

创建用户：

[root@PBSZBXPROXYDB ~]# groupadd mysql 
[root@PBSZBXPROXYDB ~]# useradd -r -g mysql -s /bin/false mysql

安装依赖包：

yum -y install libaio libaio-devel

复制启动脚本。

注意：我们不使用这个安装包里自带的服务脚本，而是使用下面提供的脚本，因而该步骤可不执行。

[root@PBSZBXPROXYDB ~]# cd /opt/mysql/
[root@PBSZBXPROXYDB mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@PBSZBXPROXYDB mysql]# chmod +x /etc/init.d/mysqld

创建数据目录并进行授权。

[root@PBSZBXPROXYDB ~]# mkdir -p /data/mysql/mysql3306/{data,logs,tmp}
[root@PBSZBXPROXYDB ~]# chown -R mysql:mysql /usr/local/mysql/
[root@PBSZBXPROXYDB ~]# chown -R mysql:mysql /data/mysql/mysql3306/

上传配置文件，该配置文件是事先准备好的（请注意配置文件的位置）：

[root@PBSZBXPROXYDB ~]# vim /data/mysql/mysql3306/mysql3306.cnf

数据库初始化：

/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/mysql3306/mysql3306.cnf --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/mysql3306/data

注意：使用--initialize-insecure参数的目的是不初始化root用户密码，因而不会生成一个随机密码。

创建启停止脚本：

[root@PBSZBXPROXYDB ~]# vim /data/mysql/mysql3306/start.sh
/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/mysql3306/mysql3306.cnf &
[root@PBSZBXPROXYDB ~]# vim /data/mysql/mysql3306/stop.sh
/usr/local/mysql/bin/mysqladmin -uroot -psuixingpay123 shutdown

注意：上面的root用户的密码要依据实际情况进行修改。

启动数据库：

[root@PBSZBXPROXYDB ~]# sh /data/mysql/mysql3306/start.sh

服务启动后就能够直接登录了（因为未初始化root的密码，因而无需输入密码，直接登录）：

[root@PBSZBXPROXYDB ~]# mysql -uroot
