【mysql】MySQL5.7二进制方式安装（mysql5.7&CentOS6.8）----模拟生产库
MySQL5.7二进制方式安装（mysql5.7&CentOS6.8）----模拟生产库
--将mysql二进制包上传到服务器并解压
先创建/u01/mysql，然后将安装包上传到这里
# mkdir -p /u01/mysql
解压安装包到/u01/mysql目录
# tar zxvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz -C /u01/mysql #注意如果需要解压到指定的目录需要加-C参数
更改文件夹名
# mv /data/mysql-5.7.21-linux-glibc2.12-x86_64 /u01/mysql/mysql5.7
--安装依赖包，使用yum安装，故前提条件是网络源的yum方式可用
# yum -y install libaio
--创建mysql用户和组
# groupadd mysql
# useradd -g mysql mysql
# passwd mysql
--配置数据库目录
# mkdir -p /u01/mysql/{myetc,mydata,logs}
# chown mysql:mysql -R /u01/mysql
--配置环境变量
# echo "export PATH=$PATH:/u01/mysql/mysql5.7/bin" >> /etc/profile
# source /etc/profile
--配置my.cnf文件---适当调整 innodb_buffer_pool 大小就可以了。（建议物理内存的50-80%）
# vi /u01/mysql/myetc/my.cnf

注意：MySQL 5.7.2新增log_timestamps参数，该参数主要是控制error log、genera log等记录日志的显示时间。
--初始化
# cd /u01/mysql/mysql5.7/bin
# ./mysqld --defaults-file=/u01/mysql/myetc/my.cnf --basedir=/u01/mysql/mysql5.7 --datadir=/u01/mysql/mydata --user=mysql --initialize
此时会生成一个root初始化密码
# grep 'password' /u01/mysql/logs/error.log
--启动数据库
# cd /u01/mysql/mysql5.7/bin
# ./mysqld_safe --defaults-file=/u01/mysql/myetc/my.cnf &
注：启动建议使用mysqld_safe启动，后面加&是后台运行
--登录数据库与修改root密码
# cd /u01/mysql/mysql5.7/bin
# ./mysql -uroot -p
输入上面查到的root初始化密码
修改root密码，设置密码为永不过期
mysql> set password = 'root123';
mysql> alter user 'root'@'localhost' password expire never;
mysql> flush privileges;
--关闭数据库
# mysqladmin -uroot -p密码 shutdown
--查看mysql进程是否存在
# ps -ef|grep mysql
