二进制部署MySQL5.7
这个文档用于基础解释，后面通过ansible的自动化对MySQL单实例进行安装部署。
1、解压文件
# tar zxvf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local
2、重命名文件名称
# cd /usr/local
# mv mysql-5.7.22-linux-glibc2.12-x86_64/ mysql/
3、新建mysql用户
# groupadd mysql
# useradd -g mysql mysql
4、设置用户操作系统资源的限制
# vi /etc/security/limits.conf
mysql soft nproc 65536
mysql hard nproc 65536
mysql soft nofile 65536
mysql hard nofile 65536
- 验证limit是否生效
su - mysql
ulimit -a
5、创建MySQL数据目录及赋予相应权限
#cd /data/
#mkdir -p /data/mysqldata/{3306/{data,tmp,binlog,innodb_ts,innodb_log},backup,scripts}
#chown -R mysql:mysql mysqldata
6、配置my.cnf
#su - mysql
[client]
port = 3306
socket = /data/mysqldata/3306/mysql.sock
# The MySQL server

port = 3306

7、初始化数据库mysql
$/usr/local/mysql/bin/mysqld --defaults-file=/data/mysqldata/3306/my.cnf --initialize-insecure --user=mysql
备注:
--initialize生成一个随机密码
--initialize-insecure不生成随机密码
8、启动mysql服务
$/usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysqldata/3306/my.cnf --user=mysql &
9、配置mysql环境变量
[mysql@MHA-Manager ~]$ vi .bash_profile
...相关配置文件...
PATH=$PATH:/usr/local/mysql/bin
...相关配置文件...
[mysql@MHA-Manager ~]$ source .bash_profile
[mysql@MHA-Manager ~]$ echo $PATH
[mysql@MHA-Manager ~]$ mysql
