CentOS 7使用通过二进制包安装MySQL 5.7.18

安装依赖

yum install -y libaio

下载

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz -O mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz

创建目录

mkdir -p /data/service/mysql

解压

tar zxvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.18-linux-glibc2.5-x86_64/* /data/service/mysql

创建用户组

groupadd mysql
useradd -g mysql -s /sbin/nologin mysql

修改权限

chown -R mysql:mysql /data/service/mysql

配置环境变量

cat <<EOF > /etc/profile.d/mysql.sh
export PATH=/data/service/mysql/bin:$PATH
EOF

. /etc/profile

目录规划（由于mysql特殊，必须使用在/usr/local/mysql的路径才行，那么采取的方法是软链接，不建议直接安装到/usr/local/mysql的路径，迁移是个很麻烦的问题）

# 数据datadir /usr/local/mysql/data   
# 参数文件my.cnf    /usr/local/mysql/etc/my.cnf 
# 错误日志log-error /usr/local/mysql/log/mysql_error.log    
# 二进制日志log-bin  /usr/local/mysql/binlogs/mysql-bin
# 慢查询日志slow_query_log_file  /usr/local/mysql/log/mysql_slow_query.log   
# 套接字socket文件   /usr/local/mysql/run/mysql.sock 
# pid文件 /usr/local/mysql/run/mysql.pid

mkdir -p /data/service/mysql/{binlogs,log,etc,run}
mkdir -p /data/database
ln -s /data/service/mysql /usr/local/mysql
ln -s /data/database /usr/local/mysql/data
chown -R mysql.mysql /data/service/mysql/
chown -R mysql.mysql /usr/local/mysql/{data,binlogs,log,etc,run}

设置配置文件

rm -rf /etc/my.cnf #原文件是mariadb客户端留下的，不需要使用

cat <<EOF > /usr/local/mysql/etc/my.cnf

socket = /usr/local/mysql/run/mysql.sock

query_cache_size = 0

server-id=1
EOF

初始化

mysqld --initialize --user=mysql --datadir=/data/database --basedir=/data/service/mysql
# 此时会输出临时密码，一定要记住
echo "请记住这个临时root密码！！！"

生成ssl

mysql_ssl_rsa_setup --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/

设置启动项目

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql.server
chkconfig --add mysql.server
chkconfig mysql.server on

启动

service mysql.server start

重置root密码，此时关闭

mysql_secure_installation

类似以下信息：

Securing the MySQL server deployment.

Enter password for user root: 

The existing password for the user account root has expired. Please set a new password.

New password: 

Re-enter new password: 

VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No: Y

There are three levels of password validation policy:

LOW    Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2
Using existing password for root.

Estimated strength of the password: 100 
Change the password for root ? ((Press y|Y for Yes, any other key for No) : N

 ... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y
Success.


Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y
Success.

By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.


Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y
Success.

All done!

目的是：

• 重置密码
• 删除匿名用户
• 关闭root用户的远程登录
• 删除测试数据库
