rpm -qa | grep MysqL
rpm -e --nodeps MysqL*

2、添加MysqL用户和用户组

groupadd MysqL # 创建MysqL组(MysqL运行于特定的组和用户下)
useradd -r -g MysqL MysqL

3、安装依赖

yum install libaio -y # 异步IO库
yum install numactl -y

4、安装MysqL文件到/user/local/MysqL目录下

cd /tmp/
wget https://cdn.mysql.com//Downloads/MySQL-5.6/mysql-5.6.41-linux-glibc2.12-x86_64.tar.gz
#MD5校验
tar zxf mysql-5.6.41-linux-glibc2.12-x86_64.tar.gz # 解压@H_123_20@mv mysql-5.6.41-linux-glibc2.12-x86_64 /usr/local/MysqL

5、修改权限

cd /usr/local/MysqL
chown -R MysqL .
chgrp -R MysqL .

6、初始化数据库

cd /usr/local/MysqL
scripts/MysqL_install_db --user=MysqL #初始化数据库
chown -R root .

主配置文件服务器参数设置

cd /usr/local/MysqL
cp support-files/my-default.cnf /etc/my.cnf
vi /etc/my.cnf

[MysqLd]
basedir=/usr/local/MysqL
datadir=/usr/local/MysqL/data

socket=/usr/local/MysqL/MysqL.sock
user=MysqL

Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0
#default-character-set = utf8

character_set_server = utf8

[MysqLd_safe]
log-error=/var/log/MysqLd.log
pid-file=/var/run/MysqLd/MysqLd.pid
socket=/usr/local/MysqL/MysqL.sock

修改datadir等服务器参数有默认值 默认值为/usr/local/MysqL/data

配置文件的@L_607_53@顺序

为MysqL提供服务脚本

cd /usr/local/MysqL
cp support-files/MysqL.server /etc/rc.d/init.d/MysqLd
MysqLd_safe

开机自启动

chkconfig --add MysqLd
chkconfig MysqLd on

开启MysqL实例

service MysqLd start

修改密码

@R_673_9531@e MysqL.user set password = passworD(‘qiuyue‘) where user = ‘root‘;
FLUSH PRIVILEGES;

添加到系统环境变量

PATH=$PATH:/usr/local/MysqL/bin
MysqLd -V
MysqL -V
MysqLdump -V
