徒手安装mysql 5.7过程

清理MYSQL

rpm -qa|grep mysql
rpm -e mysql-5.1.73-8.el6_8.x86_64

chkconfig --list | grep -i mysql

清除MYSQL包

whereis mysql
rm -rf /usr/lib/mysql

完成目录

Mysql目录安装位置：/usr/local/mysql

数据库保存位置：/usr/local/mysql/data

日志文件： /usr/local/mysql/logs

cd /usr/local
mkdir mysql
cd mysql
mkdir data
mkdir logs

下载文件到 /usr/local 下mysql-5.7.13-linux-glibc2.5-x86_64.tar.gz

解压

tar -xzvf  mysql-5.7.13-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.13-linux-glibc2.5-x86_64/* /usr/local/mysql

用户组 用户

groupadd mysql
useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql

修改权限

创建三个文件

cd /usr/local/mysql/logs
vi error.log
vi mysql.log

cd /usr/local/mysql
chown -R mysql:mysql ./

初始化

bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

临时密码: 2ZpjiHuR)7+T

配置MySQL

cd support-files/
cp /usr/local/mysql/support-files/mysql.server  /etc/init.d/mysqld

修改配置

vim /etc/init.d/mysqld

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

bin/mysqld_safe --user=mysql &
//或者
service mysqld start

编辑my.cnf文件内容

[mysqld]
#datadir=/var/lib/mysql
#socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd
