检查mysql组和用户是否存在，如无创建
groupadd mysql // 建一个msyql的用户和组
useradd -g mysql mysql
mkdir /usr/local/mysql // 创建目录
mkdir /usr/local/mysql/data // 数据仓库目录
chown -R mysql ./mysql

配置环境变量
export PATH=/usr/local/mysql/bin:$PATH
然后立马生效，执行
source /etc/profile
cp -a ./support-files/mysql.server /etc/init.d/mysqld
初始化
./bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize --console
报错： error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
yum install -y libaio
./bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize --console
启动mysqld服务
service mysqld start
/bin/systemctl start mysqld.service
如果失败，删除
/tmp/mysql.sock
/tmp/mysql.sock.lock
原密码：
g24?(42r2Ss3
g:k(4)I8Jt6/
iQg8grqsDy+%
修改密码
ALTER USER 'root'@'localhost' IDENTIFIED BY '*Lin424802!';
ALTER USER 'root'@'localhost' IDENTIFIED BY 'Xiaozhangbang2019';
set password = password('*Lin424802!');
添加远程连接权限
use mysql;
update user set host="%" where user='root';
原因显示：host+user 应该是联合主键，冲突了
select user,host from user;
update user set host = '%' where user = 'root' and host='localhost';
GRANT ALL ON *.* TO 'root'@'%';
flush privileges;

记录linux每个用户操作日志
通过在/etc/profile里面加入以下代码就可以实现：
PS1="`whoami`@`hostname`:"'[$PWD]'
history
USER_IP=`who -u am i 2>/dev/null| awk '{print $NF}'|sed -e 's/[()]//g'`
if [ "$USER_IP" = "" ]
then
USER_IP=`hostname`
fi
if [ ! -d /tmp/history ]
then
mkdir /tmp/history
chmod 777 /tmp/history
fi
if [ ! -d /tmp/history/${LOGNAME} ]
then
mkdir /tmp/history/${LOGNAME}
chmod 300 /tmp/history/${LOGNAME}
fi
export HISTSIZE=4096
DT=`date +"%Y%m%d_%H%M%S"`
export HISTFILE="/tmp/history/${LOGNAME}/${USER_IP} history.$DT"
chmod 600 /tmp/history/${LOGNAME}/*history* 2>/dev/null
