MySQL rpm 安装

[root@hadoop001 ~]# rpm -e mysql-libs-5.1.73-8.el6_8.x86_64   删除原有的里屋包
[root@hadoop001 ~]# rpm -e --nodeps mysql-libs-5.1.73-8.el6_8.x86_64   有依赖关系，加上--nodeps

[root@hadoop001 ~]# yum search mysql    搜索
[root@hadoop001 ~]# yum install mysql-server.x86_64 mysql.x86_64   安装
[root@hadoop001 ~]# service mysqld start   启动
Starting mysqld:                                           [  OK  ]
[root@hadoop001 ~]# mysql   进入

出现这种报错的解决方案

MySQL tar安装

1.Upload tar

2.Check isnot install 查看别人是否部署

[root@hadoop001 local]# ps -ef|grep mysald   是否有残留进程
root     32382 30576  0 16:15 pts/0    00:00:00 grep mysald

3tar and mv and 软连接

tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz   解压
[root@hadoop001 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql        软连接不需要重命名

4.Create group and user

[root@hadoop001 local]# groupadd -g 101 dba
 [root@hadoop001 local]# useradd -u 521 -g dba -G root -d /usr/local/mysql mysqladmin
 [root@hadoop001 local]# id mysqladmin
uid=521(mysqladmin) gid=101(dba) groups=101(dba),0(root)    

生产上是可切到 su - mysqladmin 的账户

[root@hadoop001 local]# passwd mysqladmin  设置密码
Changing password for user mysqladmin.
New password: 
BAD PASSWORD: it is too simplistic/systematic
BAD PASSWORD: is too simple
Retype new password: 
BAD PASSWORD: it is too simplistic/systematic
BAD PASSWORD: is too simple
Retype new password: 
passwd: all authentication tokens updated successfully.

##未做，但需知道此种方法

## if user mysqladmin is existing,please execute the following command of usermod.
##[root@sht-sgmhadoopnn-01 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin #

[root@hadoop001 local]# su - mysqladmin
-bash-4.1$ 
-bash-4.1$    样式丢失
co 环境变量配置文件至mysqladmin用户的home目录中,以下步骤配置个人环境变量
-bash-4.1$ cp /etc/skel/.* ./
cp: omitting directory `/etc/skel/.'
cp: omitting directory `/etc/skel/..'
cp: cannot create regular file `./.bash_logout': Permission denied
cp: cannot create regular file `./.bash_profile': Permission denied
cp: cannot create regular file `./.bashrc': Permission denied   报错权限受限   切到有权限的用户做
-bash-4.1$ 

[root@hadoop001 local]# cp /etc/skel/.* /usr/local/mysql/  进行配置
cp: omitting directory `/etc/skel/.'
cp: omitting directory `/etc/skel/..'
[root@hadoop001 local]# su - mysqladmin
[mysqladmin@hadoop001 ~]$ 

5.Create /etc/my.cnf(640) rw-r-----
##defualt start: /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf

vi my.cnf 先小写d大写G清空 然后配置以下内容

7.Again install
真正命令

[mysqladmin@hadoop001 ~]$ scripts/mysql_install_db  \
 --user=mysqladmin \
 --basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data


To do so, start the server, then issue the following commands
要我们去启动，嗯成功了

8.Configure mysql service and boot auto start

[root@hadoop001 ~]# cd /usr/local/mysql
[root@hadoop001 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql     #将服务文件拷贝到init.d下，并重命名为mysql
[root@hadoop001 mysql]# chmod +x /etc/rc.d/init.d/mysql   #赋予可执行权限
[root@hadoop001 mysql]# chkconfig --del mysql   #删除服务
[root@hadoop001 mysql]# chkconfig --add mysql   #添加服务
[root@hadoop001 mysql]# chkconfig --level 345 mysql on   # 代表开启自启动

[root@hadoop001 mysql]# vi /etc/rc.local

#!/bin/sh
 BOOTSTRAP_CONF=/ucloud_boot/bsi-ihue3o.conf BOOTSTRAP_DIR=/ucloud_boot DISTRO=centos MAJOR=6 MINOR=6 /bin/bash /ucloud_boot/bootstrap.sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

===============================

重新部署

service mysql stop

rm -rf /usr/local/mysql/arch/*
rm -rf /usr/local/mysql/data/*

scripts/mysql_install_db  \
--user=mysqladmin \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data 

======================================

部署注意：
1 注意一些命令分别是在那些用户下执行
2 MySQL端口号是：3306
3遇到问题找log日志找error关键词
4MySQL文件夹下所有的用户用户组及其本目录的权限变更
