一、关闭防火墙

chkconfig iptables off

service iptables stop

二、检查操作系统上是否安装了MySQL

[[email protected] backup]# rpm -qa |grep mysql

qt-mysql-4.6.2-26.el6_4.x86_64

mysql-5.1.71-1.el6.x86_64

mysql-server-5.1.71-1.el6.x86_64

mysql-devel-5.1.71-1.el6.x86_64

mysql-libs-5.1.71-1.el6.x86_64

三、删除MyQL(redhat6.3服务器自带的mysql-libs是mysql-libs-5.1.61-4.el6.x86_64，可能会和高版本的mysql-libs有冲突)

yum remove mysql-libs

四、确定MySQL相关包彻底删除

[[email protected] backup]# rpm -qa |grep mysql

五、下载mysql源码包，mysql-5.6.23.tar.gz

下载时注意别选成其他的linux安装包，不然编译肯定报错。选择平台的下拉列表里选择 Source Code，Select Platform: Source Code ，

下载 Generic Linux (Architecture Independent), Compressed TAR Archive。

六、添加用户和组:groupadd mysql #增加用户组

useradd -d /home/mysql -g mysql mysql

七、配MySQL环境变量

su - mysql

vi .bash_profile

PATH=$PATH:$HOME/bin:/u01/my3306/bin

source .bash_profile

八、创建目录及授权

mkdir -p /u01/my3306/data

mkdir -p /u01/my3306/log/iblog

mkdir -p /u01/my3306/log/binlog

mkdir -p /u01/my3306/log/relaylog

mkdir -p /u01/my3306/run

mkdir -p /u01/my3306/tmp

chown -R mysql:mysql /u01/my3306

chmod -R 777 /u01/my3306

九、解压

tar -zxvf mysql-5.6.23.tar.gz

cd mysql-5.6.23

十、编译并安装

cmake -DCMAKE_INSTALL_PREFIX=/u01/my3306 -DINSTALL_DATADIR=/u01/my3306/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DWITH_SSL=yes -DWITH_EMBEDDED_SERVER=1 -DENABLED_LOCAL_INFILE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DMYSQL_UNIX_ADDR=/u01/my3306/run/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DSYSCONFDIR=/etc -DWITH_READLINE=on

make

make install

十一、参数配置/u01/my3306/my.cnf

[client]

pid_file=/u01/my3306/run/mysqld.pid

[mysqld_safe]

datadir=/u01/my3306/data

十二、初始化MySQL脚本

rm -rf /u01/my3306/data/*

rm -rf /u01/my3306/log/iblog/*

rm -rf /u01/my3306/log/binlog/*

chmod -R 777 /u01/my3306/data/

chmod -R 777 /u01/my3306/log/iblog/

chmod -R 777 /u01/my3306/log/binlog/

chmod 755 /u01/my3306/my.cnf

./scripts/mysql_install_db --defaults-file=/u01/my3306/my.cnf --datadir=/u01/my3306/data --user=mysql

chmod -R 777 /u01/my3306/data/

chmod -R 777 /u01/my3306/log/iblog/

chmod -R 777 /u01/my3306/log/binlog/说明:defaults-file表示指定默认的配置文件，如果不指定，系统默认的优先级是先使用/etc/my.cnf作为mysql的配置文件，那之前make的那些参数就白设置了.

在初化时进行日志监控tail -f /u01/my3306/log/alert.log

**************************************************************************************************************

报错处理：

RSA private key file not found: /u01/my3306/data//private_key.pem. Some authentication plugins will not work.

RSA public key file not found: /u01/my3306/data//public_key.pem. Some authentication plugins will not work.

解决方法如下：

1. 检查是否安装openssl

$rpm -qa openssl

openssl-1.0.0-20.el6_2.5.x86_64

2.利用openssl生成公有和私有key

$ openssl genrsa -out mykey.pem 1024

Generating RSA private key, 1024 bit long modulus

..........++++++

.++++++

e is 65537 (0x10001)

$ openssl rsa -in mykey.pem -pubout -out mykey.pub

writing RSA key

$ ll mykey*

[[email protected] my3306]# ll mykey*

-rw-r--r-- 1 root root 891 Apr  1 20:35 mykey.pem

-rw-r--r-- 1 root root 272 Apr  1 20:35 mykey.pub

3.修改key的权限

chmod 755 /u01/my3306/mykey.pem

chmod 755 /u01/my3306/mykey.pub

$ ll mykey*

[[email protected] my3306]# ll mykey*

-rwxr-xr-x 1 root root 891 Apr  1 20:35 mykey.pem

-rwxr-xr-x 1 root root 272 Apr  1 20:35 mykey.pub

4、添加参数到[mysqld]中即： vi my.cnf

[mysqld]

sha256_password_private_key_path=/u01/my3306/mykey.pem

sha256_password_public_key_path=/u01/my3306/mykey.pub

**********************************************************************************************

十三、启动mysqlvi .bash_profile ---root用户下添加

PATH=$PATH:$HOME/bin:/u01/my3306/bin

mysqld_safe --defaults-file=/u01/my3306/my.cnf --user=mysql &

十四、登录MySQL

[[email protected] ~]# mysql -h127.0.0.1 -uroot
