摘要：SuSE11sp3 64位操作系统、MySQL5.7.22 rpm安装包
5.7版本与先前版本安装有所区别，需要注意
注：kingtry是我的主机名
一、环境准备
操作系统：SuSE版本11sp3，64位kingtry:~#uname-a
Linuxkingtry3.0.76-0.11-default#1SMPFriJun1408:21:43UTC(ccab990)x86_64x86_64x86_64GNU/Linux
kingtry:~#cat/etc/SuSE-release
SUSELinuxEnterpriseServer11(x86_64)
VERSION=11
PATCHLEVEL=3
二、检测是否安装过MySQL
我的电脑上显示以前安装过5.1.73版本的mysql，这个显示信息与实际情况相关。kingtry:~#rpm-qa|grep-imysql
libmysqlclient_r15-5.0.96-0.6.1
libqt4-sql-mysql-4.6.3-5.25.4
MySQL-client-community-5.1.73-1.sles11
MySQL-server-community-5.1.73-1.sles11
注意输出的MySQL-*，表示已经安装过。lib开头的可以忽略。
输入以下命令删除：kingtry:~#rpm-eMySQL-client-community-5.1.73-1.sles11
kingtry:~#rpm-eMySQL-server-community-5.1.73-1.sles11
三、软件准备mysql-community-common-5.7.22-1.sles11.x86_64.rpm
mysql-community-libs-5.7.22-1.sles11.x86_64.rpm
mysql-community-client-5.7.22-1.sles11.x86_64.rpm
mysql-community-server-5.7.22-1.sles11.x86_64.rpm
四、安装软件
注：4个rpm安装包，有依赖关系，按照以下顺序分别安装即可。kingtry:~#rpm-ivhmysql-community-common-5.7.22-1.sles11.x86_64.rpm
kingtry:~#rpm-ivhmysql-community-libs-5.7.22-1.sles11.x86_64.rpm
kingtry:~#rpm-ivhmysql-community-client-5.7.22-1.sles11.x86_64.rpm
kingtry:~#rpm-ivhmysql-community-server-5.7.22-1.sles11.x86_64.rpm
五、修改配置文件/etc/f
软件安装之后自动生成/etc/f文件，实际生成文件内容比较简单，下面是我修改之后的

六、初始化数据库
注：5.7版本的rpm包安装之后默认不再创建数据库，mysql服务也不会自动启动。但是它还是自动增加了系统用户mysql。kingtry:~#mkdir-p/data/mysql/data#创建存放数据文件目录
kingtry:~#chown-Rmysql/data/mysql
kingtry:~#mysqld--initialize--datadir=/data/mysql/data/--user=mysql#初始化
初始化成功之后，会将root的默认密码写入文件：/data/mysql/mysql.err中，如下：Atemporarypasswordisgeneratedfor[emailprotected]:_tVUgaq%P25Q#这就是root的默认密码
七、启动mysql服务即可kingtry:~#servicemysqlstartdone
StartingMySQL.done
kingtry:~#
检查MySQL服务是否已经启动：kingtry:~#netstat-nat|grep3306
八、安装后配置之root密码修改
root初始密码自动生成，默认存放在/data/mysql/mysql.err中。修改root密码的方式有以下两种，随便哪个都行：
1、命令方式kingtry:~#mysqladmin-uroot-ppassword'root123'
Enterpassword:
2、修改库表数据方式
先登陆mysql服务器mysql>usemysql
mysql>updateusersetpassword=password('root123')whereuser='root';
mysql>commit;
九、防火墙允许3306端口kingtry:~#vi/etc/sysconfig/SuSEfirewall2
在FW_SERVICES_EXT_TCP增加3306端口，如果存在其他端口，则空格隔开，如：
FW_SERVICES_EXT_TCP="21 22 3306"
重启防火墙：#rcSuSEfirewall2restart
十、设置远程访问
先登陆mysql服务器，授权root用户可以远程登陆mysql>grantallPRIVILEGESon*.*to[emailprotected]'%'identifiedby'root123';
QueryOK,0rowsaffected(0.00sec)
mysql>flushprivileges;
QueryOK,0rowsaffected(0.00sec)
mysql>
注：生产环境最好只允许root在特定IP的机器上才能远程访问。
