1、将安装包MySQL-server-5.5.35-1.linux2.6.x86_64通过ssh工具上传到虚拟机中。
2、使用命令rpm -ivh MySQL-server-5.5.35-1.linux2.6.x86_64.rpm安装
过程中出现问题1：
file /usr/share/mysql/binary-configure from install of MySQL-server-5.5.35-1.linux2.6.x86_64 conflicts with file from package MySQL-server-5.5.59-1.el7.x86_64
解决方法1：
yum -y remove MySQL-server-5.5.59-1.el7.x86_64
重新执行 rpm -ivh MySQL-server-5.5.35-1.linux2.6.x86_64.rpm
过程中出现问题2：
Starting MySQL.................................................................................................
D file (/var/lib/mysql/localhost.localdomain.pid). [失败]
解决方法2：
使用命令vi /var/lib/mysql/localhost.localdomain.err，发现如下错误
InnoDB: Unable to lock ./ibdata1, error: 11
InnoDB: Check that you do not already have another mysqld process
可能是ibddata已经有人读取了，无法取得其权限，不能再次启动，通过命令ps aux|grep mysq* 查看当前运行mysql进程
root 29395 0.0 4.3 422424 43260 ? Sl Sep27 0:15 mysqld --user=root
root 53027 0.0 0.0 103344 860 pts/2 S+ 09:47 0:00 grep mysql
使用命令kill 29395，杀掉进程
3、使用命令service mysql restart 重新启动mysql，启动成功
4、使用命令show variables like 'character%'，查看并修改数据库编码方式
mysql> show variables like 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
需要在my.cnf中修改mysql数据库编码方式
过程中出现问题3：
/etc/下没有my.cnf
解决方法3：
cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
vi /etc/my.cnf
在[client]下添加default_character_set=utf8，
在[mysqld]下添加collation_server = utf8_general_ci
character_set_server = utf8
重新启动mysql，service mysql restart
mysql> show variables like 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
5、修改mysql数据库root用户密码
mysql> use mysql;
Database changed
mysql> update user set password=password('123456') where user='root';
Query OK, 4 rows affected (0.00 sec)
Rows matched: 4 Changed: 4 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> exit
6、对远程访问授权
grant all privileges on *.* to root@'%' identifies by 'xxxxxx';
flush privileges;
其中xxxxx表示root用户的密码
7、导入sql文件
mysql> create database platformhlj;
mysql> source /usr/local/platformhlj.sql;
过程中出现问题4：
[Err] 1418 - This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)
解决方法4：
vi /etc/my.cnf
在my.cnf中添加log_bin_trust_function_creators=1
重启mysql，service mysql restart
mysql> show variables like 'log_bin_trust_function_creators';
+---------------------------------+-------+
| Variable_name | Value |
+---------------------------------+-------+
| log_bin_trust_function_creators | ON |
+---------------------------------+-------+
1 row in set (0.00 sec)
mysql> source /usr/local/platformhlj.sql;
导入成功；
8、将mysql设置为开机自启动（如何在定时器中设置定时检测，这一步可以省略）
将服务文件拷贝到init.d下，命名为mysqld
[root@localhost etc]# cp /usr/share/mysql/mysql.server /etc/init.d/mysqld
赋予可执行权限
[root@localhost etc]# chmod +x /etc/init.d/mysqld
添加服务
[root@localhost etc]# chkconfig --add mysqld
显示服务列表
[root@localhost etc]# chkconfig --list
mysqld 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
重启电脑，查看mysql服务
[root@localhost etc]# reboot
[root@localhost ~]# netstat -apn|grep 3306
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 2182/mysqld
9、在定时器中设置定时检测mysql
在定时器中添加定时执行的脚本crontab -e
*/5 * * * * /usr/local/crondmysql.sh
crondmysql.sh脚本的内容如下所示（网上搜索内容，不是自己写的）：
#!/bin/bash
pgrep -x mysqld &> /dev/null
if [ $? -ne 0 ]
then
echo "At time: `date` :MySQL is stop .">> /usr/local/mysqlstatus.txt
/etc/init.d/mysqld start
else
echo “MySQL server is running .”
