一、环境准备
操作系统：SuSE版本11sp3，64位
二、依赖包
tack-5.6-90.55.x86_64.rpm
ncurses-devel-5.6-90.55.x86_64.rpm
安装好上面两个依赖包之后，创建连接文件：
注：如果上面连接文件没有创建，则客户端连接mysql服务的时候会报如下异常信息：
error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory
三、软件准备
mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
四、安装过程
1、创建群组及用户
2、创建相关目录
3、解压文件，并修改解压后的文件夹的名称
4、配置环境变量
5、初始化数据库
注：最后一行显示生成的root用户的默认密码
五、创建配置文件/data/mysql/my.cnf
该版本默认没有配置文件的模板，需要手工创建
my.cnf内容参考如下：
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
[client]
#password = your_password
port = 3306

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
log-bin = /data/mysql/mysql-bin
# binary logging format - mixed recommended

# defaults to 1 if master-host is not set
# but will not function as a master if omitted

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>
#
# binary logging - not required for slaves, but recommended

六、启动MySQL服务
七、安装后配置之root密码修改
修改root密码的方式有以下两种，随便哪个都行：
1、shell命令方式
2、mysql命令方式
先登陆mysql服务器
mysql> set password=password('root123')
八、客户端连接MySQL服务
注：需要指定 -S 参数
九、防火墙允许3306端口
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：
# rcSuSEfirewall2 restart
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> grant all PRIVILEGES on *.* to root@'%' identified by 'root123';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
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。
