下面将在SUSE Linux 11 64位操作系统中以单实例二进制包方式安装MySQL 5.7.22版本数据库。以下的ywnzlinux是机器的主机名，详细安装步骤如下：

一、环境准备

操作系统是SUSE Linux 11 64位，以下是系统详细信息：

ywnzlinux:~ # uname -a

Linux ywnzlinux 3.0.76-0.11-default #1 SMP Fri Jun 14 08:21:43 UTC 2013 (ccab990) x86_64 x86_64 x86_64 GNU/Linux

ywnzlinux:~ # cat /etc/SuSE-release

SUSE Linux Enterprise Server 11 (x86_64)

VERSION = 11

PATCHLEVEL = 3

二、依赖包

安装依赖软件包：

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：

ywnzlinux:~ # ln -s /usr/lib64/libncurses.so /usr/lib64/libtinfo.so.5

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MySQL 5.7.22具体过程

1、创建群组及用户

ywnzlinux:~ # groupadd mysql

ywnzlinux:~ # useradd -g mysql mysql

2、创建相关目录

ywnzlinux:~ # mkdir -p /data/mysql/{data,tmp}      #创建存放数据文件目录，data与tmp之间不能为空格

ywnzlinux:~ # chown -R mysql.mysql /data/mysql

3、解压文件，并修改解压后的文件夹的名称

ywnzlinux:~ # tar -xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

ywnzlinux:~ # mv mysql-5.7.22-linux-glibc2.12-x86_64 mysql-5.7.22

4、配置环境变量

ywnzlinux:~ # echo 'PATH=/root/mysql-5.7.22/bin:$PATH' >> /etc/profile

ywnzlinux:~ # source /etc/profile

5、初始化数据库

ywnzlinux:~ # mysqld --initialize --basedir=/root/mysql-5.7.22 --datadir=/data/mysql/data --user=mysql

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

socket = /data/mysql/mysql.sock

default-character-set=utf8

# Here follows entries for some specific programs

# The MySQL server

[mysqld]

port = 3306

datadir = /data/mysql/data

tmpdir = /data/mysql/tmp

socket = /data/mysql/mysql.sock

character-set-server = utf8

collation-server = utf8_general_ci

pid-file = /data/mysql/mysql.pid

user = mysql

explicit_defaults_for_timestamp

lower_case_table_names = 1

max_connections = 1000

back_log = 1024

open_files_limit = 10240

table_open_cache = 5120

#bind-address = 127.0.0.1

#skip-name-resolve

skip-external-locking

local-infile = 1

key_buffer_size = 32M

max_allowed_packet = 1M

table_open_cache = 64

sort_buffer_size = 512K

net_buffer_length = 8K

read_buffer_size = 256K

read_rnd_buffer_size = 512K

myisam_sort_buffer_size = 8M

# 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!

#

#skip-networking

# Replication Master Server (default)

# binary logging is required for replication

log-bin = /data/mysql/mysql-bin

# binary logging format - mixed recommended

binlog_format = mixed

# required unique id between 1 and 2^32 - 1

# defaults to 1 if master-host is not set

# but will not function as a master if omitted

server-id = 1

# 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=, MASTER_PORT=,

#    MASTER_USER=, MASTER_PASSWORD= ;

#

#    where you replace , , by quoted strings and

#     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    =

#

# The username the slave will use for authentication when connecting

# to the master - required

#master-user    =

#

# The password the slave will authenticate with when connecting to

# the master - required

#master-password =

#

# The port the master is listening on.

# optional - defaults to 3306

#master-port    =

#

# binary logging - not required for slaves, but recommended

#log-bin=mysql-bin

# Uncomment the following if you are using InnoDB tables

#innodb_data_home_dir = /var/lib/mysql

innodb_data_file_path = ibdata1:10M:autoextend

#innodb_log_group_home_dir = /var/lib/mysql

# You can set .._buffer_pool_size up to 50 - 80 %

# of RAM but beware of setting memory usage too high

innodb_buffer_pool_size = 256M

#innodb_additional_mem_pool_size = 2M

# Set .._log_file_size to 25 % of buffer pool size

#innodb_log_file_size = 5M

#innodb_log_buffer_size = 8M

#innodb_flush_log_at_trx_commit = 1

#innodb_lock_wait_timeout = 50

innodb_buffer_pool_instances = 2

innodb_read_io_threads = 8

innodb_write_io_threads = 8

innodb_purge_threads = 1

slow_query_log = 1

long_query_time = 10

六、启动MySQL服务

ywnzlinux:~ # mysqld --defaults-file=/data/mysql/my.cnf --user=mysql &

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

ywnzlinux:~ # mysqladmin -u root -p  password 'root123' -S /data/mysql/mysql.sock

Enter password:

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

ywnzlinux:~ # mysql -uroot -p -S /data/mysql/mysql.sock

注：需要指定 -S 参数

九、防火墙允许3306端口

ywnzlinux:~ # 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：

# 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。

注：以上为单实例二进制方式安装MySQL 5.7.22的全部过程，其它的SUSE Linux操作系统都可以做为安装参考，比如使用SUSE Linux Enterprise Server 15。
