摘要：SUSE Linux 11 SP3 64 位操作系统、MySQL5.7.22 二进制安装包、单实例
注：linuxidc 是我的主机名
一、环境准备
操作系统：SuSE 版本 11sp3，64 位
linuxidc:~ # uname -a
Linux linuxidc 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
linuxidc:~ # cat /etc/SuSE-release
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 3
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：
linuxidc:~ # 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、安装过程
1、创建群组及用户
linuxidc:~ # groupadd mysql
linuxidc:~ # useradd -g mysql mysql
2、创建相关目录
linuxidc:~ # 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
linuxidc:~ # chown -R mysql.mysql /data/mysql
3、解压文件，并修改解压后的文件夹的名称
linuxidc:~ # tar -xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
linuxidc:~ # mv mysql-5.7.22-linux-glibc2.12-x86_64 mysql-5.7.22
4、配置环境变量
linuxidc:~ # echo ‘PATH=/root/mysql-5.7.22/bin:$PATH’ >> /etc/profile
linuxidc:~ # source /etc/profile
5、初始化数据库
linuxidc:~ # mysqld –initialize –basedir=/root/mysql-5.7.22 –datadir=/data/mysql/data –user=mysql

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

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

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

# 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
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=<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
#log-bin=mysql-bin
# Uncomment the following if you are using InnoDB tables

六、启动 MySQL 服务
linuxidc:~ # 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
linuxidc:~ # 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
linuxidc:~ # 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
linuxidc:~ # 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。
