二进制免安装方式，配置mysql

mysql 5.7.22版本二进制包安装方法

环境标准化采样：

检查系统内是否有其他mysql
rpm -qa | grep mysql

是否存在mysql用户和用户组
grep mysql /etc/group

查看linux系统版本
[root@fp-web-112 src]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
内存基本页大小
[root@fp-web-112 src]# getconf PAGE_SIZE
4096 //4m
//内核版本
[root@fp-web-112 src]# uname -a

查看linux是32位还是64位（下载包的时候要注意）
[root@fp-web-112 src]# getconf LONG_BIT
64

查看系统负载磁盘和分区
[root@fp-web-112 src]# cat /proc/loadavg

查看挂载情况(以后可能会面临磁盘空间问题)

简单准备：

netstat -s
netstat -lntp                      # 查看所有监听端口
netstat -lntup | grep 3306         #mysql端口
ps -ef | grep mysqld               #进程端口
tcpdump -i ens192 -s 0 -l -w - dst port 3306 | strings | perl -e #抓包
netstat -anp | grep 3306 | wc -l   #当前 Mysql连接数

一、目录规划：

程序目录：/usr/local/mysql
数据目录：/data/mysql
PID和SOCKET文件位置：/tmp

二、文件下载：
官方默认只提供最新版本的，历史版本的下载地址：
https://downloads.mysql.com/archives/

5.7.22版本下载：

[root@fp-web-112 var]# wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
[root@fp-web-112 var]#  md5sum mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
[root@fp-web-112 var]# tar -xzf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
[root@fp-web-112 var]# mv /usr/local/mysql-5.7.22-linux-glibc2.12-x86_64/ /usr/local/mysql
[root@fp-web-112 var]# echo "export PATH=$PATH:/usr/local/mysql/bin" >/etc/profile.d/mysql.sh
[root@fp-web-112 var]# source /etc/profile.d/mysql.sh

三、创建用户和授权：

注：-g：指定新用户所属的用户组(group)； -M：不建立根目录；-s：定义其使用的shell,/sbin/nologin代表用户不能登录系统。
useradd -u 用户id -g 组id/组名用户名

[root@fp-web-112 var]#groupadd mysql //创建mysql组
groupadd -g 27 mysql
[root@fp-web-112 var]#useradd mysql //创建mysql用户
useradd -g mysql -s /bin/false mysql
useradd mysql -g mysql -M -s /sbin/nologin
[root@fp-web-112 var]#passwd mysql
[root@fp-web-112 var]#mkdir -p /data/mysql
[root@fp-web-112 var]#chown -R mysql:mysql /data/mysql
[root@fp-web-112 var]#chmod -R 755 /data/mysql

四、设置参数：my.cnf

[mysqld]
#basic
#skip-grant-tables
#validate_password =OFF
datadir = /data/mysql
port = 3306
pid-file = /tmp/mysql.pid
socket = /tmp/mysql.sock

slow-query-log = 1
slow-query-log-file = slow.log
long_query_time = 0.2
log-bin = mysql_bin.log
binlog_format = ROW
expire-logs-days = 1
relay-log = mysql_relay.log
relay_log_recovery = 1
general_log = on
general_log_file = general.log
lower_case_table_names = 1

character_set_client_handshake = FALSE
character_set_server = utf8mb4

interactive_timeout = 172800

max_prepared_stmt_count =1048576
max_connections = 8000

innodb_stats_persistent = 1
#innodb_spin_wait_delay= 6 / 96

innodb_adaptive_hash_index=0

innodb_monitor_enable = '%'

[mysql]
user = root

五、初始化数据库实例，安装mysql权限表，解压之后你最好对比data目录不同，这样你会更深刻，一旦初始化会生成很多文件。

/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql --initialize-insecure

六、启动：

# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
# /etc/init.d/mysql start
Starting MySQL... SUCCESS!

七、验证和设置远程访问：

[root@node1 soft]# mysql -p -S /tmp/mysql.sock
mysql> grant all privileges on *.* to root@'%' identified by 'jinzs' with grant option;
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
