1.1 前期規劃

01：虛擬機一臺,2vCPU,4G內存,分別部署3306和3307兩個實例,使用"多配置文件"的方式

02：MySQL程序的安裝目錄：/data/apps/mysql-5.7.22 要做軟件鏈接：/data/apps/mysql

03：3306實例的配置文件路徑爲：/data/mysql/3306/my.cnf

04：3307實例的配置文件路徑爲：/data/mysql/3307/my.cnf

05：3306實例的相關目錄：/data/mysql/3306/{data,binlog,slowlog,errlog,redolog }

06：3307實例的相關目錄：/data/mysql/3307/{data,binlog,slowlog,errlog,redolog }

07：採用MySQL通用二進制包(mysql-5.7.22-linux-glibc2.12-x86_64.tar)

1.2 系統環境

1.5 安裝程序

##卸載系統自帶的mysql相關程序

[root@db01 ~]# rpm -qa|grep mysql

mysql-libs-5.1.73-7.el6.x86_64

[root@db01 ~]# rpm -e --nodeps mysql-libs-5.1.73-7.el6.x86_64

[root@db01 ~]# rpm -qa|grep mysql

##安裝相關的依賴包

[root@db01 ~]# yum install gcc gcc-c++ bison ncurses ncurses-devel numactl zlib libxml2 openssl libaio libstdc++-devel -y

[root@db01 ~]# rpm -qa gcc gcc-c++ bison ncurses ncurses-devel numactl zlib libxml2 openssl libaio libstdc++-devel

##創建mysql用戶，不讓其登錄，不創建家目錄

[root@db01 ~]# useradd -s /sbin/nologin -M mysql

[root@db01 ~]# id mysql

uid=501(mysql) gid=501(mysql) groups=501(mysql)

[root@db01 ~]# tail -1 /etc/passwd

mysql:x:501:501::/home/mysql:/sbin/nologin


##創建/data/apps目錄和/root/tools目錄,上傳軟件到/root/tools後，解壓到/data/apps目錄下

[root@db01 ~]# mkdir -p /data/apps /root/tools

[root@db01 ~]# ls -ld /data/apps/ /root/tools/

drwxr-xr-x 2 root root 4096 Dec 8 23:54 /data/apps/

drwxr-xr-x 2 root root 4096 Dec 8 23:54 /root/tools/

[root@db01 ~]# cd /root/tools/

[root@db01 tools]# rz

[root@db01 tools]# ll mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

-rw-r--r-- 1 root root 643790848 Nov 21 09:47 mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

[root@db01 tools]# tar xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /data/apps/

[root@db01 tools]# mv /data/apps/mysql-5.7.22-linux-glibc2.12-x86_64/ /data/apps/mysql-5.7.22

[root@db01 tools]# ln -s /data/apps/mysql-5.7.22/ /data/apps/mysql

[root@db01 tools]# ll /data/apps/mysql

lrwxrwxrwx 1 root root 24 Dec 9 00:09 /data/apps/mysql -> /data/apps/mysql-5.7.22/

[root@db01 tools]# chown -R mysql:mysql /data/apps/mysql/

[root@db01 tools]# ls -ld /data/apps/mysql/

drwxr-xr-x 9 mysql mysql 4096 Dec 9 00:08 /data/apps/mysql/

[root@db01 tools]# echo "PATH=/data/apps/mysql/bin:$PATH" >>/etc/bashrc

[root@db01 tools]# source /etc/bashrc

[root@db01 tools]# echo $PATH

/data/apps/mysql/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

1.6.3 初始化準備並且初始化

##創建錯誤日誌文件

[root@db01 ~]# grep "errlog" /data/mysql/3306/my.cnf

log-error=/data/mysql/3306/errlog/mysql_error.log

[root@db01 ~]# touch /data/mysql/3306/errlog/mysql_error.log

[root@db01 ~]# ll /data/mysql/3306/errlog/mysql_error.log

-rw-r--r-- 1 root root 0 Dec 9 00:29 /data/mysql/3306/errlog/mysql_error.log


##更改/data/mysql/3306/目錄下所有文件的屬主/組爲mysql用戶

[root@db01 ~]# chown -R mysql:mysql /data/mysql/3306/

[root@db01 ~]# ls -ld /data/mysql/3306/

drwxr-xr-x 7 mysql mysql 4096 Dec 9 00:25 /data/mysql/3306/


##初始化3306實例

[root@db01 ~]# mysqld --defaults-file=/data/mysql/3306/my.cnf --user=mysql --basedir=/data/apps/mysql --datadir=/data/mysql/3306/data/ --initialize

[root@db01 ~]# echo $?

0

1.6.4 編寫3306實例的啓動腳本

注意：

01：該腳本中停止mysql的方法爲：

mysqladmin -uUser -pPassword -S /data/mysql/3306/mysql.sock shutdown

02：腳本中有一個Pass變量，就是MySQL root用戶的密碼

03：當然你也可以設置成其它密碼，但必須得改腳本中的Pass變量的值（前提是用這個腳本）

1.6.5 啓動3306實例且修改密碼

##設置/data/mysql/3306/mysqld腳本的權限爲700（因爲腳本中有root用戶的密碼）

[root@db01 ~]# chmod 700 /data/mysql/3306/mysqld

[root@db01 ~]# ll /data/mysql/3306/mysqld

-rwx------ 1 root root 1897 Dec 9 00:44 /data/mysql/3306/mysqld


##啓動3306實例服務

[root@db01 ~]# /data/mysql/3306/mysqld start

Start MySQL [3306] [ OK ]

[root@db01 ~]# netstat -lntup|grep 3306

tcp 0 0 :::3306 :::* LISTEN 3442/mysqld


##修改mysql root的密碼爲chenliang（因爲現在爲初始密碼，必須得先改密碼）

[root@db01 ~]# grep "password" /data/mysql/3306/errlog/mysql_error.log

2018-12-09T00:34:38.917317+08:00 1 [Note] A temporary password is generated for root@localhost: emo*lwNYj2X0

    mysqladmin -uUser -pPassword -S /data/mysql/3307/mysql.sock shutdown

02：腳本中有一個Pass變量，就是MySQL root用戶的密碼

03：當然你也可以設置成其它密碼，但必須得改腳本中的Pass變量的值（前提是用這個腳本）

1.7.5 啓動3307實例且修改密碼

##設置/data/mysql/3307/mysqld腳本的權限爲700（因爲腳本中有root用戶的密碼）

[root@db01 ~]# chmod 700 /data/mysql/3307/mysqld

[root@db01 ~]# ll /data/mysql/3307/mysqld

-rwx------ 1 root root 1897 Dec 9 01:18 /data/mysql/3307/mysqld


##啓動3307實例

[root@db01 ~]# /data/mysql/3307/mysqld start

Start MySQL [3307] [ OK ]

[root@db01 ~]# netstat -lntup|grep 3307

tcp 0 0 :::3307 :::* LISTEN 4709/mysqld


##修改mysql root的密碼爲chenliang（因爲現在爲初始密碼，必須得先改密碼）

[root@db01 ~]# grep "password" /data/mysql/3307/errlog/mysql_error.log

2018-12-09T01:14:15.815156+08:00 1 [Note] A temporary password is generated for root@localhost: >G(pEA)ao5H+

[root@db01 ~]# mysql -uroot -p -S /data/mysql/3307/mysql.sock

Enter password: <==輸入密碼>G(pEA)ao5H+

mysql>

mysql> alter user 'root'@'localhost' identified by 'chenliang';

Query OK, 0 rows affected (0.04 sec)


mysql> select user,host,authentication_string,password_expired from mysql.user where user='root' and host='localhost';

+------+-----------+-------------------------------------------+------------------+

| user | host      | authentication_string                     | password_expired |

+------+-----------+-------------------------------------------+------------------+

| root | localhost | *D072DB593E2E7B068E887A452EB1DB3981A5D844 | N                |

+------+-----------+-------------------------------------------+------------------+

1 row in set (0.00 sec)


mysql> flush privileges;

Query OK, 0 rows affected (0.01 sec)


mysql> exit

Bye

[root@db01 ~]# mysql -uroot -p -S /data/mysql/3307/mysql.sock -e "show databases;"

Enter password:  <==輸入密碼chenliang

+--------------------+

| Database           |

+--------------------+

| information_schema |

| mysql              |

| performance_schema |

| sys                |

+--------------------+

1.7.6 加入開機自啓動

[root@db01 ~]# echo -ne "\n# Boot start mysql service[3307].USER:chenliang TIME:2018-11-23\n/data/mysql/3307/mysqld start\n" >>/etc/rc.local

[root@db01 ~]# tail -2 /etc/rc.local

# Boot start mysql service[3307].USER:chenliang TIME:2018-11-23

/data/mysql/3307/mysqld start

1.8 查看3306和3307實例的運行情況

[root@db01 ~]# netstat -lntup|grep 330*

tcp 0 0 :::3306 :::* LISTEN 3442/mysqld

tcp 0 0 :::3307 :::* LISTEN 4709/mysqld

[root@db01 ~]# netstat -lntup|grep mysql

tcp 0 0 :::3306 :::* LISTEN 3442/mysqld

tcp 0 0 :::3307 :::* LISTEN 4709/mysqld
