MySQL 5.7 二進位制包部署多例項
目 錄
1.1 前期規劃
01：虛擬機器一臺,2vCPU,4G記憶體,分別部署3306和3307兩個例項,使用"多配置檔案"的方式
02：MySQL程式的安裝目錄：/data/apps/mysql-5.7.22 要做軟體連結：/data/apps/mysql
03：3306例項的配置檔案路徑為：/data/mysql/3306/my.cnf
04：3307例項的配置檔案路徑為：/data/mysql/3307/my.cnf
05：3306例項的相關目錄：/data/mysql/3306/{data,binlog,slowlog,errlog,redolog }
06：3307例項的相關目錄：/data/mysql/3307/{data,binlog,slowlog,errlog,redolog }
07：採用MySQL通用二進位制包(mysql-5.7.22-linux-glibc2.12-x86_64.tar)
1.2 系統環境

1.4 安裝程式
##解除安裝系統自帶的mysql相關程式
[[email protected] ~]# rpm -qa|grep mysql
mysql-libs-5.1.73-7.el6.x86_64
[[email protected] ~]# rpm -e --nodeps mysql-libs-5.1.73-7.el6.x86_64
[[email protected] ~]# rpm -qa|grep mysql
[[email protected] ~]#
##檢查是否有libaio軟體包（如果沒有則用yum install libaio -y命令來安裝，前提是要能上網）
[[email protected] ~]# rpm -qa|grep libaio
libaio-0.3.107-10.el6.x86_64
##建立mysql使用者，不讓其登入，不建立家目錄
[[email protected] ~]# useradd -s /sbin/nologin -M mysql
[[email protected] ~]# id mysql
uid=501(mysql) gid=501(mysql) groups=501(mysql)
[[email protected] ~]# tail -1 /etc/passwd
mysql:x:501:501::/home/mysql:/sbin/nologin
##建立/data/apps目錄和/root/tools目錄,上傳軟體到/root/tools後，解壓到/data/apps目錄下
[[email protected] ~]# mkdir -p /data/apps /root/tools
[[email protected] ~]# 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/
[[email protected] ~]# cd /root/tools/
[[email protected] tools]# rz
[[email protected] 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
[[email protected] tools]# tar xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /data/apps/
[[email protected] tools]# mv /data/apps/mysql-5.7.22-linux-glibc2.12-x86_64/ /data/apps/mysql-5.7.22
[[email protected] tools]# ln -s /data/apps/mysql-5.7.22/ /data/apps/mysql
[[email protected] tools]# ll /data/apps/mysql
lrwxrwxrwx 1 root root 24 Dec 9 00:09 /data/apps/mysql -> /data/apps/mysql-5.7.22/
[[email protected] tools]# chown -R mysql:mysql /data/apps/mysql/
[[email protected] tools]# ls -ld /data/apps/mysql/
drwxr-xr-x 9 mysql mysql 4096 Dec 9 00:08 /data/apps/mysql/
[[email protected] tools]# echo "PATH=/data/apps/mysql/bin:$PATH" >>/etc/bashrc
[[email protected] tools]# source /etc/bashrc
[[email protected] tools]# echo $PATH
/data/apps/mysql/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
