mysql二进制升级_MySQL二进制安装，升级，多实例部署
MySQL二進制安裝，升級，多實例部署
目標
理解線上部署考慮的因素
學會編譯安裝以及二進制安裝mysql
學會升級mysql
學會多實例部署mysql數據庫
學會合理部署mysql線上庫
考慮因素：
版本選擇，5.1,5.5還是5.6？
分支選擇，官方社區版？percona server？mariadb?
推薦官方版，簡單易上手
安裝方式，包安裝？二進制包安裝？源碼安裝？
線上推薦二進制包安裝
路徑配置，參數配置(盡量模板化，標準化)
一個實例多個庫，or多個實例單個庫？
二進制安裝mysql
下載軟件安裝包
解壓放到指定目錄(比如/usr/local)并將mysql目錄放到PATH中
初始化實例，編輯配置文件 并啟動
賬號安全設置
1)下載
2)解壓到指定目錄，并將mysql目錄放到PATH中
#tar -zxf mysql-5.5.50-linux2.6-i686.tar.gz
#mv mysql-5.5.50-linux2.6-i686 /usr/local/#cd/usr/local
#mv mysql-5.5.50-linux2.6-i686 mysql55
#cd mysql55/bin
#export PATH=/usr/local/mysql55/bin:$PATH
3)初始化實例 使用腳本mysql_install_db
#mkdir -p /tmp/mysqldata/node1
#/usr/local/mysql55/script/mysql_install_db --user=mysql --basedir=/usr/local/mysql55 --datadir=/tmp/mysqldata/node1
#cd/tmp/mysqldata/node1
出現問題1 沒有libaio.so.1庫
/tmp/mysql55/bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解決：查詢libaio庫并按照libaio.so.1
查詢
linuxidc@linuxidc:/tmp$ sudo apt-cache search libaio
libaio-dev - Linux kernel AIO access library -development files
libaio1- Linux kernel AIO access library -shared library
libaio1-dbg - Linux kernel AIO access library - debugging symbols
安裝
linuxidc@linuxidc:/tmp$ sudo apt-get install libaio1

拷貝配置文件：support-files中拷貝my-medium.cnf
cp /usr/local/mysql56/support-files/my-medium.cnf /tmp/mysqldata
3)使用mysqld_safe腳本，啟動
/usr/local/mysql55/bin/mysqld_safe --defaults-file=/tmp/mysqldata/my.cnf &

疑問：
不知是Ubuntu指定了basedir=/usr/local/mysql,datadir=/usr/local/mysql/data;還是最開始的初始化沒有管用，還是有什么配置沒有寫在配置文件中。
當然是沒有寫在配置文件中了，可以查看一下my-medium.cnf內容
[client]

# Here follows entriesforsome specific programs
# The MySQL server

沒有相關目錄的配置；
在my.cnf 增加一下配置

mysql升級
從5.5升級到5.6
下載mysql5.6安裝包并配置mysql5.6安裝包安裝路徑
關閉mysql5.5的實例，修改部分參數，使用mysql5.6軟件啟動
執行mysql5.6路徑下mysql_upgrade腳本
驗證是否成功升級
MySQL升級
1)關閉mysql

mysql多實例安裝
部署好mysql軟件
編輯多個配置文件，初始化多個實例
啟動mysql實例
為啥多實例部署？
充分利用系統資源
資源隔離
業務，模塊隔離
多實例安裝
#mkdir -p /mysqldata/node3
a) 初始化實例 使用腳本mysql_install_db
linuxidc@linuxidc:/tmp/mysqldata/node1$ /usr/local/mysql56/scripts/mysql_install_db --user=linuxidc --basedir=/usr/local/mysql56 --datadir=/tmp/mysqldata/node3
#查看
linuxidc@linuxidc:/tmp/mysqldata/node1$ ls ../node3

b) 給node3配置文件
cpmy2.cnf my3.cnf
vim my3.cnf(修改相關參數)

log-error = /tmp/mysqldata/node3/linuxidc.log
log-bin = /tmp/mysqldata/node3/mysql-bin.log
c) 使用mysqld_safe,及my3.cnf拉起實例

可以看到有兩個端口的mysqld，分別是3306,3308；
e) 登陸新實例，刪除test庫，空用戶，設置root密碼
