前文已述，因為需要測試mysql的主從配置方案，所以要安裝多個mysql。這次是在ubuntu kylin 14.10上安裝多個mysql 5.7.14。
系統環境：ubuntu kylin 14.10，64位系統
mysql版本：5.7.14社區版
mysql下載地址：http://dev.mysql.com/downloads/mysql/,選擇 Linux - Generic,下載612.9M的mysql-5.7.14-linux-glibc2.5-x86_64.tar.gz
mysql官方安裝文檔：http://dev.mysql.com/doc/refman/5.7/en/binary-installation.html1.按照官方安裝文檔進行即可，只是一些shell命令做了修改，對ubuntu來說，大部分命令都需要在前面增加sudo
shell> sudo groupadd mysql shell> sudo useradd -r -g mysql -s /bin/false mysql shell> cd /usr/local shell> sudo tar -zxvf /path/to/mysql-VERSION-OS.tar.gz shell> sudo mv mysql-5.7.14-linux-glibc2.5-x86_64 mysql-5.7.14-linux-glibc2.5-x86_64-3306 #將mysql的目錄改了一下名 shell> sudo ln -s mysql-5.7.14-linux-glibc2.5-x86_64-3306 mysql-3306 shell> cd mysql-3306 shell> sudo mkdir mysql-files shell> sudo chmod 750 mysql-files shell> sudo chown -R mysql:mysql . shell> sudo cp support-files/my-default.cnf ./my.cnf #copy一份my.cnf 接著編輯my.cnf,打開basedir，datadir，port等項，按如下配置： basedir = /usr/local/mysql-3306 datadir = /usr/local/mysql-3306/data port = 3306 server_id = 11 然後開始初始化3306端口上的mysql： shell> sudo bin/mysqld --defaults-file=/usr/local/mysql-3306/my.cnf --initialize --user=mysql 2016-07-29T15:38:48.896585Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

Table 'mysql.gtid_executed' cannot be opened. 2016-07-29T15:38:51.090179Z 1 [Note] A temporary password is generated for root@localhost: pJLwjf%q;1t） shell> sudo bin/mysql_ssl_rsa_setup --defaults-file=/usr/local/mysql-3306/my.cnf Generating a 2048 bit RSA private key .........+++ .......................+++ writing new private key to 'ca-key.pem' ----- Generating a 2048 bit RSA private key ..........+++ ..............................................................+++ writing new private key to 'server-key.pem' ----- Generating a 2048 bit RSA private key ................................................+++ ........................................+++ writing new private key to 'client-key.pem' ----- shell> sudo chown -R root . shell> sudo chown -R mysql data mysql-files shell> sudo bin/mysqld_safe --user=mysql & #啟動mysql，在後台運行 # Next command is optional shell> cp support-files/mysql.server /etc/init.d/mysql.server
2.開始登錄mysql進行相關操作
/usr/local/mysql-3306> bin/mysql -uroot -p
注意在執行bin/mysqld初始化時，在命令行最後的提示中給出了一個臨時口令，輸入之後即可登錄。登錄mysql之後，要求立即修改密碼，否則不能進行任何操作。執行下面的命令修改'root'@'localhost'的密碼：
mysql> SET PASSWORD = PASSWORD('your new password');
mysql> ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
mysql> flush privileges;
為了可以遠程登錄，增加一個'root'@'%'賬號：
復制代碼 代碼如下:mysql> grant all privileges on *.* to 'root'@'%' identified by 'your new password' with grant option;
3.按照上面的辦法，繼續解壓安裝mysql-5.7.14-linux-glibc2.5-x86_64.tar.gz，並且配置為3307，3308,3309端口，就可以安裝多個mysql了。
