啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊啊??????????? 剛剛沒有儲存，得重寫，抓狂×3 終於補完了Linux命令，今天繼續補MySQL??????????? MySQL環境部署，內容很多?????????????

一、部署

最簡單的方式是rpm包部署： 優點：部署簡單； 缺點：路徑（目錄）固化。 yum install mysql-server yum install mysql-client 企業裡面最常用的是：二進位制部署： 優點：路徑（目錄）定製化； 缺點：部署複雜。

二、二進位制部署如何進行

先將MySQL和JDK安裝包上傳到/usr/local目錄

在進行檔案傳輸的時候，可以使用sftp (alt+p)方式進行傳輸檔案，也經常使用rz命令進行圖形化的方式傳輸檔案。 當rz命令無效時，執行如下指令進行安裝即可：yum install lrzsz -y（免輸）

1、將JDK上傳完之後解壓：[[email protected] java]# tar -xzvf jdk-8u45-linux-x64.gz 2、修改使用者和使用者組（坑）：[[email protected] java]# ll total 169216 drwxr-xr-x 8 uucp 143 4096 Apr 11 2015 jdk1.8.0_45（修改此使用者和使用者組） -rw-r–r-- 1 root root 173271626 Sep 16 18:46 jdk-8u45-linux-x64.gz [[email protected] java]# chown -R root:root jdk1.8.0_45（修改命令）

3、配置全域性環境變數：[[email protected] java]# vi /etc/profile 按G鍵進入行尾輸入兩行命令： export JAVA_HOME=/usr/java/jdk1.8.0_45

export PATH=$ JAVA_HOME/bin:$ RZDATA_HOME/bin:$PATH 儲存退出 4、生效環境變數： [[email protected] java]# source /etc/profile [[email protected] java]# which java /usr/java/jdk1.8.0_45/bin/java [[email protected]

if user mysqladmin is existing,please execute the following command of usermod.

##[[email protected] local]]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

copy 環境變數配置檔案至mysqladmin使用者的home目錄中,為了以下步驟配置個人環境變數

[[email protected] local]# cp /etc/skel/.* /usr/local/mysql [[email protected] local]# cp /etc/skel/.* /usr/local/mysql cp: omitting directory `/etc/skel/.’

cp: omitting directory `/etc/skel/…’ （5）Create /etc/my.cnf(640) #defualt start: /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf [[email protected] mysql]# cd /etc/ [[email protected] etc]# touch my.cnf [[email protected] etc]# vi my.cnf （dG刪除已有的內容，黏貼以下內容） [client] port = 3306 socket = /usr/local/mysql/data/mysql.sock

（7）Again install [[email protected] ~]$ scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data WARNING: The host ‘hadoopooo’ could not be looked up with /usr/local/mysql/bin/resolveip. This probably means that your libc libraries are not 100 % compatible with this binary MySQL version. The MySQL daemon, mysqld, should work normally with the exception that host name resolving will not work. This means that you should use IP addresses instead of hostnames when specifying MySQL privileges !

To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands:

/usr/local/mysql/bin/mysqladmin -u root password ‘new-password’ /usr/local/mysql/bin/mysqladmin -u root -h hadoopooo password ‘new-password’

Alternatively you can run:

/usr/local/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd . ; /usr/local/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

WARNING: Found existing config file /usr/local/mysql/my.cnf on the system. Because this file might be in use, it was not replaced, but was used in bootstrap (unless you used --defaults-file) and when you later start the server. The new default config file was created as /usr/local/mysql/my-new.cnf, please compare it with your file and take the changes you need.

WARNING: Default config file /etc/my.cnf exists on the system This file will be read by default by the MySQL server If you do not want to use this, either remove it, or use the –defaults-file argument to mysqld_safe when starting the server
