linux下jdk，mysql的部署
阿新 • • 發佈：2018-11-16
將jdk，mysql解壓
1注意解壓後，jdk的所屬使用者和使用者組可能要修改
[[email protected] java]# ll
total 169220
drwxr-xr-x. 8 uucp 143 4096 Apr 11 2015 jdk1.8.0_45
-rw-r--r--. 1 root root 173271626 Oct 24 17:25 jdk-8u45-linux-x64.gz
[[email protected] java]# chown -R root:root jdk1.8.0_45/
2配置java環境檔案/etc/profile,生效
[[email protected] java]# vi /etc/profile
[[email protected] java]# source /etc/profile
[[email protected] java]# which java
/usr/java/jdk1.8.0_45/bin/java
[[email protected] java]# java -version
java version "1.8.0_45"
3如果不熟悉環境，可以先檢查一下mysql有沒有被安裝過
[[email protected] java]# ps -ef|grep mysqld
root 2580 2428 0 16:09 pts/2 00:00:00 grep mysqld
[ 4建立mysql使用者和組
[[email protected] local]# groupadd -g 101 dba
[[email protected] local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
useradd: warning: the home directory already exists.
Not copying any file from skel directory into it.
[ 這裡先指定組名和對應的數字，514指的是建立的使用者id就是514，-g指定使用者的主組，-G副組，-d使用者建立之後的家目錄，使用者名稱稱叫做mysqladmin。這裡的警告是丟失環境變數檔案。
usermod是使用者已存在，修改一下。
5複製環境配置檔案到mysqladmin使用者的home目錄
[[email protected] local]# cp /etc/skel/.* /usr/local/mysql
cp: omitting directory `/etc/skel/.'
cp: omitting directory `/etc/skel/..'
cp: omitting directory `/etc/skel/.gnome2'
cp: omitting directory `/etc/skel/.mozilla'
6建立mysql配置檔案 /etc/my.cnf(640) 這個是許可權
[[email protected] local]# cd /etc/
[[email protected] etc]# touch my.cnf
[[email protected] etc]# vi my.cnf
注意：沒進入編輯模式貼上程式碼會丟失第一行頭幾個字母

7修改配置檔案的使用者和使用者組
[[email protected] etc]# chown mysqladmin:dba /etc/my.cnf
[[email protected] etc]# chmod 640 /etc/my.cnf
[[email protected] etc]# ll my.cnf
-rw-r-----. 1 mysqladmin dba 2219 Oct 28 18:51 my.cnf
修改家目錄的
[[email protected] etc]# chown -R mysqladmin:dba /usr/local/mysql
[[email protected] etc]# chmod -R 755 /usr/local/mysql
切換看下
[[email protected] etc]# su - mysqladmin
[[email protected] ~]$ pwd
/usr/local/mysql
8建立binlog檔案，並安裝libaio包
[[email protected] ~]$ mkdir arch
[[email protected] ~]$ yum -y install libaio
[[email protected] ~]$ scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
9設定mysql服務開機自啟動等
[[email protected] local]# cd /usr/local/mysql
[[email protected] mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
[[email protected] mysql]# chmod +x /etc/rc.d/init.d/mysql
[[email protected] mysql]# chkconfig --del mysql
[[email protected] mysql]# chkconfig --add mysql
[[email protected] mysql]# chkconfig mysql on
[[email protected] mysql]# vi /etc/rc.local
增加一句
su - mysqladmin -c "/etc/init.d/mysql start --federated"
10
刪了mysql下的my.cnf，因為我們配置的再etc目錄下
[[email protected] ~]$ rm -rf my.cnf
個人環境變數配置
[[email protected] ~]$ vi .bash_profile
裡面加入
export MySQL_HOME=/usr/local/mysql
export PATH=$ MYSQL_HOME/bin:$ PATH
退出重進
[[email protected] ~]$ exit
logout
There are stopped jobs.
[[email protected] ~]$ su -mysqladmin
su: invalid option -- 'y'
Try `su --help' for more information.
[[email protected] etc]# su - mysqladmin
[[email protected] ~]$ echo $ MYSQL_HOME
/usr/local/mysql
[[email protected] ~]$ mysqld_safe &
[1] 6337
查下程序埠號等
[[email protected] ~]$ ps -ef|grep mysqld
514 3448 1 0 Oct28 pts/2 00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe
[[email protected] ~]$ netstat -nlp|grep mysql
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 :::3306 :::* LISTEN 4091/mysqld
unix 2 [ ACC ] STREAM LISTENING 35117 4091/mysqld /usr/local/mysql/data/mysql.sock
[[email protected] mysql]# service mysql status

進入mysql
[[email protected] ~]$ mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1

mysql> delete from user where user='';
Query OK, 2 rows affected (0.00 sec)
重新整理許可權
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
重進要密碼
[[email protected] ~]$ mysql -uroot -p123456
建立db，給使用者賦予檢視db的許可權
mysql> create database ruozedb;
Query OK, 1 row affected (0.00 sec)
給ruoze這個使用者（可以通過什麼ip）賦予所有許可權爭對ruozedb裡的所有表
mysql> grant all privileges on ruozedb.* to [email protected]'127.0.0.1' identified by '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
注意這裡因為上面是127，這裡也要賦值
[[email protected] ~]$ mysql -uruoze -p123456 -h127.0.0.1
因為之後要去win裝mysql圖形化介面，所以這裡還是
這樣不管是哪裡的ip都能連資料庫
mysql> update user set host='%' where user='ruoze';
mysql> flush privileges;
用dbeaver連線報錯
檢視下，有問題
mysql> show grants for 'ruoze'@'%';
據說是由於修改ip導致不識別，需要配置網絡卡
window–VM8–>linux mysql
192.168.137.1
這裡需要補充一下知識，關於網段和普通ip，如果公司電腦的ip是變化的，可以將賬戶的ip設定成一個網段
172.16.110.100 mysql
‘user’@‘172.16.110.0’ 網段
注意生產連線的時候，-p之後不直接輸入密碼，會洩露。-p時密碼，-P是埠號。
刪了重搞
mysql> drop user [email protected]'%'
-> ;
mysql> grant all privileges on ruozedb.* to [email protected]'%' identified by '123456';
