MySQL 5.6.23部署

1.jdk1.8.0安装 （JDK=java development kit）

[root@hadoop000 ~]#rz //上传 jdk-8u45-linux-x64.gz压缩包
[root@hadoop000 ~]#mkdir -p /usr/java
[root@hadoop000 ~]#cd /usr/java
[root@hadoop000 java]#mv /root/ jdk-8u45-linux-x64.gz ./ 
[root@hadoop000 java]#tar -xzvf jdk-8u45-linux-x64.gz
[root@hadoop000 java]#chown  -R  root:root   jdk1.8.0_45
[root@hadoop000 java]#vi /etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_45export 
PATH=$JAVA_HOME/bin:$PATH

[root@hadoop000 java]#source /etc/profile
[root@hadoop000 java]#which java

2.MySQL部署

[root@hadoop000 ~]#cd /usr/local
[root@hadoop000 local]#rz //上传mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz压缩包
[root@hadoop000 local]#tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@hadoop000 local]#mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql                                 //（文件夹重命名，用mv命令）
[root@hadoop000 local]#groupadd -g 101 dba
[root@hadoop000 local]#useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin  //（若用户mysqladmin已经存在，则使用usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin命令）
[root@hadoop000 local]#id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
[root@hadoop000 local]# passwd mysqladmin

[root@hadoop000 local]#  ll -a mysql            //发现没有环境变量文件.bash_profile
[root@hadoop000 local]#cp /etc/skel/.* /usr/local/mysql                 
//可从其他地方复制一个环境变量文件.bash_profile过来，不做这一步会出现“-bash-4.2$”而不是“[mysqladmin@hadoop000 ~]$”

3.Configure mysql service and boot auto start

[mysqladmin@hadoop000 ~]$su - root //切换至root用户设置服务开机自启动
[mysqladmin@hadoop000 ~]$  cd /usr/local/mysql
[root@hadoop000 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
[root@hadoop000 mysql]#chmod +x /etc/rc.d/init.d/mysql
[root@hadoop000 mysql]#chkconfig --del mysql //之前没有的话就不用执行此步骤了
[root@hadoop000 mysql]#chkconfig --add mysql
[root@hadoop000 mysql]#chkconfig --level 345 mysql on
[root@hadoop000 mysql]# vi /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

su - mysqladmin -c "/etc/init.d/mysql start --federated"

4.Start mysql and to view process and listening

[root@hadoop000 mysql]#  su - mysqladmin
[mysqladmin@hadoop000 ~]$ pwd //检查是否在/usr/local/mysql路径下
[mysqladmin@hadoop000 ~]$ rm -rf my.cnf
[mysqladmin@hadoop000 ~]$ bin/mysqld_safe &
[mysqladmin@hadoop000 ~]$ ps -ef|grep mysqld
mysqlad+ 18196 18149  0 15:54 pts/2    00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe
mysqlad+ 18839 18196  0 15:54 pts/2    00:00:00 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --log-error=/usr/local/mysql/data/hostname.err --pid-file=/usr/local/mysql/data/hostname.pid --socket=/usr/local/mysql/data/mysql.sock --port=3306
mysqlad+ 19784 18149  0 16:00 pts/2    00:00:00 grep --color=auto mysqld
[mysqladmin@hadoop000 ~]$ netstat -tulnp | 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.)
tcp6       0      0 :::3306                 :::*                    LISTEN      18839/mysqld        

5.登录mysql

[mysqladmin@hadoop000 ~]$ service mysql status
 SUCCESS! MySQL running (18839)
[mysqladmin@hadoop000 ~]$ mysql
