mysql5.6二进制安装

（该实验我在centos8的机器上操作成功）

所谓的二进制安装就相当于windoes的绿色安装 ，和编译安装的区别还是大的，要让别人提供的路安装目录）

1.创建用户
[root12:17 PMcentos7 ~]  groupadd -r -g 306  mysql
[root12:25 PMcentos7 ~]  useradd -r -g mysql -u  306 -d /data/mysql/ mysql

2.创建逻辑卷，将逻辑卷挂载，逻辑卷里面安装 mysql5.6
[root12:27 PMcentos7 ~]#pvcreate  -ff  /dev/sda3
[root12:29 PMcentos7 ~]#vgcreate vg0  /dev/sda3
[root12:29 PMcentos7 ~]   lvcreate -n mysql -l 100%free vg0
[root12:31 PMcentos7 ~]#mkfs.ext4 /dev/vg0/mysql 

3.挂载，设置开机就挂载
[root12:31 PMcentos7 ~]#vim  /etc/fstab
UUID=0b7d8060-c8ad-4958-9013-5eed0f8d3cae  /data/mysql       ext4    defaults 0  0 
[root12:35 PMcentos7 ~]#mount  -a

4.解压，创建软链接
[root12:43 PMcentos7 /usr/local]#tar xvf mysql-5.6.47-linux-glibc2.12-x86_64.tar.gz 
ln -s  mysql-5.6.47-linux-glibc2.12-x86_64 mysql

5.修改软链接的属组属主
[root11:20 AMcentos8 /usr/local]#chown -R   root.root mysql/  
[root11:20 AMcentos8 /usr/local]#ll mysql/
total 236
drwxr-xr-x  2 root root   4096 May 12 11:15 bin
drwxr-xr-x  3 root root     18 May 12 11:15 data
drwxr-xr-x  2 root root     55 May 12 11:15 docs
drwxr-xr-x  3 root root   4096 May 12 11:15 include
drwxr-xr-x  3 root root    316 May 12 11:15 lib
-rw-r--r--  1 root root 218394 Nov 27  2019 LICENSE
drwxr-xr-x  4 root root     30 May 12 11:15 man
drwxr-xr-x 10 root root    291 May 12 11:15 mysql-test
-rw-r--r--  1 root root    587 Nov 27  2019 README
drwxr-xr-x  2 root root     30 May 12 11:15 scripts
drwxr-xr-x 28 root root   4096 May 12 11:15 share
drwxr-xr-x  4 root root   4096 May 12 11:15 sql-bench
drwxr-xr-x  2 root root    136 May 12 11:15 support-files

6.指定服务器的配置文件：

[root11:50 AMcentos8 /usr/local/mysql/support-files]#vim /etc/my.cnf
[mysqld]
datadir=/data/mysql
#创建数据库
7  ./scripts/mysql_install_db  该文件创建数据库 （和bin在同一级目录，要用相对路径）
[root11:26 AMcentos8 /usr/local/mysql]#./scripts/mysql_install_db --datadir=/data/mysql/  --user=mysql
 #此时的数据库里面已经生成了文件
[root11:29 AMcentos8 /usr/local/mysql]#ll /data/mysql/
total 110604
-rw-rw---- 1 mysql mysql 12582912 May 12 11:27 ibdata1
-rw-rw---- 1 mysql mysql 50331648 May 12 11:27 ib_logfile0
-rw-rw---- 1 mysql mysql 50331648 May 12 11:27 ib_logfile1
drwx------ 2 mysql mysql     4096 May 12 11:27 mysql
drwx------ 2 mysql mysql     4096 May 12 11:27 performance_schema
drwx------ 2 mysql mysql     4096 May 12 11:27 test

8. 将启动脚本的文件复制到/etc/init.d目录下
[root11:30 AMcentos8 /usr/local/mysql/support-files]#cp mysql.server /etc/init.d/
#因为bin下面全部是执行客服端的脚本文件 因此将其添加到环境变量
[root11:36 AMcentos8 /usr/local/mysql/support-files]#ls /usr/local/mysql/bin/
innochecksum       mysqlbug                    mysqldumpslow              mysqltest_embedded
msql2mysql         mysqlcheck                  mysql_embedded             mysql_tzinfo_to_sql
myisamchk          mysql_client_test           mysql_find_rows            mysql_upgrade
myisam_ftdump      mysql_client_test_embedded  mysql_fix_extensions       mysql_waitpid
myisamlog          mysql_config                mysqlhotcopy               mysql_zap
myisampack         mysql_config_editor         mysqlimport                perror
my_print_defaults  mysql_convert_table_format  mysql_plugin               replace
mysql              mysqld                      mysql_secure_installation  resolveip
mysqlaccess        mysqld-debug                mysql_setpermission        resolve_stack_dump
mysqlaccess.conf   mysqld_multi                mysqlshow
mysqladmin         mysqld_safe                 mysqlslap
mysqlbinlog        mysqldump                   mysqltest

9. 为了让客服端的命令容易使用，添加环境变量
[root11:39 AMcentos8]#echo 'PATH=/usr/local/mysql/bin:$PATH' >/etc/profile.d/mysql.sh
[root11:39 AMcentos8 /usr/local/mysql/support-files]#.  /etc/profile.d/mysql.sh 
#开启服务端
[root11:40 AMcentos8 /usr/local/mysql/support-files]#service mysql.server start
Starting MySQL SUCCESS! 
#客服端连接服务器失败
[root11:40 AMcentos8 /usr/local/mysql/support-files]#mysql
mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

# 安装依赖包
 yum install libncurses*
yum install libaio* -y
#再次客服端连接服务器
mysql> 
#由于没有进入mysql数据库，所以用mysql.uesr
mysql> select user,password,host from mysql.user;
+------+----------+-----------+
| user | password | host      |
+------+----------+-----------+
| root |          | localhost |
| root |          | centos8   |
| root |          | 127.0.0.1 |
| root |          | ::1       |

|      |          | centos8   |
+------+----------+-----------+

10  安全加固
[root12:04 PMcentos8]#mysql_secure_installation 
11 设置开启自动启动
[root12:15 PMcentos8 ~]#vim /etc/rc.d/rc.local 
touch /var/lock/subsys/local
/etc/init.d/mysql.server start  
[root12:15 PMcentos8 ~]#chmod +x  /etc/rc.d/rc.local
