Centos mini 6.5 安装mysql5.6.4
1.下载安装包
云盘地址:http://pan.baidu.com/s/1bpsgXUf
安装需要包工具
yum -y install wget vim lrzsz tar
2.更换yum源(个人在yum装有些包出问题就换阿里云的yum源了)
这里更换为阿里云yum源
cd /etc/yum.repos.d/
mv CentOS-Bose.repo CentOS-Bose.repo.bak
wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
Yum makecache
3.创建mysql用户
useradd mysql //已经有的不需要创建
4.卸载原来的mysql rpm包
rpm -qa|grep mysql //查询是否有相关包
Yum -y remove *mysql* //我这里用yum卸载的
5.关闭防火墙,关闭selinux
Service iptables stop //个人习惯性关闭防火墙
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
setenforce 0
6.安装所需依赖包
yum -y install make gcc gcc-c++ gcc-gfortran flexbison file libtool libtool-libs autoconf kernel-devel libjpeg libjpeg-devellibpng libpng-devel libpng10 libpng10-devel gd gd-devel freetype freetype-devellibxml2 libxml2-devel zlib zlib-devel glib2 glib2-devel bzip2 bzip2-devellibevent libevent-devel ncurses ncurses-devel curl curl-devel e2fsprogse2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-develgettext gettext-devel ncurses-devel gmp-devel pspell-devel unzip libcap lsof
7.安装cmake
Mysql5.6版本后需要cmake来配置编译
tar -zxvf cmake-2.8.5.tar.gz
cd cmake-2.8.5
./configure
gmake && gmake install
8.开始安装mysql
tar -zxvf mysql-5.6.4-m7.tar.gz
cd mysql-5.6.4-m7
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/etc \
-DMYSQL_USER=mysql \
-DWITH_MYISAM_STORAGE_ENGINE=1 \

make && make install

单实例的的安装操作
9.安装完相关操作
修改mysql安装目录权限
Chmod +w /usr/local/msyql
Chown -R msyql.msyql /usr/local/mysql
//在启动MySQL服务时,会按照一定次序搜索my.cnf,先在/etc目录下找,找不到则会搜索”$basedir/my.cnf”就是安装目录下/usr/local/mysql/my.cnf,这是新版MySQL的配置文件的默认位置!注意:在CentOS 6.x版操作系统的最小安装完成后,在/etc目录下会存在一个my.cnf,需要将此文件更名为其他的名字。如:/etc/my.cnf.bak,否则,该文件会干扰源码安装的MySQL的正确配置,造成无法启动。由于我们已经卸载了最小安装完成后的mysq库所以,就没必要操作了。
cd support-files/
如果还有my.cnf请备份
mv /etc/my.cnf /etc/my.cnf.bak
复制配置文件到etc下
cp my-medium.cnf /etc/my.cnf
//执行初始化配置脚本,创建系统自带的数据库和表,注意配置文件的路径
/usr/local/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf--basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
//拷贝mysql安装目录下support-files服务脚本到init.d目录
#拷贝脚本
cp support-files/mysql.server /etc/init.d/mysqld
#赋予权限
chmod +x /etc/init.d/mysqld
#设置开机启动
chkconfig mysqld on
#启动MySQL
service mysqld start 或者 /etc/init.d/mysql start
MySQL5.6.x启动成功后,root默认没有密码,我们需要设置root密码。设置之前,我们需要先设置PATH,要不,不能直接调用mysql
修改/etc/profile文件
vim /etc/profile
在文件末尾添加
PATH=/usr/local/mysql/bin:$PATH
export PATH
#让配置立即生效
source /etc/profile
#登陆测试,默认是没有密码,直接回车就可进入
mysql -uroot -p
设置mysqlroot用户密码
mysqladmin -u root password "newpass"
#如果root已经设置过密码,采用如下方法
mysqladmin -u root password oldpass "newpass"
#验证mysql安装路径
ls -ld /usr/local/mysql/
多实例的安装
接着上面源码包安装完成开始
1,创建多实例数据库文件夹
mkdir -pv/usr/local/mysql/data/{3306,3307,3308}
chown -Rmysql.mysql /usr/local/mysql/data/
2,初始化数据库
cd/usr/local/mysql
scripts/mysql_install_db--user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/3306/
scripts/mysql_install_db--user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/3307/
scripts/mysql_install_db--user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/3308/
3,准备配置文件#提供多配置文件模板
cd bin
./mysqld_multi--example > /usr/local/mysql/data/multi.cnf
4,修改模板文件 (不用的注释掉)
vim /usr/local/mysql/data/multi.cnf
[mysqld_multi]cd
mysqld = /usr/local/mysql/bin/mysqld_safe
mysqladmin =/usr/local/mysql/bin/mysqladmin
user = root
#password = root #设置了密码后一定要开启,不然命令停止会有问题 (三个实例数据库密码一样)
[mysqld1]
socket = /tmp/mysql.sock1
port = 3306
pid-file = /usr/local/mysql/data/3306/mysql.pid
datadir = /usr/local/mysql/data/3306/
[mysqld2]
socket = /tmp/mysql.sock2
port = 3307
pid-file = /usr/local/mysql/data/3307/mysql.pid
datadir = /usr/local/mysql/data/3307/
#language = /usr/local/mysql/share/mysql/english
#user = unix_user1
[mysqld3]
#mysqld = /path/to/mysqld_safe
#ledir = /path/to/mysqld-binary/
#mysqladmin =/path/to/mysqladmin
socket = /tmp/mysql.sock3
port = 3308
pid-file = /usr/local/mysql/data/3308/mysql.pid
datadir = /usr/local/mysql/data/3308/
#language = /usr/local/mysql/share/mysql/swedish
#user = unix_user2
5,修改/etc/profile文件
vim /etc/profile
在文件末尾添加
PATH=/usr/local/mysql/bin:$PATH
#让配置立即生效
source /etc/profile
6,启动msyql数据库
mysqld_multi--defaults-file=/usr/local/mysql/data/multi.cnf start 1,2,3
查看端口状态
netstat -anpt|grep mysqld
tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN 25470/mysqld
tcp 0 0 0.0.0.0:3308 0.0.0.0:* LISTEN 25476/mysqld
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 25453/mysqld
7,设置mysql密码
mysqladmin-uroot -S /tmp/mysql.sock1 password "root"
mysqladmin-uroot -S /tmp/mysql.sock2 password "root"
mysqladmin-uroot -S /tmp/mysql.sock3 password "root"
8,进入数据库
Mysql -S/tmp/mysql.sock1 -proot
9,关闭数据库3种方法。
mysqladmin -S/tmp/mysql.sock1 shutdown -proot
mysqld_multi--defaults-file=/usr/local/mysql/data/multi.cnf stop 1,2,3
