这篇文章主要介绍了centos编译安装mysql 5.6及安装多个mysql实例详解,需要的朋友可以参考下

--1.为mysql新建组和用户

# useradd -M -s /sbin/nologin mysql

--2.安装需要的库,编译器

# yum install ncurses-devel openssl-devel cmake -y

--3.解压

# tar zxvf mysql-5.6.35.tar.gz
# cd mysql-5.6.35

--4.编译安装

# cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DMYSQL_USER=mysql \
-DWITH_DEBUG=0 \
-DWITH_SSL=system
# make
# make install

--5.拷贝模版,作为配置文件

# cp support-files/my-default.cnf /etc/my.cnf

--6.设置mysql权限

# chown -R mysql.mysql /usr/local/mysql/

--7.初始化mysql数据库

# /usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
# chown -R root /usr/local/mysql/
# chown -R mysql /usr/local/mysql/data/

--8.设置mysql开机自启动

# cp support-files/mysql.server /etc/init.d/mysqld
# chmod +x /etc/init.d/mysqld
# chkconfig mysqld on

--9.测试并运行mysql

#service mysqld start

--10.修改mysql管理员密码

#/usr/local/mysql/bin/mysqladmin -u root password '要设置的密码'

--11.使用用户登录mysql

# /usr/local/mysql/bin/mysql -u root -p

--12.加入环境变量

# echo 'PATH=/usr/local/mysql/bin/:$PATH' >>/etc/profile
# source /etc/profile

CentOS 6.5最小化编译安装mysql 5.5.35配置多实例

1、关闭防火墙

1234567 [root@mysql ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter   [ OK ]
iptables: Flushing firewall rules:       [ OK ]
iptables: Unloading modules:        [ OK ]
[root@mysql ~]# chkconfig iptables off
[root@mysql ~]# chkconfig iptables --list
iptables  0:off 1:off 2:off 3:off 4:off 5:off 6:off

2、关闭selinux

12 [root@mysql ~]# setenforce 0
[root@mysql ~]# vim /etc/sysconfig/selinux

修改下面这一行;

SELINUX=disabled
12 [root@mysql ~]# getenforce 
Permissive

3、安装mysql依赖包及编译工具;

1234 [root@mysql ~]# yum install libaio-devel -y
[root@mysql ~]# yum install -y ncurses-devel
[root@mysql ~]# yum install -y gcc gcc-c++ 
[root@mysql ~]# yum install -y cmake

4、安装前准备;

4.1、安装路径:

1 [root@mysql ~]# mkdir /usr/local/mysql

4.2、数据库路径:

1 [root@mysql ~]# mkdir /data/mysql -p

4.3、创建用户和用户组

12 [root@mysql ~]# groupadd mysql
[root@mysql ~]# useradd -r -g mysql -s /bin/false mysql

4.4、赋予数据存放目录权限

1 [root@mysql ~]# chown mysql:mysql -R /data/mysql

5、编译安装mysql 5.5.35

1234567 [root@mysql ~]# yum install -y lrzsz
root@mysql ~]# mkdir /package
[root@mysql ~]# cd /package/
[root@mysql package]# tar xf mysql-5.5.32.tar.gz 
[root@mysql package]# cd mysql-5.5.32
[root@mysql mysql-5.5.32]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql 
-DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock 
-DDEFAULT_CHARSET=utf8 
-DDEFAULT_COLLATION=utf8_general_ci 
-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk 
-DWITH_INNOBASE_STORAGE_ENGINE=1 
-DWITH_READLINE=1 
-DENABLED_LOCAL_INFILE=1 
-DMYSQL_DATADIR=/data/mysql/ 
-DMYSQL_USER=mysql 
-DMYSQL_TCP_PORT=3306
[root@mysql mysql-5.5.32]# make && make install

6、创建多实例数据库文件存放位置;

12345678 [root@mysql ~]# mkdir -p /data/{3306,3307}/data
[root@mysql ~]# tree /data
/data
|-- 3306
|  `-- data
`-- 3307
  `-- data
4 directories, 0 files

7、修改配置文件(my.cnf)如下行,分别放入3306、3307目录当中;

123456789 [root@mysql 3306]# vim my.cnf 
[client]
port      = 3306
socket     = /data/3306/mysql.sock
[mysqld]
port      = 3306
socket     = /data/3306/mysql.sock
datadir     = /data/3306
server-id    = 3306

8、初始化数据库;

注意:初始化数据库时需要指定不同的数据目录

123 [root@mysql mysql-5.5.32]# cd /usr/local/mysql/
[root@mysql mysql]# scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/3306
[root@mysql mysql]# scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/3307

9、启动多实例,启动脚本可以加入到开机自启动文件中。

12 [root@mysql mysql]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/3306/my.cnf 2>&1 >/dev/null &  
[root@mysql mysql]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/3307/my.cnf 2>&1 >/dev/null &

9.1、查看端口;

12345678 [root@mysql mysql]# netstat -tunlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address        Foreign Address       State    PID/Program name  
tcp    0   0 0.0.0.0:3307        0.0.0.0:*          LISTEN   11621/mysqld    
tcp    0   0 0.0.0.0:22         0.0.0.0:*          LISTEN   1266/sshd      
tcp    0   0 0.0.0.0:3306        0.0.0.0:*          LISTEN   11338/mysqld    
tcp    0   0 :::22            :::*            LISTEN   1266/sshd      
udp    0   0 0.0.0.0:68         0.0.0.0:*                969/dhclient

10、登录多实例数据库

12 [root@mysql mysql]# /usr/local/mysql/bin/mysql -u root -p -P 3306 -S /data/3306/mysql.sock
[root@mysql mysql]# /usr/local/mysql/bin/mysql -u root -p -P 3307 -S /data/3307/mysql.sock

11、关闭mysql多实例方式

12 [root@mysql mysql]# /usr/local/mysql/bin/mysqladmin -u root -p -P 3306 -S /data/3306/mysql.sock shutdown  
[root@mysql mysql]# /usr/local/mysql/bin/mysqladmin -u root -p -P 3307 -S /data/3307/mysql.sock shutdown
cat /etc/my.cnf
