# chown -R root /usr/local/mysql/
# chown -R mysql /usr/local/mysql/data/
MYSQL入门--8.设置mysql开机自启动
MYSQL入门

# source /etc/profile
MYSQL入门 CentOS 6.5最小化编译安装mysql 5.5.35配置多实例
MYSQL入门1、关闭防火墙
MYSQL入门
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
MYSQL入门2、关闭selinux
MYSQL入门
12 [root@mysql ~]# setenforce 0
[root@mysql ~]# vim /etc/sysconfig/selinux
MYSQL入门修改下面这一行；
MYSQL入门
SELINUX=disabled
12 [root@mysql ~]# getenforce
Permissive
MYSQL入门3、安装mysql依赖包及编译工具；
MYSQL入门
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
MYSQL入门4、安装前准备；
MYSQL入门4.1、安装路径:
MYSQL入门
1 [root@mysql ~]# mkdir /usr/local/mysql
MYSQL入门4.2、数据库路径:
MYSQL入门
1 [root@mysql ~]# mkdir /data/mysql -p
MYSQL入门4.3、创建用户和用户组
MYSQL入门
12 [root@mysql ~]# groupadd mysql
[root@mysql ~]# useradd -r -g mysql -s /bin/false mysql
MYSQL入门4.4、赋予数据存放目录权限
MYSQL入门
1 [root@mysql ~]# chown mysql:mysql -R /data/mysql
MYSQL入门5、编译安装mysql 5.5.35
MYSQL入门
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
MYSQL入门6、创建多实例数据库文件存放位置;
MYSQL入门
12345678 [root@mysql ~]# mkdir -p /data/{3306,3307}/data
[root@mysql ~]# tree /data
/data
|-- 3306
| `-- data
`-- 3307
`-- data
4 directories, 0 files
MYSQL入门7、修改配置文件(my.cnf)如下行,分别放入3306、3307目录当中；
MYSQL入门
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
MYSQL入门8、初始化数据库；
MYSQL入门注意：初始化数据库时需要指定不同的数据目录
MYSQL入门
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
MYSQL入门9、启动多实例,启动脚本可以加入到开机自启动文件中.
MYSQL入门
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 &
MYSQL入门9.1、查看端口；
MYSQL入门
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
MYSQL入门10、登录多实例数据库
MYSQL入门
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
MYSQL入门11、关闭mysql多实例方式
MYSQL入门
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
