在Linux系统中做MySQL数据库主从服务器

1.网络配置
服务器A:
[root@CentOS mysql-5.0.40]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 08:00:27:56:AA:AA
inet addr:2.2.2.135 Bcast:2.255.255.255 Mask:255.0.0.0
inet6 addr: fe80::a00:27ff:fe56:aaaa/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:104974 errors:0 dropped:0 overruns:0 frame:0
TX packets:54283 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:66204315 (63.1 MiB) TX bytes:4929056 (4.7 MiB)
[root@centos mysql-5.0.40]# hostname
centos
[root@centos mysql-5.0.40]# vim /etc/hosts
2.2.2.145 centos1
2.2.2.135 centos

服务器B:
[root@centos1 ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 08:00:27:56:AA:AA
inet addr:2.2.2.145 Bcast:2.2.2.255 Mask:255.255.255.0

[root@centos1 ~]# hostname
centos1
[root@centos1 ~]# vim /etc/hosts
2.2.2.135 centos
2.2.2.145 centos1
[root@centos1 ~]# ping -c 2 2.2.2.135

2.安装mysql软件
服务器A:
[root@centos mysql-5.0.40]# yum install mysql mysql-server -y --安装mysql
[root@centos mysql-5.0.40]# /etc/init.d/mysqld restart --启动mysql
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
[root@centos mysql-5.0.40]# netstat -an |grep 3306
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN
[root@centos mysql-5.0.40]# mysql -u root -p
Enter password:
