Linux-VMware Workstation&CentOS-5.5-i386-bin-DVD安装
【2018年6月24日 22:55:47】
VM7+CentOS5.5使用NAT方式连接互联网
1、在VMWare的菜单：“VM→Setting...”
2、在VMWare的菜单：“Edit→Virtual Network Edit...”，在弹出的对话框中单击“Restore default”。并且将“Subnet IP”设置成为："192.168.126.0"（这个IP可以自定义），
再单击“NAt Settings...”
在CentOS：
查看IP地址：
# ip addr show
·修改网卡设置：
# vim /etc/sysconfig/network-scripts/ifcfg-eth0
修改内容（192.168.126.x：x取值0~255）：
IPADDR=192.168.126.18
重启网卡：service network restart。此时就可以使用XShell连接Linux了。
ping路由
# ping 192.168.126.1
# ping 192.168.126.2
添加网关：
# vim /etc/sysconfig/network-scripts/route-eth0
内容如下：
0.0.0.0/0 via 192.168.126.2 dev eth0
重启网卡：
# service network restart
设置DNS：
# vim /etc/resolv.conf
内容如下：
nameserver 192.168.126.2
#nameserver 175.188.160.154
#meserver 175.188.160.254
#search localdomain
此时，就可ping同外网了。ping www.baidu.com。
【2018年6月30日 09:45:50】
查看IP地址：ip addr show
[root@localhost ~]# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 00:0c:29:1d:8f:97 brd ff:ff:ff:ff:ff:ff
3: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether 52:54:00:33:18:72 brd ff:ff:ff:ff:ff:ff
inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
valid_lft forever preferred_lft forever
4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast master virbr0 state DOWN group default qlen 1000
link/ether 52:54:00:33:18:72 brd ff:ff:ff:ff:ff:ff
“2:”的是网卡
如果是CentOS7，修改网卡设置如下：
vim /etc/sysconfig/network-scripts/ifcfg-ens33
需要修改内容如下，将“BOOTPROTO=dhcp”改为：“BOOTPROTO=static”、“ONBOOT=no”改为：“ONBOOT=yes”，其他三项直接添加。
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.126.28
NETMASK=225.225.225.0
GATEWAY=192.168.126.2
此时，重启网卡（service network restart）可以用XShell连接Linux了。再将DNS设置与CentOS6一样
vi /etc/resolv.conf
添加：nameserver 192.168.126.2
# Generated by NetworkManager
nameserver 192.168.126.2
wq保存退出。此时就可以ping通了。
[root@localhost ~]# ping www.baidu.com

如果无法ping通百度，请关闭关闭selinux和防火墙：
# vi /etc/selinux/config
内容如下：
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
# SELINUX=enforcing
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
将“SELINUX=enforcing”改为“SELINUX=disabled”重启后永久关闭selinux。
# 查看selinux的状态
# sestatus -v
# 这个命令可以临时关闭selinux
# setenforce 0
关闭防火墙：
# 这个命令可以临时关闭防火墙
# service iptables stop
# service ip6tables stop
# 这个命令可以永久关闭防火墙
# chkconfig iptables off
# chkconfig ip6tables off
# 这个命令可以查看防火墙的状态
# chkconfig iptables --list
# chkconfig ip6tables --list
下面是具体过程：

[root@localhost ~]# mkdir -p /usr/local/mysql/
(2)创建数据存放目录
[root@localhost ~]# mkdir -p /usr/data/mysql/
(3)创建用户及用户组和赋予数据存放目录权限
[root@localhost ~]# groupadd mysql
[root@localhost ~]# useradd -g mysql mysql
[root@localhost ~]# chown mysql.mysql -R /usr/data/mysql/
------Start Copy------
groupadd mysql
useradd -g mysql mysql
chown mysql.mysql -R /usr/data/mysql/
------End Copy------
(4)cmake（MySQL5.5以后是通过cmake来编译的）
下载：wget http://www.cmake.org/files/v2.8/cmake-2.8.4.tar.gz
解压：tar zxvf cmake-2.8.4.tar.gz
cd cmake-2.8.4
安装：./configure make && make install
[root@localhost mnt]# tar zxvf cmake-2.8.4.tar.gz
[root@localhost mnt]# cd cmake-2.8.4
[root@localhost cmake-2.8.4]# ./configure make && make install
------Start Copy------
tar zxvf cmake-2.8.4.tar.gz
cd cmake-2.8.4
./configure make && make install
------End Copy------
(5)解压mysql-5.5.20.tar.gz
[root@localhost mnt]# tar zxvf mysql-5.5.20.tar.gz
[root@localhost mnt]# cd mysql-5.5.20
------Start Copy------
tar zxvf mysql-5.5.20.tar.gz
cd mysql-5.5.20
------End Copy------
(6)编译mysql-5.5.20
[root@localhost mysql-5.5.20]#
------Start Copy------
cmake . \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ \
-DMYSQL_DATADIR=/usr/data/mysql \
-DMYSQL_UNIX_ADDR=/usr/data/mysql/mysqld.sock \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_TCP_PORT=3306 \
-DEXTRA_CHARSETS=all \-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DMYSQL_UNIX_ADDR=/usr/data/mysql/mysql.sock \
-DMYSQL_USER=mysql \
-DWITH_DEBUG=0
------End Copy------
[root@localhost mysql-5.5.20]# make && make install
(7)复制配置文件：（/mnt/mysql-5.5.20）
[root@localhost mysql-5.5.20]# cp support-files/my-medium.cnf /etc/my.cnf
[root@localhost mysql-5.5.20]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql-5.5.20]# chmod 755 /etc/init.d/mysqld
------Start Copy------
cp support-files/my-medium.cnf /etc/my.cnf
cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
------End Copy------
(8)初始化数据库（/usr/local/mysql）
[root@localhost mysql-5.5.20]# bash /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/data/mysql/
------Start Copy------
bash /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/data/mysql/
------End Copy------
(9)启动mysql服务并查看
[root@localhost mysql-5.5.20]# /etc/init.d/mysqld start
[root@localhost mysql-5.5.20]# ps -ef |grep mysql
(10)通过命令行登录管理MySQL服务器，初始密码为空
[root@localhost mysql-5.5.20]# /usr/local/mysql/bin/mysql -u root -p
(11)修改root密码，并测试
mysql> use mysql;
mysql> update user set password=PASSWORD("qqqqqq") where user='root';
mysql> FLUSH PRIVILEGES;
------Start Copy------
use mysql;
update user set password=PASSWORD("qqqqqq") where user='root';
FLUSH PRIVILEGES;
exit
------End Copy------
再次启动MySQL服务器验证修改过的密码
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
+--------------------+
4 rows in set (0.00 sec)
(12)设置MySQL开机启动
[root@localhost mysql-5.5.20]# cd /etc
[root@localhost etc]# vim rc.local
---------
7 touch /var/lock/subsys/local
8 /usr/local/apache2/bin/apachectl start
9 /etc/init.d/mysqld start
---------
[root@localhost etc]# cat rc.local
(12)创建别名：alias mysql='/usr/local/mysql/bin/mysql -u root -p'
shell脚本自动安装：
【2018年2月28日 21:32:55】
启动(包括：yum -y remove http* mysql* php*，这种一键装方式)
[root@localhost ~]# /etc/init.d/mysqld start
修改密码后：
[root@localhost ~]# mysql -uroot -p
远程连接出现Error 1130问题
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>flush privileges;
mysql>select host, user from user
对于“ERROR 1062 (23000): Duplicate entry '%-root' for key 1”报错的解决方案
mysql> update user set host='%' where user = 'root';
ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY'
然后查看了下数据库的host信息如下：
mysql> select host from user where user = 'root';
+-----------------------+
| host |
+-----------------------+
| % |
| 127.0.0.1 |
| localhost.localdomain |
+-----------------------+
3 rows in set (0.00 sec)
host已经有了%这个值，所以直接运行命令，即可用工具链接
mysql>flush privileges;
启动apache
[root@localhost ~]# service httpd start
Starting httpd: [ OK ]
