lamp (centos7) installation lamp environment

Install virtual machine under mac

Required software

VirtualBox-5.1.30-OSX.dmg virtual machine

1. CentOS-7-x86_64-Everything-1708.iso

2. mysql-5.6.31.tar.gz

wget https://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.31.tar.gz

5.7 address

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.20.tar.gz

3. php7

wget http://php.net/get/php-7.0.27.tar.gz/from/a/mirror

Continue to add...

step

One: Install the virtual machine VB, mine is the mac version, and install centos7, according to your own computer system

1.1 New:

Keep singing all the way, and the creation is complete

Select start, select the image file

Choose install, press Enter, it will install automatically

Choose a language

Installation location and network and host name in turn select settings

turn on

Set root password and create user

Can create users to choose

Wait for the installation by yourself, and restart after completion

Log in to wxq account

Switch to administrator account

Ping to see if the network is smooth:

If it is not smooth, you need to configure the network, go to the configuration file to modify

Write configuration file content

Some configuration files may be different, but basically there is no need to delete, add and modify departments

The last ONBOOT=yes turns on network access

Note: ipaddr here is based on the address displayed when you connect to the network locally. In your last paragraph, change it. For example, mine is 192.168.1.149, and I will change the virtual machine to 150. It’s 255.255 if it is not heavy. 255.0 is basically the same, no need to move

: wp save and exit

Sudo systemctl restart network.service

ip addr view IP address

Enable remote to allow remote login to the virtual machine system. The remote is port 22. If an error is reported, you need to switch to the root user and restart the firewall after enabling it, as follows:

The last key part, in the virtual machine vb settings, select the bridge network card for the network, and then restart the virtual machine to be able to remotely access

At this point, you can log in through the local ssh

ssh [email protected]

Or log in directly with ssh [email protected]

Step two:

2.1 install software

Use yum to install, here is a demonstration of installing vim

yum install vim

2.2 Install wget, because it needs to install lamp series of installation packages, such as php, mysql, etc.

yum install wget

2.3 Install php, other software is similar, just install it in the root directory, according to personal needs

wget http://php.net/get/php-7.0.27.tar.gz/from/a/mirror

tar -zxvf mirror

2.4 Install the dependency packages needed for compilation and installation, pay attention to the letter l

sudo yum install gcc gcc++ libxml2-devel

2.5 Go to the php decompression directory and compile

cd php-7.0.27

2.6 Compile and install

make

make install

Can be together

make && make install

2.7 Test whether the installation is successful

Write php file

At this time, php is not a global variable, you need to find the directory of the php execution file when running, and then test the written file

3. Install mysql5.6.31

Install the dependent software required by mysql

yum install cmake gcc-c++ ncurses-devel perl-Data-Dumper boost boost-doc boost-devel

Sudo if not root user

Then unzip it, go to the unzip package directory to cmake

cmake \

- DCMAKE_INSTALL_PREFIX=/usr/local/mysql``\

- DMYSQL_DATADIR=/mydata/mysql/data``\

- DSYSCONFDIR=/etc``\

- DMYSQL_USER=mysql \

- DWITH_MYISAM_STORAGE_ENGINE=1 \

- DWITH_INNOBASE_STORAGE_ENGINE=1 \

- DWITH_ARCHIVE_STORAGE_ENGINE=1 \

- DWITH_MEMORY_STORAGE_ENGINE=1 \

- DWITH_PARTITION_STORAGE_ENGINE=1 \

- DWITH_READLINE=1 \

- DMYSQL_UNIX_ADDR=/var/run/mysql/mysql.sock \

- DMYSQL_TCP_PORT=3306 \

- DENABLED_LOCAL_INFILE=1 \

- DENABLE_DOWNLOADS=1 \

- DEXTRA_CHARSETS=all \

- DDEFAULT_CHARSET=utf8 \

- DDEFAULT_COLLATION=utf8_general_ci \

- DENABLE_DTRACE=0 \

- DMYSQL_MAINTAINER_MODE=0 \

- DWITH_SSL:STRING=bundled \

- DWITH_ZLIB:STRING=bundled .

Note here that there is a space plus a dot at the end.

Otherwise the execution will report an error

Compile and install:

sudo make install

Start mysql using mysqld command

to be continued. . . .

Note: When setting the network card, the normal setting can be passed through the first installation, but the second setting fails, according to this setting

First configure the virtual machine to bridge mode, and then turn it on
Before you plan to modify the virtual machine IP, first ping 127.0.0.1 to see if the network card is good (if 127.0.0.1 fails to ping, then the network card is broken...)

[ root@localhost /]# ping 127.0.0.1

Before setting a static IP, you can take a look at the network card you are currently on:

[ root@localhost /]# ifconfig

1. Set the static IP of the network card ens32

[ root@localhost /]# cd /etc/sysconfig/network-scripts/        #Pay attention to the cd and "/Space between "etc"
[ root@localhost network-scripts]# 
[ root@localhost network-scripts]# ls     #View network-All files under scripts

ifcfg-lo     ifdown-ib    ifdown-post    ifdown-Team      ifup-aliases  ifup-ippp  ifup-plusb  ifup-sit       ifup-wireless

[ root@localhost network-scripts]# 

Edit with vi
[ root@localhost network-scripts]# vi ifcfg-ens32
【Click i to insert and then Esc and enter:wq to save]
[ root@localhost network-scripts]# vi ifcfg-ens32

GATEWAY=“192.168.0.1”

modify:
BOOTPROTO=“static”  #Enable static IP address
Add:
IPADDR=“192.168.0.121”  #Set IP address
GATEWAY=“192.168.0.1”  #Set the gateway, check the local computer, you can see the gateway

[Note] Save after setting!

Then restart the network:

[ root@localhost ~]# service network restart    #Restart network
Restarting network(via systemctl):[  OK  ][root@localhost ~]# 

[ root@localhost ~]# ping 192.168.0.107  #ping the IP in the LAN is normal

[ root@localhost ~]# ping www.baidu.com    #Ping Baidu domain still not working

"Ping: www.baidu.com: Name or service not known" error solution

The first step is to view ONBOOT:

[ root@localhost ~]# cd /etc/sysconfig/network-scripts/[root@localhost network-scripts]# ls
ifcfg-ens32  ifdown-bnep  ifdown-ippp  ifdown-post    ifdown-sit       ifdown-tunnel  ifup-bnep  ifup-ippp  ifup-plip   ifup-ppp     ifup-Team      ifup-wireless      network-functions-ipv6

ifdown       ifdown-ib    ifdown-isdn  ifdown-routes  ifdown-TeamPort  ifup-aliases   ifup-ib    ifup-isdn  ifup-post   ifup-sit     ifup-tunnel    network-functions
[ root@localhost network-scripts]# vi ifcfg-ens32
TYPE="Ethernet"
BOOTPROTO="static"  #Enable static IP address
DEFROUTE="yes"
PEERDNS="yes"
PEERROUTES="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_PEERDNS="yes"
IPV6_PEERROUTES="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens32"
UUID="17e371b3-5107-4d72-a58f-e8f71396fd68"
DEVICE="ens32"
ONBOOT="yes"
IPADDR=“192.168.0.121”
GATEWAY=“192.168.0.1”

Found that ONBOOT=”no” has been set to ONBOOT=”yes”

The second step is to check:
The ping command belongs to the ICMP protocol, and the ping ip address is valid. If you directly ping the website (domain name), you need to configure DNS. Edit and add nameserver as follows:

vi /etc/resolv.conf 
nameserver 8.8.8.8 
nameserver 8.8.4.4

[Note] Save after setting!

Ping again
[ root@localhost /]# ping www.baidu.com
