LNMP site architecture build (build architecture based LNMP Forum)

I. Overview

LNMP (Linux-Apache-MySQL-PHP) website architecture is the internationally popular Web framework that includes: Linux operating system, Nginx web server, MySQL database, Perl, PHP or Python programming language, all components of the products are open source software .

Second, the experimental environment

Open a Linux virtual machine in vmware used to build service

A real machine for sharing installation packages and kits.

Third, the experimental procedures

Manually compile and install Nginx ----- "install mysql -----" install php ---- "building forum

Fourth, manually compile and install Nginx

Installation Environment bags, tool kits

[root@localhost ~]# yum install gcc gcc-c++ pcre* zlib-devel make -y

Through the real machine to the official website to download the installation package and extract the D drive to create a new folder LNMP, open the folder sharing permissions.

Remote access and sharing LNMP mount new folder / abc directory on a Linux virtual machines under

[root@localhost ~]# mkdir /abc

Enter / abc Nginx in extracting the files to opt directory

[root@localhost abc]# cd /abc/LNMP-C7/
[root@localhost LNMP-C7]# ls
Discuz_X3.4_SC_UTF8.zip    ncurses-5.6.tar.gz   php-5.6.11.tar.bz2  php-7.1.20.tar.bz2  zend-loader-php5.6-linux-x86_64_update1.tar.gz
mysql-boost-5.7.20.tar.gz  nginx-1.12.2.tar.gz  php-7.1.10.tar.bz2  php-7.1.20.tar.gz
[root@localhost LNMP-C7]# tar zxvf nginx-1.12.2.tar.gz -C /opt

After the extraction is completed, unzip into the directory /opt/nginx-1.12.2/, create and execute the program user nginx CON
Figure script.

[root@localhost LNMP-C7]# cd /opt/nginx-1.12.2/
[root@localhost nginx-1.12.2]#  useradd -M -s /sbin/nologin nginx
[root@localhost nginx-1.12.2]# ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module

Compile and execute after installation

[root@localhost nginx-1.12.2]# make && make install

You can create a soft link after the installation is complete, convenient management command

[root@localhost nginx-1.12.2]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin

Add executed documents to facilitate the management command systemctl

[root@localhost nginx-1.12.2]#  cd /lib/systemd/system
[root@localhost nginx-1.12.2]#  vim nginx.service
[Unit]

After completion of wq to save, change the permissions to execute the document, turn off the firewall, start Nginx service

[root@localhost system]#  chmod 754 nginx.service
[root@localhost system]#  systemctl stop firewalld.service 
[root@localhost system]#  setenforce  0
[root@localhost system]#  systemctl start nginx.service 

Nginx web access verification

V. manually compile and install mysql

Installation environment package, users create a program

[root@localhost ~]#  yum -y install ncurses  ncurses-devel bison cmake
[root@localhost ~]#  useradd -s /sbin/nologin  mysql

Mysql-extracting compressed file to opt directory

[root@localhost ~]#  cd /abc/LNMP-C7/
[root@localhost LNMP-C7]#  tar zxvf mysql-boost-5.7.20.tar.gz -C /opt/

After the extraction is completed, unzip into the directory /opt/mysql-5.7.20/ execute cmake

[root@localhost LNMP-C7]# cd /opt/mysql-5.7.20/
[root@localhost mysql-5.7.20]# cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH-BLACKHOLE_STIRAGE_ENGINE=1 \
-DWITH-PERDSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1

After completing the compilation and installation

[root@localhost mysql-5.7.20]#  make && make install

After installation is complete modify permissions and mysql my.cnf configuration file, delete the original file, and then add the following to this quote.

[root@localhost mysql-5.7.20]#  chown -R mysql:mysql /usr/local/mysql/
[root@localhost mysql-5.7.20]#  vim /etc/my.cnf
[client]
port=3306
default-character-set=utf8
socket=/usr/local/mysql/mysql.sock

[mysql]
port=3306
default-character-set=utf8
socket=/usr/local/mysql/mysql.sock

[mysqld]
user=mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port=3306
character_set_server=utf8
pid-file=/usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
server-id=1

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

After editing wq save, set the environment variable

[root@localhost mysql-5.7.20]#  echo  'PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile   ##将MySQL写到本地环境配置中
[root@localhost mysql-5.7.20]#  echo 'export PATH' >> /etc/profile
##设置全局环境配置
[root@localhost mysql-5.7.20]# source /etc/profile   ##重新加载

Initialize the database

[root@localhost mysql-5.7.20]#  cd /usr/local/mysql/
[root@localhost mysql]#  bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data 
 

Easy to use to copy the MySQL systemctl management service profile to the / usr / lib / systemd / system / lower

[root@localhost mysql]#  cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
[root@localhost mysql]#  systemctl enable mysqld      ###开机自启
[root@localhost mysql]#  systemctl start mysqld.service  ###启动服务
[root@localhost mysql]# netstat -natp | grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN      2711/mysqld      

Set mysql password

[root@localhost mysql]#  mysqladmin -u root -p password
    Enter password:               ##空格
	New password:                ##新密码
