LNMP架构的源码编译

一、LNMP架构的编译安装

1. 安装nginx服务

（1）关闭防火墙

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# setenforce 0
setenforce: SELinux is disabled

（2）安装依赖包

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

（3）创建运行用户

[root@localhost ~]# useradd -M -s /sbin/nologin nginx

（4）编译安装

[root@localhost ~]# cd /opt
[root@localhost opt]# tar zxvf nginx-1.15.9.tar.gz -C /opt
[root@localhost opt]# cd nginx-1.15.9/
[root@localhost nginx-1.15.9]# ./configure /
> --prefix=/usr/local/nginx /
> --user=nginx /
> --group=nginx /
> --with-http_stub_status_module
[root@localhost nginx-1.15.9]# make -j 2 && make install
    #make -j2是给与的安装核数，越大越快（注意机器最好不要超过机器本身核数）

（5）优化路径

[root@localhost nginx-1.15.9]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

（6）添加nginx系统服务

[root@localhost nginx-1.15.9]# vim /lib/systemd/system/nginx.service
 
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
 
[root@localhost nginx-1.15.9]# chmod 754 /lib/systemd/system/nginx.service
[root@localhost nginx-1.15.9]# systemctl start nginx.service
[root@localhost nginx-1.15.9]# systemctl enable nginx.service
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.

2. 安装mysql服务

（1）安装mysql环境依赖包

[root@localhost nginx-1.15.9]# yum -y install /
> ncurses /
> ncurses-devel /
> bison /
> cmake

（2）创建运行用户

[root@localhost nginx-1.15.9]# useradd -M -s /sbin/nologin mysql

（3）编译安装

[root@localhost nginx-1.15.9]# cd /opt
[root@localhost opt]# tar zxvf mysql-boost-5.7.20.tar.gz
[root@localhost opt]# 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_EXTRA_CHARSETS=all /
> -DWITH_INNOBASE_STORAGE_ENGINE=1 /
> -DWITH_ARCHIVE_STORAGE_ENGINE=1 /
> -DWITH_BLACKHOLE_STORAGE_ENGINE=1 /
> -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 /
> -DMYSQL_DATADIR=/usr/local/mysql/data /
> -DWITH_BOOST=boost /
> -DWITH_SYSTEMD=1
[root@localhost mysql-5.7.20]# make -j 2 && make install

（4）修改mysql配置文件

[root@localhost mysql-5.7.20]# vim /etc/my.cnf
#删除全部内容后编辑
[client]
port = 3306
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
bind-address = 0.0.0.0
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
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

（5）更改mysql安装目录和配置文件的属主数组

[root@localhost mysql-5.7.20]# chown -R mysql:mysql /usr/local/mysql/
[root@localhost mysql-5.7.20]# chown mysql:mysql /etc/my.cnf

（6）设置路径环境变量

[root@localhost mysql-5.7.20]# echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile
[root@localhost mysql-5.7.20]# source /etc/profile

（7）初始化数据库

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

（8）添加mysqld系统服务

[root@localhost bin]# cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
[root@localhost bin]# systemctl daemon-reload
[root@localhost bin]# systemctl start mysqld.service
[root@localhost bin]# systemctl enable mysqld
Created symlink from /etc/systemd/system/multi-user.target.wants/mysqld.service to /usr/lib/systemd/system/mysqld.service.

（9）修改mysql的登录密码

[root@localhost bin]# mysqladmin -u root -p password "abc123"
Enter password: 
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

（10）授权远程登录

[root@localhost bin]# mysql -u root -p
Enter password:

mysql> grant all privileges on *.* to 'root'@'%' identified by 'abc123';
Query OK, 0 rows affected, 1 warning (0.00 sec)

3. 安装配置php解析环境

（1）安装环境依赖包

[root@localhost bin]# yum -y install gd /
> libjpeg libjpeg-devel /
> libpng libpng-devel /
> freetype freetype-devel /
> libxml2 libxml2-devel /
> zlib zlib-devel /
> curl curl-devel /
> openssl openssl-devel

（2）编译安装

[root@localhost bin]# cd /opt
[root@localhost opt]# tar jxvf php-7.1.10.tar.bz2
[root@localhost opt]# cd php-7.1.10
[root@localhost php-7.1.10]# ./configure /
> --prefix=/usr/local/php /
> --with-mysql-sock=/usr/local/mysql/mysql.sock /
> --with-mysqli /
> --with-zlib /
> --with-curl /
> --with-gd /
> --with-jpeg-dir /
> --with-png-dir /
> --with-freetype-dir /
> --with-openssl /
> --enable-fpm /
> --enable-mbstring /
> --enable-xml /
> --enable-session /
> --enable-ftp /
> --enable-pdo /
> --enable-tokenizer /
> --enable-zip
[root@localhost php-7.1.10]# make -j 2 && make install

（3）路径优化

[root@localhost php-7.1.10]# ln -s /usr/local/php/bin/* /usr/local/bin/
[root@localhost php-7.1.10]# ln -s /usr/local/php/sbin/* /usr/local/sbin/

（4）调整php配置文件

php有三个配置文件，分别是：
主配置文件php.ini
进程服务配置文件php-fpm.conf
扩展配置文件www.conf

1. 调整主配置文件

[root@localhost php-7.1.10]# cp /opt/php-7.1.10/php.ini-development /usr/local/php7/php.ini
#在测试环境时使用php.ini-development文件，而在生产环境时使用php.ini-production文件
[root@localhost php-7.1.10]# vim /usr/local/php/lib/php.ini
 
#1170行，修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
#939行，取消注释，修改
date.timezone = Asia/Shanghai
 
[root@localhost php-7.1.10]# php -m   #验证安装的模块
[PHP Modules]

Phar
posix

[Zend Modules]

1. 调整进程服务配置文件

[root@localhost php-7.1.10]# cd /usr/local/php/etc/
[root@localhost etc]# cp php-fpm.conf.default php-fpm.conf
[root@localhost etc]# vim php-fpm.conf
 
#17行，删除注释符号“;”
pid = run/php-fpm.pid

1. 调整扩展配置文件

[root@localhost etc]# cd /usr/local/php/etc/php-fpm.d/
[root@localhost php-fpm.d]# cp www.conf.default www.conf

（5）启动php-fpm

PHP-FPM(FastCGI Process Manager：FastCGI 进程管理器)是一个 PHPFastCGI 管理器， 由于Nginx服务器不能处理动态页面，需要由 Nginx 把动态请求交给 php-fpm 进程进行解析。

[root@localhost php-fpm.d]# /usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini
[root@localhost php-fpm.d]# netstat -anpt | grep 9000
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      33883/php-fpm: mast 
[root@localhost php-fpm.d]# cd /opt/php-7.1.10/sapi/fpm
[root@localhost fpm]# cp php-fpm.service /usr/lib/systemd/system/php-fpm.service
[root@localhost fpm]# systemctl restart php-fpm.service

（6）配置nginx支持php解析

[root@localhost fpm]# vim /usr/local/nginx/conf/nginx.conf
 
#65行-71行，取消注释，修改第69行，将/scripts 修改为nginx的工作目录
        location ~ /.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
            include        fastcgi_params;
        }
 
[root@localhost fpm]# systemctl restart nginx.service

（7）验证php测试页

[root@localhost fpm]# vim /usr/local/nginx/html/index.php
 
<?php
phpinfo();
?>

（8）验证数据库工作是否正常

[root@localhost fpm]# mysql -u root -p
Enter password:

Type 'help;' or '/h' for help. Type '/c' to clear the current input statement.
 
mysql> CREATE DATABASE bbs;
Query OK, 1 row affected (0.00 sec)
 
mysql> GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY 'admin123';
Query OK, 0 rows affected, 1 warning (0.00 sec)
 
mysql> flush privileges;
Query OK, 0 rows affected (0.03 sec)
 
mysql> quit
Bye
[root@localhost fpm]# vim /usr/local/nginx/html/index.php
 
<?php
$link=mysqli_connect('192.168.159.11','bbsuser','admin123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

4.部署Discuz!社区论坛web应用

（1）解压论坛软件

[root@localhost fpm]# cd /opt
[root@localhost opt]# unzip Discuz_X3.4_SC_UTF8.zip  -d /opt/dis

（2）新建web目录

[root@localhost opt]# cd /opt/dis/dir_SC_UTF8/
[root@localhost dir_SC_UTF8]# cp -r upload/ /usr/local/nginx/html/bbs/

（3）调整论坛目录的权限

[root@localhost dir_SC_UTF8]# cd /usr/local/nginx/html/bbs/
[root@localhost bbs]# chmod -R 777 ./{config,data,uc_server,uc_client}

（4）安装bbs

（5）访问

用户访问页面：http://IP地址/bbs/index.php

管理访问页面：http://IP地址/bbs/admin.php
