LNMP架构的源码编译
LNMP架构的源码编译
编译安装 Nginx 服务
1.关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
2.安装相关依赖包
yum -y install pcre-devel zlib-devel gcc gcc-c++ make
3.创建运行用户
useradd -M -s /sbin/nologin nginx
4.解压软件包及配置编译安装
cd /opt
tar zxvf nginx-1.12.0.tar.gz -C /opt/
cd nginx-1.12.0/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module
make -j8 && make install
5.优化路径
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
6.将Nginx 加入系统服务
vim /lib/systemd/system/nginx.service
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
chmod 754 /lib/systemd/system/nginx.service
systemctl start nginx.service
systemctl enable nginx.service
编译安装mysql服务
1.安装Mysql环境依赖包
yum -y install \
ncurses \
ncurses-devel \
bison \
cmake
2.创建运行用户
useradd -M -s /sbin/nologin mysql
3.解压配置编译安装
cd /opt
tar zxvf mysql-boost-5.7.20.tar.gz
cd /opt/mysql-5.7.20/
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \

-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1
make -j8 && make install
4.修改mysql 配置文件
vim /etc/my.cnf
[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属组
chown -R mysql:mysql /usr/local/mysql/
chown mysql:mysql /etc/my.cnf
6.设置路径环境变量
echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile
source /etc/profile
7.初始化数据库
cd /usr/local/mysql/bin/
./mysqld
--initialize-insecure
--user=mysql
--basedir=/usr/local/mysql
--datadir=/usr/local/mysql/data
8.添加mysqld系统服务
cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
systemctl daemon-reload
systemctl start mysqld.service
systemctl enable mysqld
9.修改mysql 的登录密码
mysqladmin -u root -p password "1999612"
10、授权远程登录
mysql -u root -p1999612
安装配置 PHP 解析环境
1.安装环境依赖包
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.解压配置及编译安装
cd /opt
tar jxvf php-7.1.10.tar.bz2
cd 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
make && make install
3.路径优化
ln -s /usr/local/php/bin/* /usr/local/bin/
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：
php.ini 主配置文件
php-fpm.conf 进程服务配置文件
www.conf 扩展配置文件
4.1调整主配置文件：
cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini
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
php -m #验证安装的模块
####
4.2调整进程服务配置文件：
cd /usr/local/php/etc/
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
--17行--去掉";"注释
pid = run/php-fpm.pid
4.3调整扩展配置文件：
cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf
5.启动php-fpm
/usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini
netstat -anpt | grep 9000
cd /opt/php-7.1.10/sapi/fpm
cp php-fpm.service /usr/lib/systemd/system/php-fpm.service
systemctl restart php-fpm.service
6.配置 Nginx 支持 PHP 解析
vim /usr/local/nginx/conf/nginx.conf
--65行--取消注释，修改
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; #将 /scripts 修改为nginx的工作目录
include fastcgi_params;
}
systemctl restart nginx.service
7.验证PHP 测试页
vim /usr/local/nginx/html/index.php
<?php
phpinfo();
?>
浏览器访问
http://192.168.239.10/index.php
8.验证数据库工作是否正常
mysql -u root -p
CREATE DATABASE bbs;
GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY '1999612';
GRANT all ON bbs.* TO 'bbsuser'@'localhost' IDENTIFIED BY '1999612';
flush privileges;
vim /usr/local/nginx/html/index.php #替换原来的测试页内容
<?php
$link=mysqli_connect('192.168.80.10','bbsuser','admin123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>
浏览器访问
http://192.168.239.10/index.php
部署论坛
部署
cd /opt
unzip Discuz_X3.4_SC_UTF8.zip -d /opt/dis
cd /opt/dis/dir_SC_UTF8/
cp -r upload/ /usr/local/nginx/html/bbs/
调整论坛目录的权限：
chmod -R 777 ./config/
chmod -R 777 ./data/
chmod -R 777 ./uc_client/
chmod -R 777 ./uc_server/
论坛页面访问
http://192.168.80.10/bbs/install/index.php
访问论坛页面：
http://192.168.80.10/bbs/index.php
http://192.168.80.10/bbs/admin.php 此为管理员登录
fpm参数优化
Nginx的PHP解析功能实现如果是交由FPM处理的，为了提高PHP的处理速度，可对FPM模块进行参数的调整
根据服务器的内存与服务负载，调整FPM模块参数
vim /usr/local/php/etc/php-fpm.conf
pid = run/php-fpm.pid
vim /usr/local/php/etc/php-fpm.d/www.conf
--96行--
pm = dynamic #fpm进程启动方式，动态的
--107行--
pm.max_children=20 #fpm进程启动的最大进程数
--112行--
pm.start_servers = 5 #动态方式下启动时默认开启的进程数，在最小和最大之间
--117行--
pm.min_spare_servers = 2 #动态方式下最小空闲进程数
--122行--
pm.max_spare_servers = 8 #动态方式下最大空闲进程数
kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid` #重启php-fpm
netstat -anpt | grep 9000
ps -elf | grep php-fpm
