CentOS搭建LNMP
CentOS搭建LNMP
前言：
我这里会讲解lamp架构的安装到配置，以及安装过程中的一些报错点
提示：这里的安装包括源码安装和yum安装
什么是lnmp？
nginx服务也通常和mysql、php一起使用，而这些通常都在linux系统下去运行，大家听说过lamp那lnmp概念也一样，就是把httpd服务替换成了nginx而已 lamp = linux + nginx + mysql + php文章目录
-
CentOS搭建LNMP - 一、源码编译安装部署lnmp
-
- ★安装之前的准备工作★
- 1.安装nginx
- 2.安装mysql
- 3.安装php
- 测试阶段
- 二、yum安装lnmp
一、源码编译安装部署lnmp
★安装之前的准备工作★
我这里使用的环境如下：
系统：CentOS7.9
ip地址：192.168.31.101
安装包：
nginx-1.21.6.tar.gz
mysql-boost-5.7.36.tar.gz
php-7.4.28.tar.gz
注意：需要多注意这些安装包的版本兼容性
安装包下载地址
nginx下载地址：http://nginx.org/download/
mysql下载地址：https://downloads.mysql.com/archives/community/
php下载地址：https://www.php.net/downloads.php
关闭防火墙和selinux
systemctl stop firewalld
setenforce 0
安装epel源，这样方便安装一些依赖包，要不然yum会没有一些包，再安装所需要的编译工具
yum install -y epel-release
yum clean all && yum makecache
yum -y install gcc gcc-g++ cmake make
现在就可以正式开始安装了。。。。。。
这里的安装顺序建议是php一般放到最后来，它是nginx和mysql的中间人，协调工作。
1.安装nginx
1.安装编译nginx时所需要的依赖包
yum -y install openssl openssl-devel pcre-devel curl-devel freetype-devel
2.创建nginx程序运行使用的用户
groupadd nginx && useradd -M -s /sbin/nologin nginx -g nginx
3.解压安装包编译安装nginx
tar zxf nginx-1.21.6.tar.gz && cd nginx-1.21.6
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module
make && make install
跟apache一样这里可以用./configure --help查询编译可以使用的一些参数
–prefix=/usr/local/nginx :指定安装路径
4.编辑nginx配置文件
vim /usr/local/nginx/conf/nginx.conf
-----------------------------------------
user nginx;
worker_processes 1;
error_log logs/nginx_error.log;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 300;
server {
listen 80;
server_name localhost;
access_log logs/nginx80.access.log;
location / {
root /var/www/html;
index index.html index.php;
}
location ~ \.php$ {
root /var/www/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
其中需要修改的就是
index index.php;
还有就是加入支持php转发到9000端口处理
location ~ .php$ {
root /var/www/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME d o c u m e n t r o o t document_root documentrootfastcgi_script_name;
include fastcgi_params;
}
查看nginx配置文件是否有问题
/usr/local/nginx/sbin/nginx -t
5.启动nginx服务
/usr/local/nginx/sbin/nginx
6.添加nginx服务到systemctl并优化服务命令路径（补充，也可以不要这一步骤，看个人）
nginx管理脚本：
vim /etc/init.d/nginx
-----------------------------------------
#!/bin/bash
# chkconfig: 2345 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start() {
echo -n $"Starting $prog: "
mkdir -p /dev/shm/nginx_temp
daemon $NGINX_SBIN -c $NGINX_CONF
RETVAL=$?
echo
return $RETVAL
}
stop() {
echo -n $"Stopping $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -TERM
rm -rf /dev/shm/nginx_temp
RETVAL=$?
echo
return $RETVAL
}
reload(){
echo -n $"Reloading $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -HUP
RETVAL=$?
echo
return $RETVAL
}
restart(){
stop
start
}
configtest(){
$NGINX_SBIN -c $NGINX_CONF -t
return 0
}
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo $"Usage: $0 {start|stop|reload|
restart|configtest}"
RETVAL=1
esac
exit $RETVAL
添加权限加入chkconfig
chmod +x /etc/init.d/nginx
chkconfig --add nginx
pkill nginx
systemctl restart nginx
2.安装mysql
1.yum安装mysql所需要的依赖包
yum -y install openssl openssl-devel prce pcre-devel bison bison-devel ncurses-devel
2.创建mysql用户给mysql程序使用
groupadd mysql && useradd -M -s /sbin/nologin mysql -g mysql
3.解压安装包，使用cmake工具编译安装mysql
#解压安装包
tar zxf mysql-boost-5.7.36.tar.gz && cd mysql-5.7.36
#cmake编译安装mysql
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_BOOST=boost -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci
make && make install
注意：在编译的时候注意一些参数跟下面第4点和第5点的参数和目录有联系，修改需谨慎，免得服务起不来找问题麻烦
编译的时间可能会等的有点久.。。。。。。就耐心等待吧！！！
4.使用mysql自带的mysqld命令初始化数据库,准备工作
/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/run/mysql.pid --initialize
这里初始化完成之后你会发现在你安装mysql的目录会自动生成data目录，这里还加载了mysql的pid文件的生成目录，记载mysql的pid进程号
5.创建准备mysql的一些工作目录
#创建日志目录并创建错误日志文件
mkdir -p /usr/local/mysql/run /usr/local/mysql/logs
touch /usr/local/mysql/logs/mysql_error.log
#把mysql的安装目录属主改为mysql，授权mysql程序pid运行目录755
chown -R mysql.mysql /usr/local/mysql
chmod 755 /usr/local/mysql/run
6.编辑mysql的配置文件
vim /etc/my.cnf
-----------------------------------------
[client]
socket = /usr/local/mysql/mysql.sock
[mysqld]
skip-grant-tables
port = 3306
user = mysql
character-set-server=utf8
socket = /usr/local/mysql/mysql.sock
pid-file = /usr/local/mysql/run/mysql.pid
log-error = /usr/local/mysql/logs/mysql_error.log
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
[mysqld_safe]
pid-file = /usr/local/mysql/run/mysql.pid
log-error = /usr/local/mysql/logs/mysql_error.log
7.启动服务并初始化服务密码
启动脚本在/usr/local/mysql/support-files这个目录下
/usr/local/mysql/support-files/mysql.server start
查看服务启动状态（mysql默认是3306端口）
netstat -anptu |grep 3306
登录数据库设置root密码
mysql -uroot -p
因为配置文件设置了skip-grant-tables参数，所以不需要密码直接进入，开始设置密码
flush privileges;
#进入mysql库下，修改root用户密码为123456
use mysql;
set password for root@localhost=password('123456');
#默认是只能本地登录，授权root用户所有地址都能登录
grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
flush privileges;
修改配置文件把skip-grant-tables这个参数注释掉（前面加上#号就行）或者删除，再重启服务
#skip-grant-tables
这里大家可以先去完成第8步直接使用systemctl命令重启
pkill mysqld
/usr/local/mysql/support-files/mysql.server start
mysql安装就完成了，可以使用了！！！
8.添加mysqld服务到systemctl并优化服务命令路径（补充，也可以不要这一步骤，看个人）
#mysqld服务加入systemctl方便管理,跟上面httpd服务原理一样
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
systemctl restart mysqld
systemctl status mysqld
#优化命令路径
ln -s /usr/local/mysql/bin/* /usr/bin
3.安装php
1.yum安装php所需要的依赖包
yum -y install php-bcmath php-mbstring sqlite-devel oniguruma-devel curl-devel freetype-devel libjpeg-devel libpng-devel libxslt-devel libxml2-devel zlib-devel
2.解压php安装包并编译
tar zxf php-7.4.28.tar.gz && cd php-7.4.28
./configure --prefix=/usr/local/php7.4 --enable-gd --with-jpeg --with-freetype --with-curl --with-zlib --with-zlib-dir --with-mysqli --with-config-file-path=/usr/local/php7.4 --enable-mysqlnd --enable-mbstring --enable-fpm --enable-bcmath --enable-sockets --enable-shared --with-gettext --with-openssl --with-pdo-mysql
make && make install
注意:--with-apxs2=/usr/local/httpd/bin/apxs这个选项不用加，是apache的模块
这里也同样可以使用./configure --help查询编译可以使用的一些参数
3.创建php用户和用户组
groupadd php && useradd -M -s /sbin/nologin php -g php
```powershell
4.编辑php配置文件
```bash
vim /usr/local/php7.4/php.ini

; FPM Configuration ;
;;;;;;;;;;;;;;;;;;;;;
[global]
pid = run/php-fpm.pid
error_log = log/php-fpm_error.log
include=/usr/local/php7.4/etc/php-fpm.d/*.conf
编辑www.conf子配置文件

pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
6.启动php-fpm
/usr/local/php7.4/sbin/php-fpm
7.编写php-fpm管理脚本，优化php命令路径
php-fpm管理脚本：
vim /etc/init.d/php-fpm
-----------------------------------------
#! /bin/sh
### BEGIN INIT INFO
# Provides: php-fpm
# Required-Start: $remote_fs $network
# Required-Stop: $remote_fs $network

exit 1
else
echo " done"
fi
;;

exit 1
fi
kill -USR2 `cat $php_fpm_PID`
echo " done"
;;
*)
echo "Usage: $0 {start|stop|force-quit|restart|reload|status}"
exit 1
;;
esac
添加权限加入chkconfig
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
pkill php-fpm
systemctl restart php-fpm
优化php命令路径
ln -s /usr/local/php7.4/bin/* /usr/bin
ln -s /usr/local/php7.4/sbin/* /usr/sbin
测试阶段
编辑php网页来测试lnmp架构环境的连通性和可行性
根据我上面的配置文件，我的网页目录是/var/www/html
创建nginx网页目录
mkdir -p /var/www/html
chown -R nginx.nginx /var/www/html
编写php网页
vim /var/www/html/index.php
-------------------------------------------
<?php
$servername = "localhost";
$username = "root";
$password = "123456";
try {
$conn = new PDO("mysql:host=$servername;port=3306", $username, $password);
echo "mysql数据库连接成功!!!
";
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
<?php
echo "mysqli方式连接mysql数据库:";
$a=mysqli_connect("localhost","root","123456");
if($a){echo "数据库连接成功!!!";}else{echo "数据库连接失败!!!";}
?>
<?php
phpinfo();
?>
注意：大家根据自己的配置文件配置的网页路径加入网页要不然会404！！！
浏览器访问192.168.31.101，出现页面如下图：
这样说明了lnmp架构搭建成功！！！
二、yum安装lnmp
#安装nginx,mariadb,php
yum -y install nginx php php-fpm php-mysql mariadb mariadb-server
#安装其他模块包
yum install -y php-devel php-common php-devel php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt libmcrypt-devel
systemctl start nginx php-fpm mariadb
#初始化数据库
mysql_secure_installation
记得在nginx.conf配置加入支持php配置项：
location / {
root /var/www/html;
index index.html index.php;
}
location ~ \.php$ {
root /var/www/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
注意：这里的网页目录根据自己的配置去设置
