centos中安装并配置nginx+MySQL+Php_linux centes 安装nginx php mysql-优快云博客

本文介绍如何在CentOS系统上配置LNMP环境，包括防火墙设置、安装Nginx、MySQL及PHP等关键步骤，并对配置文件进行了详细说明。

1.配置防火墙

打开80和3306端口

例子：[root@Centos66 ~]# cat /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 995 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 993 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 27017 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 9200 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 177 -j ACCEPT
COMMIT

2.启动防火墙

service iptables start

3.关闭SELINUX

例：[root@Centos66 ~]# cat /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
#SELINUX=enforcing
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
#SELINUXTYPE=targeted

并用init6命令重启系统

4.安装第三方yum源

4.1.先安装wget：yum install wget

4.2.下载atomic：wget http://www.atomicorp.com/installers/atomic

4.3.安装atomic：sh ./atomic

4.4.更新yum源：yum check-update

5.安装nginx：yum install nginx -y

5.1.设置nginx 开机启动:chkconfig nginx on

5.2.启动nginx:service nginx start

6.安装MySQL

6.1.yum install mysql mysql-server -y

6.2.service mysqld start

6.3.chkconfig mysqld on

6.4.cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

6.5.设置root密码：mysql_secure_installation

7.安装Php

7.1.yum install php php-fpm -y

7.2.安装php组件以支持mysql

yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt

7.3.chkconfig php-fpm on

7.4.service php-fpm start

7.5.配置nginx以支持php

7.5.1.备份原有配置文件：cp /etc/nginx/nginx.conf /etc/nginx/nginx.confbak

7.5.2.修改运行权限：user nginx nginx;

/etc/nginx/nginx.conf文件例子：

user nginx nginx;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 300;

gzip on;

client_max_body_size 300M;

upstream mytomcats{
server 192.168.1.197:8080;
server 192.168.1.26:8080;
# server 192.168.1.56:8080;
}

server {
listen 80;
server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root html;
index index.php index.html index.htm;
# proxy_pass http://www.baidu.com;
}

#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}

# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;

# location / {
# root html;
# index index.html index.htm;
# }
#}

# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;

# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;

# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;

# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;

# location / {
# root html;
# index index.html index.htm;
# }
#}

7.5.3.备份原有配置文件：cp /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.confbak

7.5.4.添加index.php到缺省首页：index index.php index.html index.htm;

并且放开如下部分

location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}

而且改为：

location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;
}

并重启nginx：service nginx restart

8.配置Php

8.1.修改/etc/php.ini：

date.timezone = PRC

expose_php = off

short_open_tag = ON

8.2.配置Php-fpm

备份：cp /etc/php-fpm.d/www.conf /etc/php-fpm.d/www.confbak
