centos 安装 apache nginx php mariadb

rpm -Uvh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm[/code] 
2 安装 nginx

yum instal nginx


开启nginx服务

systemctl start nginx


查看nginx状态

systemctl status nginx


有如下信息表示服务正常开启

Active: active (running) since Wed 2017-01-18 05:37:48 UTC; 19h ago


设置开启启动

systemctl enable nginx


开启防火墙

firewall-cmd --add-service=http --permanent


查看下端口有没打开

iptables -n -L


如果看到如下信息, 表示服务开启正常

ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0            tcp dpt:80 ctstate NEW


3 安装apache

yum install httpd


因为nginx占用了80端口, 给apache换个88端口

vi /etc/httpd/conf/httpd.conf


将Listen 的端口改成 88

开启apache服务

systemctl start httpd


查看apache状态

systemctl status httpd


看到这个表明服务器开启正常

Active: active (running) since Tue 2017-01-17 02:48:38 UTC; 1 day 23h ago


然后你就可以看到apache的欢迎页面了.

设置开机启动

systemctl enable httpd


3 安装mariadb

mariadb是mysql的一个开源分支

yum install mariadb mariadb-server


开启mariadb服务

systemctl start mariadb


查看服务器状态

systemctl status mariadb


设置root密码

mysql_secure_installation


按照提示设置就可以了, 没什么特别

然后重启mariadb服务

systemctl restart mariadb


4  安装 php 及其扩展

yum install -y php php-fpm php-cli php-apc php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-magickwand php-mbstring php-mcrypt php-mssql php-soap libjpeg* php-bcmath php-mhash php-pecl-memcache


安装了一堆插件, 看自己想要增减

安装完之后, apache可以直接解析php了, 主要是在 /etc/httpd/conf.d 多了php.conf的配置文件, 然后照例写个测试

<?php
phpinfo();
?>


5 用php-fpm解析php

首先开启php-fpm服务

systemctl start php-fpm


配置nginx

{
listen 80;
server_name www.foo.com;
root /data/www/foo;
index index.html index.php;

location / {
if(!-e $request_filename) {
rewrite . /index.php last;
}
}

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

location ~/.ht {
deny all;
}
access_log /data/logs/foo.access.log;
}


使用 nginx -t, 发现出现如下错误

nginx: [emerg] unknown directive "if(!-e" in /etc/nginx/conf.d/foo.conf:9


度娘一下发现, if 和 ( 之间必须有个空格, oh, may god.

重新修改了一下

{
listen 80;
server_name www.foo.com;
root /data/www/foo;
index index.html index.php;

location / {
if (!-e $request_filename) {
rewrite . /index.php last;
}
}

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

location ~/.ht {
deny all;
}
access_log /data/logs/foo.access.log;
}


重启nginx, 没再发现错误了, 打开网站, 竟然出现502 502 502

502 Bad Gateway


再次度娘, 发现很多都说连接数不够的之类, 我网页都没打开过怎么可能出现连接数的问题~~

直到找到这位仁兄的文章, 才明了, 再次感谢这个困扰我那么旧的问题

竟然是yum安装时, 只允许127.0.0.1的地址接入, 而转发的是公网地址, 导致直接被deny, 可以通过日志查看

tail -f /var/log/php-fpm/*.log


如果看不到错误信息, 还要修改配置www.conf, 将

catch_workers_output = yes


再看看错误信息

WARNING: [pool www] child 22741 said into stderr: "ERROR: Connection disallowed: IP address '172.16.9.59' has been dropped."


只要将配置文件www.conf中的

listen.allowed_clients = 127.0.0.1


注销或者改成你的公网ip即可

其实还可以配置php-fprm使用unix套接字来处理php, 这样就可以避免了tcp的开销, 只需将

listen = 127.0.0.1:9000


改成

listen = /run/php-fpm/php5-fpm.sock


还要更改nginx的配置文件

{
listen 80;
server_name www.foo.com;
root /data/www/foo;
index index.html index.php;

location / {
if (!-e $request_filename) {
rewrite . /index.php last;
}
}

location ~\.php$ {
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass unix:/run/php-fpm/php5-fpm.sock;
fastcgi_index index.php;
}

location ~/.ht {
deny all;
}
access_log /data/logs/foo.access.log;
}


据说nginx配置文件还可以精简下, 尝试下改成这样

server
{
listen 80;
server_name www.foo.com;
index index.html index.php;
root /data/www/foo;

location / {
try_files $uri $uri/ /index.php$is_args$args;
}

location ~.php$ {
try_files $uri = 404;
include fastcgi.conf;
fastcgi_pass unix:/run/php-fpm/php5-fpm.sock;
}

location ~/.ht {
deny all;
}
access_log /data/logs/foo.access.log;
}


是因为fastcgi.conf已经包含了fastcgi_params里面的所有配置, 而且还包含了

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;


所以清爽了不少.
