CentOS6.7安装部署LNMP(nginx1.8.0+php5.6.10+mysql5.6.12)

IP-10.0.0.8

1.安装nginx

mkdir -p /server/tools
cd /server/tools
yum install -y pcre pcre-devel openssl openssl-devel gcc gcc+
wget http://nginx.org/download/nginx-1.8.0.tar.gz
useradd www -M -s /sbin/nologin
tar xf nginx-1.8.0.tar.gz
cd nginx-1.8.0/
sed -i "179s/#//" auto/cc/gcc
mkdir /application
./configure --prefix=/application/nginx-1.8.0 --user=www \
--group=www --with-http_stub_status_module --with-http_ssl_module
make && make install
ln -s /application/nginx-1.8.0/ /application/nginx
# Centos7采用yum方式安装nginx
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
yum -y install nginx
systemctl start nginx.service

2.安装php

yum -y install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel\
libpng-devel freetype-devel libcurl-devel gd-devel libxslt-devel \
mhash mcrypt libmcrypt libmcrypt-devel
# libiconv-devel没有这包
cd /server/tools/
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar xf libiconv-1.14.tar.gz
cd libiconv-1.14/
./configure --prefix=/usr/local/libiconv
make && make install
# PHP的编译参数
cd /server/tools/
wget http://cn2.php.net/distributions/php-5.6.10.tar.gz
tar -zxvf php-5.6.10.tar.gz
cd php-5.6.10
./configure --prefix=/opt/php --with-mysql \
--with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd \
--with-iconv-dir=/usr/local/libiconv  --with-zlib \
--with-libxml-dir --enable-xml --with-curl --enable-fpm \
--enable-mbstring --with-gd --with-openssl --with-mhash \
--enable-sockets --with-xmlrpc --enable-zip --enable-soap \
--with-libdir=/usr/lib64 --with-jpeg-dir=/usr/lib64 \
--with-freetype-dir=/usr/lib64 --with-png-dir=/usr/lib64 \
--with-xsl --with-fpm-user=www --with-fpm-group=www
make
make install clean

3.解决问题

# 安装MySQL参考上一篇博文
# 解决缺少共享库的问题,两种方法(先用find查到这个库的位置):
vi /etc/ld.so.conf
/opt/mysql-5.6.21/libmysql/
ldconfig  # 生效
ln -s /opt/mysql-5.6.21/libmysql/libmysqlclient.so.18 /usr/lib64/
# 如果make的时候报:ext/phar/phar.phar没有这个文件
cd php-5.6.10
touch ext/phar/phar.phar
# 本机没有安装mysql时,可以使用下面的参数
--enable-mysqlnd
--with-mysqli=mysqlnd
--with-pdo-mysql=mysqlnd
# 配置并启动php-fpm
cp php.ini-production /opt/php/lib/php.ini
cd /opt/php/etc/
cp php-fpm.conf.default php-fpm.conf
cd /server/tools/php-5.6.10/sapi/fpm/
cp init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
service php-fpm start # 或者/opt/php/sbin/php-fpm

cat blog.conf
server {
    listen       80;
    server_name  blog.etiantian.com;
    location / {
        root html/blog;
        index index.php index.html;
    }
    location ~.*\.(php|php5)?$ {
        root html/blog;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        include fastcgi.conf;
    }
}
/application/nginx/sbin/nginx -s reload
mkdir /application/nginx/html/blog/
echo "<?php phpinfo(); ?>" > /application/nginx/html/blog/test.php
# 连接数据库测试
cat /application/nginx/html/blog/conn_mysql.php
<?php
	$con = mysql_connect("localhost","root","root123") or mysql_error();
	if ($con){
		echo "connect mysql successfully";
	}
	else{
		echo mysql_error();
	}
?>

4.搭建WordPress博客

create database wordpress;
grant all on wordpress.* to wordpress@'localhost' identified by '123456';
show grants for wordpress@'localhost'\G;
# 如果授权授大了,在user表中删除用户是不行的,得drop然后重新授权
drop user wordpress@'localhost';
# revoke貌似不太好使
revoke all on *.* from wordpress@localhost;

wget https://cn.wordpress.org/wordpress-4.5.1-zh_CN.tar.gz
cp -a wordpress/* /application/nginx/html/blog/
# 这个权限是为了让先能用,以后还要改
chown -R www.www /application/nginx/html/blog/
# 现在blog目录下的文件有22个,安装后会多出一个配置文件
# 访问blog.etiantian.com,点击安装,会生成一个连接数据库的配置文件--wp-config.php
# 图片上传目录为:/application/nginx/html/blog/wp-content/uploads

5.分离数据库

# 导出wordpress数据并修改连接数据库的文件(web01上)
vi wp-config.php
define('DB_HOST', '172.16.1.51');
mysqldump -uroot -poldboy123456 wordpress -B | gzip > bak.sql.gz
# 导入数据(db01上)
mysql -uroot -poldboy123456 < /tmp/bak.sql
grant all on wordpress.* to wordpress@'172.16.1.%' identified by '123456';
# 在其他服务器上就能以这样的语句访问51的数据库了
mysql -u wordpress -h 172.16.1.51 -p

6.静态图片放在nfs上

# 10.0.0.31是之前的NFS服务器,在10.0.0.31上创建用户,与10.0.0.8上的www的id相同
useradd -u 891 www
vi /etc/exports
/data 172.16.1.0/24(rw,sync,all_squash,root_squash,anonuid=891,anongid=891)
mkdir /data/nfs-blog
chown -R www.www /data/
# 在web01上操作
rpm -qa rpcbind nfs-utils
/etc/init.d/rpcbind status
cd /application/nginx/html/blog/wp-content/uploads
mv 2018 /tmp/
mount -t nfs 172.16.1.31:/data/nfs-blog /application/nginx/html/blog/wp-content/uploads/
cp -a /tmp/2018/ .
排错:
touch: cannot touch `aaa': Permission denied
# 挂载完之后,无法创建文件,是因为在/etc/exports中将anonuid写成了893,
# 在改成891之后,还是无法写入,重启客户端rpcbind之后,可以正常写入.

7.wordpress实现伪静态

管理站点-设置-固定链接-自定义结构:
/archives/%post_id%.html
文章的url就会变成这样的形式:
http://blog.etiantian.com/archives/9.html

cat blog.conf
server {
    listen       80;
    server_name  blog.etiantian.com;
    location / {
        root html/blog;
        index index.php index.html;
        try_files $uri $uri/ /index.php?$args;
    }
    location ~ .*\.(php|php5)?$ {
        root html/blog;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        include fastcgi.conf;
    }

}
