nginx安装步骤

1、下载 Nginx，下载地址：https://nginx.org/en/download.html
[root@bogon src]# cd /usr/local/src/
[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz
2、解压安装包
[root@bogon src]# tar zxvf nginx-1.6.2.tar.gz
3、进入安装包目录
[root@bogon src]# cd nginx-1.6.2
4、编译安装
[root@bogon nginx-1.6.2]# ./configure —prefix=/usr/local/webserver/nginx —with-http_stub_status_module —with-http_ssl_module —with-pcre=/usr/local/src/pcre-8.35
[root@bogon nginx-1.6.2]# make
[root@bogon nginx-1.6.2]# make install
5、查看nginx版本
[root@bogon nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v

到此，nginx安装完成。

Nginx 配置

创建 Nginx 运行使用的用户 www：
[root@bogon conf]# /usr/sbin/groupadd www
[root@bogon conf]# /usr/sbin/useradd -g www www
配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
[root@bogon conf]# cat /usr/local/webserver/nginx/conf/nginx.conf

user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;

{
use epoll;
worker_connections 65535;
}

}
检查配置文件nginx.conf的正确性命令：
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t

启动 Nginx

Nginx 启动命令如下：
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx

访问站点

从浏览器访问我们配置的站点ip：

Nginx 其他命令

以下包含了 Nginx 常用的几个命令：
/usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen # 重启 Nginx
/usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx

启动MySQL服务器程序，确认状态

1）启动MySQL服务程序
启动服务并查看状态：
[root@dbsvr1 pub]# service mysql start
Starting MySQL… [确定]
[root@dbsvr1 pub]# service mysql status
MySQL running (31724) [确定]
服务器进程为mysqld，监听的默认端口为TCP 3306：
[root@dbsvr1 pub]# netstat -anpt | grep mysql
tcp 0 0 :::3306 :::* LISTEN 31724/mysqld
2）查看MySQL服务器进程、运行用户
提供连接服务的进程为mysqld，由其父进程mysqld_safe启动。
[root@dbsvr1 pub]# ps -elf | grep mysqld

4 S root 31619 1 0 80 0 - 2834 wait 15:14 pts/0 00:00:00 /bin/sh /usr/bin/mysqld_safe —datadir=/var/lib/mysql —pid file=/var/lib/mysql/dbsvr1.tarena.com.pid

4 S mysql 31724 31619 0 80 0 - 252496 poll_s 15:14 pts/0 00:00:01 /usr/sbin/mysqld —basedir=/usr —datadir=/var/lib/mysql —plugin-dir=/usr/lib64/mysql/plugin —user=mysql —log-error=/var/lib/mysql/dbsvr1.tarena.com.err —pid-file=/var/lib/mysql/dbsvr1.tarena.com.pid
数据库的默认存放位置为 /var/lib/mysql：
[root@dbsvr1 pub]# ls /var/lib/mysql/
auto.cnf ibdata1 mysql RPM_UPGRADE_HISTORY
dbsvr1.tarena.com.err ib_logfile0 mysql.sock RPM_UPGRADE_MARKER-LAST
dbsvr1.tarena.com.pid ib_logfile1 performance_schema test
