CentOS安装Nginx

为了方便快捷的搭建linux环境，因而有了这几篇文字

1. CentOS使用yum安装jdk
2. CentOS安装tomcat
3. CentOS安装Nginx
4. CentOS安装MySql

1.安装Nginx前的准备
请确认gcc g++开发类库是否装好。

yum -y install gcc automake autoconf libtool make(安装make)

yum install gcc gcc-c++(安装g++)

2.下载Nginx和其组件

cd /usr/local/src

安装openssl

wget http://www.openssl.org/source/openssl-fips-2.0.16.tar.gz(下载openssl)
tar -zxvf openssl-fips-2.0.16.tar.gz
cd  openssl-fips-2.0.16
./configure && make && make install

安装pcre

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.42.tar.gz(下载pcre)
tar -zxvf pcre-8.42.tar.gz
cd pcre-8.42
./configure && make && make install

安装zlib

wget http://zlib.net/zlib-1.2.11.tar.gz(下载zlib)
tar -zxvf zlib-1.2.11.tar.gz
cd zlib-1.2.11
./configure && make && make install

或者用yum方式安装openssl、pcre、zlib

yum -y install openssl openssl-devel
yum -y install pcre pcre-devel
yum -y install zlib zlib-devel

安装nginx

wget http://nginx.org/download/nginx-1.15.0.tar.gz(下载nginx)
tar -zxvf nginx-1.15.0.tar.gz
cd nginx-1.15.0
./configure && make && make install

3.启动nginx

cd /usr/local/nginx/sbin/(进入nginx安装目录)

./nginx(启动命令)
报错信息：/usr/local/nginx/sbin/nginx: error while loading shared libraries: 
libpcre.so.1: cannot open shared object file: No such file or directory
whereis libpcre.so.1(查看libpcre.so.1安装位置)
位置信息：libpcre.so: /lib64/libpcre.so.0 /usr/local/lib/libpcre.so.1 /usr/local/lib/libpcre.so
ln -s /usr/local/lib/libpcre.so.1 /lib64（添加软连接再次启动就能够了）

4.修改nginx配置文件，配置域名添加反向代理指向tomcat

vi /usr/local/nginx/conf/nginx.conf

添加域名指向服务器，而且修改第一个server为如下配置：

server {
        listen       80;
        server_name  coder7911.club;
        location / {
            proxy_pass   http://127.0.0.1:8080;
        }
    }

5.nginx经常使用相关命令

./nginx
./nginx -t
./nginx -s relaod
ps -ef|grep nginx
kill -9 进程号
tail -f /usr/local/nginx/logs/access.log
