nginx安装笔记
双节点安装
1 节点一
1.1 目录
/usr/local
cd /usr/local
1.2 openssl
rpm -ql openssl
/usr/share/doc/openssl-1.0.0
# ./configure --prefix=/usr/local/nginx --with-pcre=/usr/share/doc/pcre-7.8/ --with-zlib=/usr/share/doc/zlib-1.2.3 --with-openssl=/usr/share/doc/openssl-1.0.0
1.3 pcre库
# rpm -qa | grep pcre
pcre-7.8-6.el6.x86_64
[root@r7 software]# rpm -qa | grep pcre
pcre-7.8-6.el6.x86_64
[root@r7 software]#
[root@r7 software]# rpm -e pcre-7.8-6.el6.x86_64
error: Failed dependencies:

[root@r7 software]#
[root@r7 software]#
[root@r7 software]# rpm -e --nodeps pcre-7.8-6.el6.x86_64
[root@r7 software]# mkdir /usr/local/pcre
[root@r7 software]# rpm -ivh --prefix=/usr/local/pcre/ pcre-7.8-6.el6.x86_64.rpm
无法安装，重新只用rpm –ivh安装后使用rpm –ql 查看安装路径
[root@r7 software]# rpm -ql pcre
/lib64/libpcre.so.0
/lib64/libpcre.so.0.0.1
/usr/bin/pcregrep
/usr/bin/pcretest
/usr/lib64/libpcrecpp.so.0
/usr/lib64/libpcrecpp.so.0.0.0
/usr/lib64/libpcreposix.so.0
/usr/lib64/libpcreposix.so.0.0.0
/usr/share/doc/pcre-7.8
pcre要使用源码包，不然在安装nginx时会编译pcre，这时会报错。
1.4 zlib库
rpm -qa | grep zlib
zlib-devel-1.2.3-29.el6.x86_64
zlib-1.2.3-29.el6.x86_64
zlib也要使用源码包
1.5 nginx安装
cd /usr/local/
tar -xzvf nginx-1.2.8.tar.gz
cd nginx-1.2.8
./configure --prefix=/usr/local/nginx
需要pcre包
./configure --prefix=/usr/local/nginx --with-pcre=/usr/share/doc/pcre-7.8/
需要zlib包
./configure --prefix=/usr/local/nginx --with-pcre=/usr/share/doc/pcre-7.8/ --with-zlib=/usr/share/doc/zlib-1.2.3
需要OpenSSL
# ./configure --prefix=/usr/local/nginx --with-pcre=/usr/share/doc/pcre-7.8/ --with-zlib=/usr/share/doc/zlib-1.2.3 --with-openssl=/usr/share/doc/openssl-1.0.0

make 时，在编译pcre时报错。换作pcre的源码包重新编译ngnix
cd /usr/local/nginx-1.2.8
# ./configure --prefix=/usr/local/nginx --with-pcre=/usr/local/pcre-8.02 --with-zlib=/usr/share/doc/zlib-1.2.3 --with-openssl=/usr/share/doc/openssl-1.0.0

2 节点二
nginx依赖openssl、pcre、zlib的源码包。
2.1 安装包
nginx-1.2.8.tar.gz
openssl-1.0.1c.tar.gz
pcre-8.02.tar.gz
zlib-1.2.8.tar.gz
解压安装包至 /usr/local 目录
openssl如果使用rpm安装的话，需要两个都安装
# rpm -qa | grep openssl
openssl-1.0.0-27.el6.x86_64
openssl-devel-1.0.0-27.el6.x86_64
openssl-devel 安装需要的依赖包比较多，配置 yum 可简化安装
本次安装使用
2.2 安装nginx
[root@r8 local]# ls
bin etc games include lib lib64 libexec nginx-1.2.8 openssl-1.0.1c pcre-8.02 sbin share src zlib-1.2.8
[root@r8 local]#
[root@r8 local]# cd nginx-1.2.8/
[root@r8 nginx-1.2.8]# pwd
/usr/local/nginx-1.2.8
[root@r8 local]#
[root@r8 local]# mkdir nginx
[root@r8 local]# cd nginx-1.2.8/
[root@r8 nginx-1.2.8]# ./configure --prefix=/usr/local/nginx --with-pcre=/usr/local/pcre-8.02 --with-zlib=/usr/local/zlib-1.2.8 --with-openssl=/usr/share/doc/openssl-1.0.0
有一些东西没有找到，比如下面的资源，但不影响安装
checking for sys/filio.h ... not found
make
make install
需要说明的是，pcre与zlib的安装，下载相关源码并解压到/usr/local，在configre时使用—with-pcre和—with-zlib指向其解压目录即可。而openssl服务器上已经有了openssl-1.0.0-27.el6.x86_64，我以yum方式安装了openssl-devel-1.0.0-27.el6.x86_64，也可以卸载openssl进行源码安装，然后使用—with-openssl指向其安装目录即可。
3 常用操作
3.1 启动
[root@r8 sbin]# netstat -ntpl | grep 80
tcp 0 0 0.0.0.0:31713 0.0.0.0:* LISTEN 2803/gpnpd.bin
[root@r8 sbin]# pwd
/usr/local/nginx/sbin
[root@r8 sbin]# ./nginx
[root@r8 sbin]# netstat -ntpl | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 27496/nginx
tcp 0 0 0.0.0.0:31713 0.0.0.0:* LISTEN 2803/gpnpd.bin
3.2 配置conf
[root@r8 nginx]# cd conf/
[root@r8 conf]# pwd
/usr/local/nginx/conf
[root@r8 conf]# ls
fastcgi.conf fastcgi_params.default mime.types nginx.conf.default uwsgi_params
fastcgi.conf.default koi-utf mime.types.default scgi_params uwsgi_params.default
fastcgi_params koi-win nginx.conf scgi_params.default win-utf
[root@r8 conf]# vi nginx.conf
#user nobody;
worker_processes 1;
3.3 重启
# 语法检查
[root@r8 sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
# 重启
[root@r8 sbin]# ./nginx -s reload
4 常用配置
5 遇到问题
5.1 PID错误
[root@r8 sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@r8 sbin]#
[root@r8 sbin]#
[root@r8 sbin]#
[root@r8 sbin]# ./nginx -s reload
nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"
查看nginx.conf配置文件
[root@r8 conf]# vi nginx.conf
#user nobody;
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;
}
解决方法：使用nginx –c重新配置nginx.conf文件
[root@r8 sbin]# ./nginx -c /usr/local/nginx/conf/nginx.conf
[root@r8 sbin]# ./nginx -s reload
[root@r8 sbin]#
