CentOS 安裝 nginx-1.19.4 與原版本共存

1、下載nginx

http://nginx.org/en/download.html

wget  http://nginx.org/download/nginx-1.19.4.tar.gz

2、解壓，進入目錄

tar -zxvf nginx-1.19.4.tar.gz

cd nginx-1.19.4

3、修改nginx http header server顯示

vim src/http/ngx_http_header_filter_module.c   

找到

static u_char ngx_http_server_string[] = "Server: nginx" CRLF;
static u_char ngx_http_server_full_string[] = "Server: " NGINX_VER CRLF;
static u_char ngx_http_server_build_string[] = "Server: " NGINX_VER_BUILD CRLF;

修改為

static u_char ngx_http_server_string[] = "Server: XXX" CRLF;
static u_char ngx_http_server_full_string[] = "Server: XXX" CRLF;
static u_char ngx_http_server_build_string[] = "Server: XXX" CRLF;

4、編譯安裝到/usr/local/nginx119

./configure --prefix=/usr/local/nginx119 --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-pcre --with-http_realip_module --with-stream --with-http_v2_module

報錯：./configure: error: the HTTP rewrite module requires the PCRE library.

解決：yum -y install pcre-devel openssl openssl-devel

再次 ./configure --prefix=/usr/local/nginx119  --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-pcre --with-http_realip_module --with-stream --with-http_v2_module

通過

make -j 

make install

5、查看安裝是否成功

cd /usr/local/nginx119/sbin

./nginx

6、舊版本配置文件遷移

7、配置新的nginx服務，以nginx119命名

nginx.conf 設置

pid        /var/run/nginx119.pid;

到nginx目錄下新生成nginx可執行程序軟連接nginx119

ln -s nginx nginx119

生成新的服務腳本

------------------------------------centos 6.x start ------------------------------------------------------------

cd /etc/init.d/

cp nginx nginx119

vim nginx119

修改路徑相關內容如下：

nginx="/usr/local/nginx119/sbin/nginx119"
prog="$(basename $nginx)"

sysconfig="/etc/sysconfig/${prog}"
lockfile="/var/lock/subsys/nginx119"
pidfile="/var/run/${prog}.pid"

NGINX_CONF_FILE="/usr/local/nginx119/conf/nginx.conf"

創建sysconfig文件

cd /etc/sysconfig/
cp nginx nginx119
vim nginx119
修改原有內容為：

NGINX_CONF_FILE="/usr/local/nginx119/conf/nginx.conf"

service nginx119 start 

service nginx119 status

service nginx119 stop

測試都沒問題

------------------------------------------------centos 6.x end --------------------------------------------

-----------------------------------------------centos 7.x start --------------------------------------------

cd /usr/lib/systemd/system

cp nginx.service nginx119.service

vim nginx119.service

[Unit]

# Nginx will fail to start if /run/nginx.pid already exists but has the wrong
# SELinux context. This might happen when running `nginx -t` from the cmdline.

systemctl start nginx119.service

systemctl status nginx119.service

systemctl stop nginx119.service

測試都沒問題

-----------------------------------------------centos 7.x end-----------------------------------------------

7、配置開機啟動

------------------------------------------------centos 6.x start --------------------------------------------

chkconfig nginx119 on

chkconfig nginx off　　# 關閉原來nginx自動啟

chkconfig                    # 查看是否開機啟動成功

-----------------------------------------------centos 6.x end --------------------------------------------

------------------------------------------------centos 7.x start --------------------------------------------

systemctl enable nginx119.service

systemctl disable nginx.service　　# 關閉原來nginx自動啟

systemctl status nginx119.service    # 查看是否開機啟動成功

 

-----------------------------------------------centos 7.x end --------------------------------------------
